DUCT PRE-FILTER UNITS 

Duct pre-filter units KPF are designed to clean the 

air in air-conditioning and ventilating systems. 

Built-in filters are of F5 to F7 class. Various types of 

duct housings enable the air filtration with air flow 

from 3.400 m 3 /h up to 20.400 m 3 /h. 

HOUSINGS WITH HEPA FILTERS 

Duct HEPA filter units AKF are constructed for 

installation in duct system. Built-in filters of H10 to 

H13 class remove up to 85 % particles of 0,3 μm 

(filters H10) or up to 99,95 % particles of 0,3 μm 

(filters H13). 

Wall HEPA filter units (AFH) and ceiling HEPA filter 

units (AFV-8) are used in both, supply and exhaust 

air ventilation and air-conditioning installations, 

which require maximal cleanness of the air. Built-in 

Hepa filters are of H10 to H14 class. They filter and 

remove particles with a diameter of 0,3 μm in 

different levels: from 85 % (filters H10) 

up to 99,995 % (filters H14). 

Ceiling HEPA filter units type AFV-8 G has a 

special washer frame for attachment the filter via gel 

gasket. AFV-8 G version guarantee absolute sit 

tightness for the filters up to class U16, which 

remove 99,99995 % of particles with diameter of 

0,12 μm. 

SUPPLY CEILINGS 

Supply ceilings with built-in HEPA filters of H10 to 

H14 class, are used for clean rooms where air 

cleanness as well as intensive air-exchange is 

required. They are constructed to be built in false 

ceilings of operation rooms, intensive care premises 

and other clean rooms.

Duct pre-filter units KPF 

Application: 

Duct pre-filter units KPF are built in supply air 

installations before rooms, which demand higher 

air cleanness. KPF units extend the service life of 

Hepa filters, because larger dirty particles are 

removed by pre-filters, which are built in the 

system before Hepa filters. 

Description: 

KPF unit comprises filter of B x H x L 

dimensions, filter frames and bag filters of F5 

to F7 class. Filter housing is made of sheet metal, 

air-tight welded according to DIN 1946 

and coloured in RAL 9010. Housing is fitted 

with connections for measuring of pressure drop. 

Galvanized steel sheet KPF possible (not airtight). 

Installation: 

Basic frames are being fitted into the KPF 

units via the side opening. The procedure requires 

1000 mm of free space (fig. 2). 

KPF housing is fitted into the duct network 

via the self-locking flange.

Duct Hepa filter units AKF 

Application: 

Duct Hepa filter unit AKF is being used in the 

network of inlet and outlet ducts used to supply or 

extract air from the rooms with highest demands 

regarding air cleanness. Hepa filters of H10 to H14 

class prevent the intake or exhaust of particles 

larger than 0,3 μm . They can be installed as 

follows: 

• air supply and extract in laboratories 

• air supply and extract in operation rooms, 

infection- and sterile departments 

• air supply in electronics, precision mechanics, 

chemistry, pharmaceutics and food industry 

• air supply in film and audio tape industry 

• air supply and extract in nuclear technology etc. 

Description: 

AKF unit is made of filter housing, connection 

flanges (fig. 3) and Hepa filter. Filter is fitted with 

washer of a rectangular cross-section. Filter 

housing is made oh sheet metal air-tight welded 

according to DIN 1946 and coloured in RAL 9010. 

Two pressure gauge attachments for measuring of 

a pressure drop are incorporated into the housing. 

Bag-in, bag-out design 

(Safe filter replacement with the use of bags): 

“Bag-in, bag-out“ design is intended for filtration 

of air from the processes during which hazardous 

or toxic substances are produced. The bag-in-out 

system prevents any contact with the contents of a 

waste filter when replacing it. The installation of a 

pre-filter prolongs the life of a Hepa filter. The 

system of pre-filter replacement is the same as 

Hepa filter replacement. 

Installation and design variations: 

AKF housing are designed for installation of single 

AKF-I filter units. (fig. 1) as well as installation of 

several AKF-II units (fig. 2) into the duct system. 

To replace the filter, 700 mm of free space is 

required on the front side of the unit. AKF-II unit is 

made in several design variations, determined by 

the position of connection flanges A1, A2, B1, B2 

(fig. 4).

Expected service life of Hepa filter 

and replacement 

Hepa filter are constructed for single use only. 

Expected service life of filter depends on air flow 

volume, pressure drop and amount of dust 

particles. When air flow volume is reduced 

for 25%, expected service life of Hepa filter 

doubles. Service life can be considerably 

increased with installation of pre-filter. 

Hepa filter pollution is controlled by means of a 

differential manometer (Picture 4) which is fitted 

on the housing. 

Connections for plastic tubes are fitted 

on AKF housing. 

The initial pressure drop is specified in table 2. 

When the pressure drop has reached double its 

initial value, it is recommended to replace the 

Hepa filter. When replacing the AKF filter, remove 

cover, release the lever and finally remove the 

frame with used Hepa filter. When installing the 

new filter, use the above instructions in opposite 

order. 

In case of replacement of filters using bags (bagin, 

bag-out system), the procedure is the same 

with the exception of a bag attached to the 

extension. The waste filter is removed into a bag, 

which has been attached to the extension since the 

last replacement. The bag is then hermetically 

closed so that after the separation of the part of the 

bag with the filter, a part of the bag remains on the 

extension, hermetically closed as well. A new filter 

is put in a bag and then placed over the remaining 

part closing the duct. Upon the placement of the 

new bag, the remaining part of the old bag is first 

removed into the new bag. A new filter is installed 

from the new bag. The bags are attached to the 

extension by means of a rubber collar.

KD-1, AKD-1, KD-6, OD-8 or OD-9 and Hepa filter. Filter is fitted with 

washer of a rectangular cross-section. Housing of sheet steel is air tight 

welded according to DIN 1946 and coloured in RAL 7001. Two pressure 

gauge attachments for measuring of a pressure drop are incorporated into the 

housing. Diffusers made of sheet steel are coloured in white (RAL 9010). 

AFV-8 housing has a special sealing frame designed to perform sit tightness 

test. 


1. Housing 

2. Hepa filter (with flat gasket) 

3. Diffuser 

Installation: 

AFV-8 unit is constructed to fit into suspended ceilings. 

Types: 

The following Hepa filter units AFV-8 are possible: 

• with circular side entry spigot (AFV-8 RS) (fig. 1, table 1) 

• with circular top entry spigot (AFV-8 RV) (fig. 2, table 1) 

• with rectangular side entry spigot (AFV-8 KS) (fig. 3, table 3). 

AFV-8 with shut-off damper ZL-2 

Application: 

On the ceiling Hepa filter unit AFV-8 a shut-off damper ZL-2 is installed in the 

housing connection. The shut-off damper ZL-2 conforms to the DIN 1946/4 

standard requirements. 

The advantage of such a combination of an Hepa filter housing and a shut-off 

damper is the ability to close the shut-off damper during the filter exchange and 

thereby to prevent room air pollution. Upon the completion of the filter 

exchange, the shut-off damper is reopened. Such a filter exchange procedure 

eliminates the need to disinfect the room, which is mandatory in the case of 

exchanging the filter without shutting-off the inlet of non-filtered air. 

Description: 

On the connection of the standard ceiling Hepa filter unit AFV-8, a galvanised 

sheet steel shut-off damper is mounted by means of four screws. The damper 

may be controlled either manually or by means of an electric motor.

Application: 

Ceiling Hepa filter units AFV-8U are used in air supply or extraction applications 

in air conditioning and ventilation installations in rooms requiring the 

highest standards of air purity. Hepa filters of H10 to H14 class prevent the 

intake of particles larger than 0.3 μm. 

They can be installed as follows: 


• air supply and extract in infection- and sterile departments 

• air supply in electronics, precision mechanics, chemistry, pharmaceutics and 

food industry 


Description: 

Ceiling Hepa filter units AFV-8U consists of the filter housing, standard diffuser 

and Hepa filter. The filter is fitted with a U-shaped washer, which enables 

testing of the sit tightness between filter and housing through the duct. Another 

solution is the semicircular gasket, which does not allow for airtighness testing 

between the filter and the housing. The lower part of the housing is made of 

sheet steel and is hermetically welded according to DIN 1946. The upper part is 

spot welded and attached to the lower part with the rivets. The housing is painted 

with RAL 9010. The diffuser (OD-9, KD-1, KD-6) is made of sheet steel and 

painted with RAL 9010 or is made of stainless steel. A perforated control 

damper can be built into the junction, and can be controlled easily from the 

clean side of the diffuser.

Ceiling Hepa filter units with gel gasket AFV-8G 

Application : 

Ceiling Hepa filter unit with gel gasket AFV-8G are installed in ventilating and 

air conditioning systems in rooms which require absolutely clean air. They can 

be used for both, air supply and extract applications. Hepa filters stop the 

particles as larger as 0,3 μm if they conform H14 class or even 0,12 μm if 

they conform U15 and U16 classes. 

Applications: 


• air supply and extract in operating theatres, infection- and sterile departments 





Description: 

Ceiling Hepa filter unit with gel gasket AFV-8G is made filter housing, standard 

diffusers KD-1, AKD-1, KD-6, OD-8 or OD-9 and Hepa filter. Housing of 

sheet steel is air tight welded according to DIN 1946 and coloured in RAL 

7001. Diffusers are made of sheet steel and coloured in white (RAL 9010). 

AFV-8G housing has a special sealing frame designed to fit “gasket” filters. 


1. Housing 

2. Hepa filter (with gel gasket) 

3. Diffuser 

Advantage of gel gasket: 

With liquid sealant force, necessary to hold the filter is smaller, compared with 

neoprene washers, permitting lighter and cheaper housing and faster filter 

replacement. 

Installation: 

AFV-8G unit is constructed to fit into suspended ceilings. 

Types: 

The following ceiling Hepa filter units with gel gasket are possible: 

• with circular side entry spigot (AFV-8G RS) (fig. 1, table 1) 

• with circular top entry spigot (AFV-8G RV) (fig. 2, table 1) 

• with rectangular side entry spigot (AFV-8G KS) (fig. 3, table 3). 

AFV-8G with shut-off damper ZL-2 

Application: 

On the Ceiling Hepa filter units with gel gasket AFV-8G a shut-off damper ZL-2 

is installed in the housing connection. The shut-off damper ZL-2 conforms to 

the DIN 1946/4 standard requirements. 

The advantage of such a combination of an Hepa filter housing and a shut-off 

damper is the ability to close the shut-off damper during the filter exchange and 

thereby to prevent room air pollution. Upon the completion of the filter 

exchange, the shut-off damper is reopened. Such a filter exchange procedure 

eliminates the need to disinfect the room, which is mandatory in the case of 

exchanging the filter without shutting-off the inlet of non-filtered air. 

Description: 

On the connection of the standard AFV-8G unit, a galvanised sheet steel shutoff 

damper is mounted by means of four screws. The damper may be controlled 

either manually or by means of an electric motor.

PERFORATED SUPPLY CEILING DPS 

Perforated supply ceiling DPS with Hepa filter 

Application: 

DPS with absolute filter is being used in clean rooms which require clean 

air but also frequent air-exchange within the working area. They are designed 

to be built-into the false ceilings of OP rooms and intensive care premises and 

to ensure the laminar flow of the absolute clean air into the target zone. 

The aim of the above device is to reduce the possibility of infection in OP 

rooms being caused by germs which are due to different causes constantly 

present in the premises and surroundings. 

Description: 

The preparation of air for the OP theatre is accomplished with separate air 

conditioning system, capable of rough and fine air-filtering according to DIN 24185. 

The filtered supply air is distributed to the absolute filter on the DPS plenum box. 

The air is discharged from the pressure chamber into the OP theatre via the 

perforated ceiling plates. The temperature of the discharged air is to be 1° to 3° C 

lower then the average room temperature. Two thirds of the air current should be led 

out of the room via the floor and one third via the ceiling. The air current which is 

being discharged from the DPS flows over the entire area under the ceiling thus 

preventing the surrounding air from penetrating within the operation area (fig. 1). 

Base material of pressure chambers and perforated plates: 

steel sheet painted with epoxy dusty paint RAL 9010, resistant to disinfectants 

Ceilings (except the size of 2000x1000) are composed of two parts, which are 

bolt together at the assembly point. In the assembly operations the connections 

are additionally packed with the acrylic putty, which is attached to the ceiling. 

At the consumer's request the ceiling contains a transition for the operating 

light of the dimensions 300 x 300 mm. In that case a blind plate and a plate 

with a round opening of φ150 mm. 

Perforated plates (from inside the ceiling) are covered with a PPI-20 black 

foam for a more uniform distribution of air. The delivered foam is packed in a 

foil in order to protect it from dirt and damage. 

Fixation of the perforated plates is on the one hand carried out with the help of 

hinges and on the other hand with the help of locks. 

The ceiling is fitted with the hepa filters 610x305x292, which belong to the class 

H13 or H14 and have been tested according to the DIN 24 185, which means that 

parts in diameter of 0.3μm are removed 99,95% and 99,995% respectively. They 

are fitted into the side connection on the longer side of the ceiling. The dimensions 

of the connection duct and the number of filters are given in the table. The inside 

of the ceiling is fitted with the filter pressure drop measurement connections (the 

difference between the pressure in front of and behind the filter, which serves to 

control the dirtiness of the filter) and with the DOP or PAO test connection. 

With the nominal flow rate of air, given in the table, the initial pressure drop 

is 250 Pa. At a filter load with larger or smaller flow rates than the nominal 

the pressure drop increases and decreases respectively, which is shown 

in the diagram. Leak-tightness of hepa filter at the sealing frame is 

in accordance with the DIN 1946 standard, Chapter 4. When changing filters 

one has to check the leak-tightness of the hinges. 

The ceiling, filter body, filters, PPI-20 foam and the assembly material are 

delivered separately. 

The assembly of ceilings to the concrete ceiling is carried out with the 

threaded bars and inners for the concrete. 

Hepa filter replacement: 

During the operation the permeability of the Hepa filter is decreased and the 

differential pressure increases. The permeability-loss rate is measured with 

differential manometer via the tubes fitted in front and after the filter. When the 

pressure drop has reached double its initial value, it is recommended to 

replace the Hepa filter. When replacing absolute filters, the first row of face 

plates has to be removed.

SUPPLY AIR CEILING - TEXTILE VERSION DSS 

Supply air ceiling- textile version DSS 

Application: 

DSS ventilation ceiling with polyester textile is used to air condition hospitals 

where intensive air exchange is required, in cleanrooms classified under US 

Fed Std 209 E and DIN 1946/4 standards. It is intended to be built into a suspended 

ceiling in operating rooms and intensive care facilities. 

Description: 

The basis of the ceiling is a standard DPS perforated ventilation ceiling whose 

panels are replaced with synthetic textile affixed to aluminum or stainless steel 

frames. The ceiling and filter housing may be either stainless steel or painted 

zinc-plated panels. 

The synthetic textile allows laminar flow, because the tight weave of the fibers 

prevents turbulent flow from forming on the surface. The polyester textile 

adheres to DIN 4799 standards for the hygienic minimum for operating rooms. 

It has also all the necessary certificates for use in operating rooms, and it has 

high resistance to aggressive disinfectants. The synthetic textile may be singlelayer 

or double-layer. The second layer allows the air to be evenly distributed 

across the entire surface before it enters the room. 

Ceilings are made of one, two or four parts, depending on size. All elements 

are screwed together at the installation site. Joints are additionally sealed with 

acrylic lute. 

At the customer’s request, the ceiling might be worked out with a transition for 

an operation lamp with dimensions of 300 x 300 mm. In this case a plate with 

a round opening for the lamp is attached. 

Fastening of the synthetic mask is done by special screws that are fixed 

manually, without special tools. 

Class H13 and H14 Hepa filters, sized 610x305x292, belonging to and tested 

according to DIN 24-185 (meaning that particles with a diameter of 0.3μm are 

removed at 99.95% and 99.995% rates respectively) are built into the ceiling. 

They are built in the connections from the side or from the top. Dimensions of 

the connecting channels and the number of filters are given in the table. 

Connection is possible from the side or from the top, depending on the 

customer’s requirements. Inside the ceiling, connectors are built for measuring 

the pressure drop on filters (the difference between the pressure before and 

after the filter, indicating how dirty the filter is), as well as a connection for 

DOP (PAO) test. 

When filters are loaded with flow volumes greater or lower than nominal, the 

pressure drop increases or decreases as shown on the diagram. 

After each filter change, a DOP test must be performed in accordance with 

standards.

Under the recommended flow rate, the effective air 

velocity is 2.5 m/s, and the pressure drop, Δp, 15 Pa. 

To determine the pressure drop, apply the 

equation and diagrams on page 441. 

Installation: 

The grille may be mounted flush with the wall face 

(Figure 1). 

Filter Insert Cleaning and Replacement: 

Due to dirt, which collects on the grille, it needs to 

be removed and cleaned from time to time. Due to 

the build-up of impurities, the grille must be 

removed and cleaned. Loosen the grille face screw 

and simply withdraw the grille face from the 

installation frame. With the LN-1/Filter variant, 

withdraw the filter insert from the frame and 

replace it by a new insert.

Filter grille 

Application: 

Grilles with a filter are intended to be built in the 

walls of rooms which require cleaner air (computer 

centres, libraries, clean rooms, etc,). Primarily used 

for exhaust air from the room. 

Description: 

Grilles are made of stainless (polish) sheet metal. 

The installed filter is of G2, G3, G4 or of F5 

quality. 

Dimensions: 

Standard dimensions of louvres are 225 x 75 mm 

to 1125 x 525. The depth of the grilles is 35 mm. 

Installation: 

Grilles may be fixed with visible screws (V 

marking, screws on the grille frame) or hidden 

into the installation frame (marking 2, grille is 

fastened on the installation frame with the lock on 

the internal side of the grille. Installation frame 

shall be fixed on the wall before the installation of 

the grille.) 

Filter replacement: 

Due to the dirtiness of a filter, the pressure drop on 

a louvre gradually increases, therefore it is 

necessary to replace the filter. The replacement of a 

filter is quick and simple. Lock may be used to 

open the grille and replace dirty filter with the new 

one. The mask is then closed by means of a lock.
