Areas of application
HS-S041 duct filter housings have proven in numerous
applications. These housings fulfill maximum requirements
in regards of safety and efficiency in the field of particle and
gasfiltration. The HS-S041 series is especially designed for
safetyrelevant processes i.e.:
● Supply- & exhaustair with pharmaceutical or biotechnological
processes.
● Air treatment (supply / exhaust) with medical
facilities i.E. for safety environments at BSL 1 to 4
installations.
● Isolation wards and pandemic quarantine zones.
● Nuclear processes (fulfills KTA 3601).
● Exhaust air treatment for chemical processes.
● Isotope laboratories.
● other process air, requiring explosive protection
according to ATEX standards.
● Sterile air production.
● Deconamination / Warfare agent destruction
Filtration
The HS-S041 series can be equipped with pre-filtration for
coarse dust removal with classes EN779:G4 to M5.
The mainfilterstages might handle particle filters in classes
EN779:M6 to F9 for fine dust removal. But also HEPA filters
can be installed in classes EN1822:E11 to H14. Upon demand
even nominal ULPA classes are available.
Molecular filters can remove hazardous or radioactive gases
from the air flow.

Key features
HS-S041 duct filter housings can be adapted to any individual
need. The main features are:
● Filterhousing is made from stainless steel 1.4301,
on demand higher classifiactions.
● Gastight welded construction. The housing comes
fully welded and pressure tested if transport
limitations allow it. All connectors are then gastight
welded to the filterbanks.
● Standard pressure limit is up to +-100 mbar.
● Optional: pressure resistant up to +- 500 mBar.
● The selfregulating safety clamping frame ensures
all time for tightness between filters, gasket and
housing.
● All surfaces are glass blasted and passivated for
maximum corrosion resistance and easy decontamination.
● The filter housing is made from modular design to
be easily adapted to the requirements.
● Loads of innovative special options are availiable.
● Bypass test facilities according to DIN 1946-4 and
DIN 25414.
● Gastight DEHS-testports for particle
measurement / In-Situ testing.
● Mechanical installations ensure fail safe
operation and filter change.
● Temperature resistance is in accordance
with additional options up to >120°C.
● More safety by filter-chambers that can
be safe-locked to prevent unauthorized access.

Contruction, testing & documentation
HS-S041 duct filter housings consist by principle from welded
stainless steel (1.4301 or better). Any damages of a paint
coating that occures during transport or handling with usual
housings and the resulting risk of corrosion is avoided.
The sheet metal thichness is 2,5 mm by standard. It can be
up to 4mm in case higher pressure levels are demanded. Further
reinforcement such as splines and armoring is optionally
available. All surfaces are glass blasted and all welding seams
are carefully passivated. All HS-S041 duct filter housings
are intensively tested for pressure and tightness according to
the parameters of their application.

DIN 25 496; 6.2(4) is respected for all weldings, meaning
that stabilizing steels are used with austenitic materials.
All concerning parts and welding seams are free of cracks
and slits to ensure the ease of decontamination and to avoid
cranny corrosion. Upon the customers request all welding
seams can be tested such as for dye penetrant test or other
methods.
HS-S041 can be shipped as single module or as fully welded
ready to use housing. Single modules are supplied with hole
patterns on the conection flanges according to the customers
specification. Beside the usual documentations such as operational
manuals and declaration of conformity we also offer
added documents such as seismic stress simulations or approval
documents. Welding qualification certificates and raw
material certificates are part of our delivery and inspection
documentation in case full documentation is required.
Delivery & Installation
The filterhousings are supplied as complete unit along with
the connectors already welded if the transport and handling
situation allows this. Otherwise the housing is supplied in
easy to mount and install sections - typically for units consisting
of more than 4 - 5 units. The housings are fitted with
welded lifting eyes when needed.
By request we allso support you for installation, inspection or
final approval with our experienced staff on site.
Filter clamping / maintenance
The filter clamping construction is based on a uncomplicated
mechanical clamping to ensure maximum safeguarding
against failure. We therefore resign on pneumatic clamping
or electronic controls with this particular housing type.
The filter clamping construciton consists from stainless steel
clamping frame operated by excenters. Additional leafsprings
generate constant pressure to the filter to negate effects like
aging gaskets or production related tolerances of the filters.

change / issue Sept. 2011
Mounting Sys.
The clamping construction is designed to ensure tightness even with maxmum dust loading
of the filters and aging gaskets to always fulfills tightness requirements according to DIN
25496, Tab. 3 at the seat of each filter element. A filter can only be clamped when placed in
the correct position. The maintenance cover can only be fixed to the housing when a filter is
set in correctly and is properly clamped. This ensures failsafe operation.
Welded security barriers in the cover prevent a losening of the clamping in case of seismic
shocks.
The maintenance covers can be made lockable to prevent unauthorised access to the filterbanks.

DEHS-Testport for injection and measurement
of particles. The ports are gas tight sealed when
the filter is in operation. The constuction is either
made from tri-clamp-port or gas tight ball cocks.
The two-groove maintenance board (bag-in-bagout
filterchange) is made of a welded profile. The
profile is designed to firmly fix the O-Rings and
maintenance bags. The special profile prevents
that O-rings and bags accidentally flip away.
The optional maintenance table can be hooked
simply to the matching eyes to provide more comfort
during the Bag-In-Bag-Out filterchange.
On demand the housings can be fitted with gastight
dampers. These will shut off the housing during revision
and decontamination. All dampers come with a
leak-test groove to performin-situ tightness checks.
An optional pressure-discharge filter allows quick
pressure equalisation before a filterchange. Contaminated
air is lead over a gastight pressure valve to
a HEPA or ULPA safety filter.
Connectors for the injection or removal of
decontaminants (i.e. H 2 O 2 , formaldeyde) can be
defined and installed where needed.
