Wheel Design 

BW – Back Plate Radial Wheel 

An open back plate radial blade wheel that is ideally suited 

for most air and material handling applications. This wheel is 

furnished with an inlet rim on heavy-duty units. Consult factory 

for special wheel construction on heavy-duty applications 

requiring a clog-free wheel. Available to size 63". 

OW – Open Wheel 

The open type wheel is recommended for applications handling 

heavy, granular, or abrasive materials. Air performance is less 

than that of the back plate design. Reinforcing rims are added 

to size 44" and larger in heavy-duty units. 

AW – Air Wheel 

The air wheel is designed for maximum efficiency when 

handling air, fumes, gases, or light concentrations of fine 

particulate matter. Eight slightly backwardly inclined blades 

allow for more efficient airflow into the fan.

Bearings and Drives 

Heavy-duty ball and spherical roller bearings are used on all 

arrangements, and are oversized to insure max-imum bearing 

life. The belts and sheaves on the belt-driven arrangements 

are manufactured by Browning, and are selected to provide 

additional allowances of 1.3 to 2 times the normal satisfactory 

capacity. 

Motors 

All motors are in NEMA type foot-mounted frames. Motor 

types available include totally-enclosed, cooled, totallyenclosed 

explosion-proof, or open-type drip-proof (with or 

without special insulations as required). 


Accessories 

Weather Cover 

Available on Arrangement 10 only, the weather cover is 

designed to enclose the motor, drive and bearing assembly, 

and is custom built to fit each unit. 

Flanged Inlet & Outlet 

For bolted connection, matching duct flanges are provided on 

both the inlet and outlet. Flanges are predrilled. Flanges are 

standard on heavy-duty fans. 

Belt and Shaft Guard 

Belt and shaft guards provide protection for personnel from 

moving parts. The belt guard includes a tachometer opening 

for checking the fan speed. 

Inlet Guard 

A spiral wire type safety guard is offered as an accessory for 

attachment to the fan inlet when no duct connection is used. 

Inlet Cone 

Available for sizes 16" through 79". Performances shown in 

this catalog are for MH fans with inlet cone and outlet ducts. 

Entrance loss must be added to static pressure calculated for 

the system when no inlet duct is used. For open inlets, that loss 

is equal to the fan velocity pressure. 

Example: 4,000 FPM velocity = 1" static pressure. Using 

the inlet orifice and guard such losses become 

minimal. 


Accessories 

Shaft Seal 

Four types of shaft seals are 

available: 

1. Elastomeric Rotary Seal 

— Rides against a heavy 

Teflon wear plate. Spare 

seal provided as standard. 

This seal is suitable for 

operation to 300°F. 

2. Ceramic Felt — Elements are encased between housing 

drive side and metal retaining plate. Ceramic felt inserts 

may be easily split for field installation and maintenance. 

This seal is best suited for 301°F to 600°F operation. These 

seals minimize leakage around shaft opening but are not 

gas-tight. 

3. Lubricated Seals — For longer seal life. Suitable to 300°F. 

4. Stuffing Boxes — Three rows of permanently lubricated 

padding material is encased between housing drive side and 

machined metal packing gland. The stuffing box shaft seal 

provides the best seal against gas leakage, but is not totally 

gas-tight. Specify temperature for proper packing material. 

Suitable to 500°F. 

Housing Drain 

A standard 1" FPT tank 

spud or half coupling is 

welded to the housing 

at the lowest point. Plug 

available on request. 

Housing Split 

Type A — Available with bottom 

horizontal, upblast, downblast, and 

top angular up discharge positions. 

Horizontal split allows removal of 

top section without disturbing inlet 

connection. Outlet connection must be 

broken on upblast and top angular up 

fans only. 

Type B — Available with top 

horizontal, top angular down, and 

bottom angular up discharge positions. 

Type B split allows removal of 

pie-shaped section without disturbing 

inlet or outlet connections. 

Unitary Base for Arrangement 1 Fans 

Structural steel channel bases which integrate the fan and 

motor together in one package are offered in all sizes. Each 

channel base is complete with a slide rail base. Base will be 

constructed in the following sizes: 

Size 12" through 22" ....................3" channel 


Size 35" and 39" .......................6" channel 



Bases are tailored to accommodate the specific motor and 

motor position selected for each fan. Consult with factory 

for dimensional information. Please specify AMCA motor 

position designation W, X, Y, or Z. Refer to page 8 for motor 

position diagram. 


Accessories 

Outlet Dampers 

Outlet dampers are available in two types: 

Parallel Blade — Has the lowest first cost and is best suited 

to applications re-quiring accurate air volume control from 

wide open to 75% of wide open. 

Vibration Isolators 

Rubber-in-shear or spring type vibration isolators are available 

for all sizes and arrangements. If rails or rail assemblies are 

required, consult factory for specifi-cations and pricing. 

Opposed Blade — Best suited for control over a broad 

range of air volume. Air reduction is in direct proportion to 

control arm movement. 

Standard Duty — Maximum operating temperature of 

300°F. Maximum S.P. is 15". 

Heavy Duty — Recommended for severe-duty appli-cations 

or where continual modulation is required. Maximum 

operating temperature is 500°F. Maximum S.P. is 22". 

Special construction required for applications over 22" S.P. 

and 500°F. 

Clean-out Doors 

Clean-out doors are available in two types: 

1. Quick opening, latch type and neoprene foam gasketed. 

2. Bolted type, gasketed. 

Doors are located at approximately 3 o’clock or 9 o’clock 

positions on housing scroll opposite fan discharge. If specific 

location is required, provide detailed information. 


Optional Construction 

Heat Fans 

MH fans can be used for operation at elevated temperatures 

provided certain modifications are made. 

The effect of various temperatures on material strength 

must also be considered. 

Maximum temperatures for each arrangement and fan 

modifications to meet these conditions are given in Table 2.

Corrosion Resistance 

Corrosion problems result when the air contains one or 

more chemicals which are corrosive in nature. The extent 

of the corrosion problem, however, varies with the specific 

properties of the chemical involved, the concentration, 

moisture, and temperature of the mixture. Protective coatings 

and special construction are available to combat corrosion 

problems. (See page 11 for further details.) 

Special Metal Construction — MH fans can be 

constructed of aluminum or various stainless steels. 

Thin Film Coatings (5 to 10 mils thickness) — Special 

paints and spray coatings are available under a variety of trade 

names. Aerovent works with coating applicators who can 

supply most brands or their equiv-alents. Standard MH fans 

with all-welded construction are especially suited to these 

coatings.

Performance Corrections For Temperature & Altitude 

Fan Calculations For Elevated 

Temperatures 

When a fan operates “cold,” it handles standard air at 70°F, 

29.92" barometric pressure weighing 0.075 pounds per cubic 

foot. When fans operate at temperatures other than 70°F or 

at altitudes other than sea level, corrections must be made for 

handling air at densities other than 0.075 pounds per cubic 

foot. Tables 5 and 6 give correction factors for operation at 

temperatures other than 70°F and altitudes above sea level. 

If speed, capacity, and barometric pressure are kept 

constant, static pressure and horsepower will vary inversely as 

the absolute temperature. 

Example: 

Specifications call for a size 20" fan, BW wheel, Arrangement 

1 heat fan to furnish 3,410 CFM at 5" SP at 600°F at sea 

level. 

1. Table 6 gives a 2.00 factor for 600°F. 

2. 5" SP x 2.00 = 10" SP at 70°F 

3. Performance tables show 2,511 RPM, 10.54 BHP, for 20" 

BW fan at 3,410 CFM at 10" SP at 70°F. 

4. Divide SP and BHP by the temperature factor. 

10 ÷ 2.00 = 5" SP 

10.54 ÷ 2.00 = 5.27 BHP 

5. Actual performance: 3,410 CFM at 5" SP at 2,511 RPM at 

5.27 BHP at 600°F. 

6. Check safe speed for standard size 20" BW at 70°F to 

400°F (Table 3 on page 7). RPM shown is 2,913. Correct 

for 600°F (Table 4 on page 7). Therefore, 2,913 x 0.94 = 

2,738 RPM. Fan is satisfactory for operation at 600°F. 

Fan Calculations For Altitude 

Other Than Sea Level (29.92") 

If speed, capacity and temperature are kept constant, static 

pressure and horsepower will vary directly as the density of 

the air. 

The method for correcting for altitude is the same as for 

temperature except using the factors in Table 5 instead of 

Table 6.

4000 1.16 9000 1.40 

4500 1.18 10000 1.45 

NOTE: If correction factor for both temperature and altitude is required, 

multiply factors from Tables 5 and 6 together: 3000 ft. and 600°F. 

Therefore, 1.12 x 2.00 = 2.24 (combined factor).

Dust Collecting & Pneumatic Conveying 

Pneumatic conveying embraces both dust collecting and 

conveying. In a typical system the amount of material 

transported is low compared to the amount of air used. 

Usually, a large quantity of fast-flowing air is needed to assure 

entrainment of material. Conse-quently, the materials moved 

have little effect on the performance of the fan. 

Where the sole purpose of the pneumatic system is to 

convey as much material as possible, different factors are 

involved. 

Dust Collecting & Fume Removal 

All airborne material, except fumes and the finest of dusts, 

will settle in ducts and fans if a minimum velocity is 

not maintained. Since in dust collecting the air quantity is 

determined by the hood size and velocity, it is usually most 

economical to maintain the lowest duct velocity that will keep 

the material in suspension. Raising the velocity raises the 

horsepower. For example, assume 1,000 CFM through a 12" 

pipe at 1,280 FPM with 0.2" resistance per 100 feet. Doubling 

the velocity while maintaining the same CFM would require an 

8 1 ∕2" pipe at 1.2" resistance per 100 feet. 

Some state codes give minimum velocities. Where no code 

applies, the figures shown in Table 9 may be used. 

When choosing the fan size for a dust collecting system, 

be certain that the velocity at the fan inlet and outlet is not 

lower than the minimum velocity required to keep the dust 

suspended. 

Material Conveying 

The problem of inducing the material into a conveying 

system is often a difficult one. The best overall method is 

one that feeds the material into the airstream evenly by either 

mechanical or gravity means. It is often required that the 

fan pick the material up as well as convey it. One misbelief 

frequently encountered is that the ability of a system to pick 

up material is due to the fan’s suction pressure. Suction in 

itself is useless. It is the velocity moving past the material that 

induces it to flow. For this reason, it is important not to plug 

up the entrance of the duct with material to be conveyed. 

It should be remembered, when figuring entrance loss to a 

conveying system, that where an appreciable amount of bulky 

material is to be moved, it may reduce the effective area of the 

inlet and thus increase the entrance velocity and loss. 

Since the purpose of a conveying system is to move a lot of 

material (as contrasted to dust collecting), the ratio of material 

to air volume is quite important. Experience has established 

good minimum velocities for common materials and these are 

given in Table 10. For those applications not listed, Chart B 

gives CFM/lb. of material and minimum velocities based on 

the weight of the material.

Dust Collecting & Pneumatic Conveying 

Wherever material is airborne, the fan must provide the energy 

to move the material. In small concentrations this is negligible, 

but in most conveying systems it is important. It is reflected 

as an increased resistance. Chart A gives the ratio of friction 

loss of the conveying system to the same system handling 

clean air 

The material conveying capacity of a system varies as the 

square of the velocity since it is a function of the velocity 

pressure. The economics of a given installation determine 

whether the minimum or a higher velocity shall be used. 

It is sometimes thought that a larger fan is naturally better 

than a smaller one. This is far from correct, since material 

is just as liable to settle in a fan as in a duct. If the inlet and 

outlet velocities of a fan are at least as high as the minimum 

conveying velocity, no settling should occur in the fan. 

Abrasion & Corrosion 

Certain materials can be highly abrasive by nature and, 

depending on the concentration and properties of the 

abrasive, can greatly affect the selection of the type of fan 

and wheel design. 

Proper fan and wheel selection alone may not satisfy 

the abrasive conditions. Special abrasive, impact, corrosion, 

and heat resistant materials or coatings may be required to 

further increase the life of the fan. Although Aerovent has 

the experience to recommend various materials or coatings to 

increase the life of the product, it must be recognized that to 

date no materials have been discovered that completely resist 

these conditions. Therefore, resistance to them is one of 

degree only.

Spark-Resistant Construction 

Described below are three classifications as defined by AMCA 

Standards for spark resistant construction. 

Type 

Construction Details 

“A” All parts of the fan in contact with the air or gas 

being handled shall be made of nonferrous material. 

Steps must also be taken to ensure that the impeller, 

bearings, and shaft are adequately attached and/or 

restrained to prevent a lateral or axial shift in these 

components. 

“B” The fan shall have a nonferrous impeller and 

nonferrous ring about the opening through which 

the shaft passes. Ferrous hubs, shafts, and hardware 

are allowed provided con-struction is such that a shift 

of impeller or shaft will not permit two ferrous parts 

of the fan to rub or strike. Steps must also be taken 

to ensure that the impeller, bearings, and shaft are 

adequately attached and/or restrained to prevent a 

lateral or axial shift in these components. 

“C” The fan shall be so constructed that a shift of the 

impeller or shaft will not permit two ferrous parts of 

the fan to rub or strike. 

NOTES: 

1. No bearings, drive components or electrical devices shall 

be placed in the gas stream unless they are constructed or 

enclosed in such a manner that failure of that component 

cannot ignite the surrounding gas stream. 

2. The user shall electrically ground all fan parts. 

3. For this standard, nonferrous material shall be any 

material with less than 5% iron or any other material with 

demonstrated ability to be spark resistant. 

4. The use of aluminum or aluminum alloys in the presence 

of steel that has been allowed to rust requires special 

consideration. Research, by the U.S. Bureau of Mines and 

others, has shown that aluminum impellers rubbing on rust 

steel may cause high intensity sparking. 

The use of the above standard in no way implies a guarantee 

of safety for any level of spark resistance. Spark resistant 

construction also does not protect against ignition of explosive 

gases caused by catastrophic failure or from any airstream 

material that may be present in a system. 


Narrow Width Construction 

Often it is desirable to have the performance characteristics of 

a narrow width wheel to satisfy certain design requirements; 

it becomes a necessity in broadening the performance range 

of direct connected fans. Reductions can be made up to 30% 

of a full width wheel. For a given RPM and SP, the CFM and 

BHP reduction is proportional to the percentage reduction in 

the wheel width. 

Example: 

1. Specifications call for an Arrangement 8 industrial exhaust 

fan to deliver 2500 CFM at 10" SP with a 1750 RPM 

motor. 

2. Several fans satisfy this requirement; however, from an 

efficiency standpoint, a model 25" BW would be the best 

selection. 

3. From the performance table on page 19 select a 25" BW 

fan operating at 1754 RPM. Under 10" SP note that the 

capacity is 3270 CFM. 

4. Wheel percentage is determined by dividing the required 

capacity by the catalogued capacity. Per-centage width = 

2500 ÷ 3270 = 76.5%. This should then be rounded off 

to the nearest higher per-centage, 77% wheel width. 

5. The BHP would then be 8.84 x 0.77 = 6.81 BHP. 

6. The fan then becomes a 77% width, heavy-duty, MH 

25" BW at 1750 RPM for 2500 CFM at 10" SP with 6.81 

BHP. 

This is all necessary to select the fan; however, if housing 

dimensions and outlet area are required, the following steps 

are necessary. 

7. From Table 11, complete the narrow width wheel: 

10 13 ∕32" x 0.77 = 8". 

8. Subtract narrow width from full width: 10 13 ∕32" – 8" = 

2 13 ∕32". 

9. Reduce housing width dimension (dimension “M”) by 

2 13 ∕32": 12 3 ∕16" – 2 13 ∕32" = 9 25 ∕32". 

10. The new outlet area can be approximated by multiplying 

the standard width area by the ratio of the narrow to 

standard housing width. 

Outlet Area = 1.09 ft 2 x 9 25 ∕32" ÷ 12 3 ∕16" = 0.875 ft.
