Industrial Exhausters

Internal fan measurement


Materials Handling

The Materials Handling Wheel is designed to handle and move air or gas containing granular materials, dust, buffing and grinding wheel exhaust, wood or metalworking machine exhaust. It is also used for dirty, tough or general industrial materials-handling applications. Wheels are heavy welded steel construction with six radial blades. Sizes from 12″- 84-¼” diameter, other sizes available. Available in standard and extra-heavy construction.

Paddle Wheel

The Paddle Wheel is a must for extremely dirty air streams or for material-conveying applications. These wheels are of heavy-duty welded construction, furnished with six radial blades, sizes 12″ through 85-¼”. Other sizes available.


All fans are furnished with fixed housings as standard, universal housings as optional, for sizes 12″ through 57-½”. Fan discharges are available to the locations indicated in the dimension sheets for either the standard fixed housing or the optional universal housing. Available fan arrangements are shown in the dimension section.

Split housing available as option. All-welded construction standard. Bolted construction can be furnished if requested. All standard discharges furnished. Other discharges available on request.

Special Features

The IE Exhauster is furnished with standard construction when operating with impeller tip speeds to 15,00 feet per minute. Extra-heavy construction is required, as indicated by the shaded areas on the multi-rating tables, when impeller tip speeds are in excess of 15,000 feet per minute. Extra-heavy construction will, in most cases, require an extra-heavy wheel, larger-than-standard shaft and bearings. A heavy-duty casing is furnished on standard and extra-heavy-duty units.

Special Materials of Construction IE Exhausters can be furnished fabricated from mild steel with the following protective coating: dipped or sprayed PVC, sprayed epoxy, aluminized, rubber linings or hot-dipped galvanizing. If required, equipment can be supplied with lead lining. Equipment also can be fabricated from 300 series alloy, monel, inconel, aluminum or other higher-grade alloy of various types. Abrasion-resistant materials also can be furnished.

Temperature Corrections

Where operation temperatures are other than 70° F, determine factor from the curve for the desired temperature. Divide pressure at operating condition by the factor taken from the curve. This provides the 70° F pressure condition. Select fan size from the capacity table, using the CFM desired and the corrected SP. Read the RPM and BHP from the table at this point. For horsepower at operating conditions, multiply the HP from the tables by the correction factor taken from the curve.
