Accessories Weatherhoods (for Arr. 10 only)* Drain Connection* Vented steel weatherhoods protect the motor and drive components from rain, moisture, dust, and dirt. Weatherhoods meet OSHA guidelines and are easily removed for service access. A one-inch (25 mm) threaded drain connection is located at the bottom of the fan housing to drain water that may accumulate. Belt Guard* The heat slinger is an aluminum cooling disc mounted on the fan shaft between the inboard bearing and the blower housing to dissipate heat conducted along the fan shaft. Heat slingers are not available for Arrangement...

Configurations Discharge Positions and Rotatable Housings All industrial process fans are available with clockwise (CW) or counterclockwise (CCW) rotation in all standard discharge positions. Fans sizes 5-19 feature rotatable housings as standard. Housings on IPO fan sizes 19 and less can be reversed in the eld to obtain either a clockwise or counterclockwise rotation. To change rotation on an IPA or IPW, a new wheel must be purchased. NOTE: Wheel must be turned around on shaft. Motor Positions — Arrangement 1 Fans Fan arrangement 1 requires a structural steel base or structural platform to...

Construction Options Alternative Materials Greenheck offers some industrial process fans in aluminum or stainless steel construction as an alternative to coated steel. Available constructions are shown in the table below. Aluminum construction provides advantages for applications with high moisture and various chemicals. Aluminum is suitable up to 250ºF (121ºC) and reduces the weight of the fan if there are building structural concerns. Stainless steel (316L) construction is used for environments subject to continuous high heat up to 1000ºF (538ºC) or severe corrosives. Both aluminum or...

Wheel Weight Heavy Duty Shaft Diameter Wheel Weight Shaft Diameter Weights, shown in pounds, are for steel fans and do not include motors, drives or accessories. Fan weights may vary up to 5% based on the discharge position.
