Canada Blower forced draft fans fluidize and cool gravity conveying units. Dry material bulk density determines the amount and pressure of fluidizing air required. Canada Blower fans are supplied with inlet filters to avoid contamination of the product stream. Because the pressures required to fluidize the granular materials are usually more than one PSIG, the fans may require inlet silencers. The most common fan design is usually a direct drive arrangement with the motor being coupled directly to the fan wheel. Volume control can be affected by fan damper control. Some HVAC designers specify motor frequency control to create energy savings.

Canada Blower bearings and motors isolated from the process. Blower shaft seals with ceramic felt elements + housing clean out door + safety guards and electrical disconnect are standard; as well as ambient air fan inlet filter and blower silencers.
