The Design 64 packaged backward inclined (PBI) fan can be used for dust collection, air filtration, and pneumatic conveying applications up to 150 °F. The PBI is a direct drive fan, so initial cost is less and belt drive maintenance is eliminated. Since some dust collector fans are installed outside the facility and are subject to year round environments, the C-face motor is bolted directly to the housing and caulked with adhesive sealant to provide weather-proofing and keep water out.
