Model DPF offers belt-driven performance without the use of belts and pulleys. The key is an adjustable-pitch impeller that can be set to meet exact performance requirements. The direct-drive panel fan ships standard with a deep drawn venturi. Fan housings are available in several materials, including painted steel, aluminum and stainless steel. Impeller blade pitch adjustment can be carried out while still attached to the fan's drive shaft. Impeller blades are available in cast aluminum or nylon-glass fiber construction. Panels can be custom formed for non-standard applications. Performance ranges from 300 to 100,000 cfm.
