The BSI Square Inline Centrifugal Fan is specifically designed for duct applications handling relatively clean air, including supply, exhaust and return air systems. The BSI fan offers high efficiency and quiet operation in a compact design that can be mounted in any position (horizontal, vertical or angular). Duct collars are provided for easy mounting without the need for square to round duct transitions.
The BSI utilizes a non-overloading, backward inclined centrifugal wheel precisely matched to a spun venturi. All wheels are statically and dynamically balanced.
