Model BSQ centrifugal inline fan features a unique combination of installation flexibility, rugged construction, ease of service, high efficiency and low sound levels. These compact fans are the ideal selection for indoor clean air applications including intake, exhaust, return or make-up air systems where space is a prime consideration. The square housing design eliminates the need for square-to-round transitions, reducing installation costs. With straight-thru airflow, system designers also have flexibility to mount the BSQ in any configuration - horizontal, vertical or at any angle.

Removable access panels allow easy access to all interior components
Aluminum, centrifugal wheel delivers maximum efficiency
Inlet and discharge duct collars allow for easy duct connection
Rigid, galvanized steel housing construction
Factory tested bearings designed specifically for air handling applications with a minimum L₁₀ life in excess of 100,000 hours
Permanent embossed aluminum nameplate for exact model and serial number identification
