Attachment 2 Fans- Qty Required 4
Description A centrifugal type exhaust/supply fan specifically designed for moderate size ventilation applications. The fan can be mounted in any angle at any point along the duct work and straight-through air flow design allows easy installation. By using FC type mounting clamps fan can easily be removed from duct work for service. Fans are constructed in accordance with standard dimensions for spiral duct eliminating the need for transition pieces. Fan motors are capable of operating in air stream temperatures up to 140 oF. Motor bearings are permanently sealed, self lubricating ball type. All fans are 100% speed controllable through a decrease in the voltage by using a solid state or transformer type control.
