Fantech FR-140 6in Round Inline Centrifugal Duct Fan

Description

The Fantech FR-140 is a 6 inch round inline centrifugal exhaust fan approved for residential and commerical applications with airstream temperatures up to 140°F. The FR-140 comes with easy connections using external wiring box with waterproof gaskets.

A centrifugal type exhaust/supply fan specifically designed for moderate size ventilation applications. Fans are not designed for nor should be used in radon 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 accessory 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. All FR Series fans are backed by Fantech’s Five Year Warranty.
