FW-Z Series Axial Flow Roof Fan

Description

FW-Z series axial flow roof fan consists of impeller, casing, mushroom hood, electric motor, loose-leaf damper and safety net. The casing is made of FRP material and has excellent corrosion resistance. The impeller adopts high-strength FRP wing-shaped blades with excellent aerodynamic and anti-corrosion properties. The fan casing and hood are detachable for easy installation and maintenance. The mushroom-type FRP hood is rain-proof and the loose-leaf damper is automatically opened. When the fan is stopped, the damper is closed to reduce the loss of heat in the winter room. The loose-leaf damper is a fan accessory, which is used by the user when ordering. The appearance of the motor is led to the safety switch outside the casing for easy wiring. The transmission mode is motor direct connection, belt drive or reducer drive.
