Airmec Cutter / Conveyor Fans are equipped with high tensile steel impellers specifically designed for handling large volumes of waste materials and are built for heavy industrial use. They should not be confused with lightweight fans or those made from mild steel.

​

The fan impeller runs on a heavy-duty bearing block and is equipped with replaceable hardened steel cutting blades, which are of particular benefit when handling large volumes of waste materials.

​

Drive motors are typically up rated by an minimum of 50% above the fan absorbed power requirements to meet the heavy demands associated with waste conveying, and to ensure long motor life, providing flexibility for possible future changes to the system.
