Centrifugal Fans and Blowers

Centrifugal fans and blowers are designed for the high efficiency exhausting of air with high pressure. They are commonly applied for ventilation and smoke exhaust in environments with particularly unclean air, like factories, mines, tunnels, ships, etc. The centrifugal fans and blowers are made up of a cabinet, frame, and plate. The plate is multiple layers with an interlayer of superfine glass fiber to prevent condensation buildup in humid environments. This also minimizes vibration and noise.
