AIRFAN® SOFT BOX consists of a centrifugal fan and an MDF box. The enclosure is soundproofed with an internal coating of high-quality and durable insulating foam to minimize noise production. Since the fans are protected thanks to rubber rings, the fan has no direct contact with the frame, so it does not transmit any vibrations. These devices are designed to operate at high pressure, emitting as little noise as possible. Connections are designed for round pipes and pipelines.
