What's so special about a Radon Mitigation Fan?

Radon Fan
  • Designed to operate in wet conditions. Since the air pulled from the soil usually has a high moisture content these fans are built to handle excessive moisture.
  • The fan must run continuously to be effective. So energy efficiency is an important aspect of radon mitigation fan technology.
  • Quiet operation.
  • Durable fan housings. Radon pumps must be installed outside of the living space of the home. Which means often in the harsh conditions of attics, garages or even on the side of the building.
