Radon Fan Information Guide

What's so special about a Radon Mitigation 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 harsh conditions like attics, garages or even on the side of the building.

Radon Mitigation Fan Selection

A mitigation fan must be sized according to the a number a factors.

  1. Your homes square footage
  2. The radon level
  3. What will the fan be pulling air through from under your house? Will you use a drain tile system? What are the soil conditions below the building? Sand or gravel? Or clay?
  4. Will the fan be placed outdoors?

By considering these factors the fan can be sized accordingly, to take into account the suction needed versus air flow available. A proper sized fan will also keep your electric bill to a minimum.
