A radon fan is specialized piece of equipment that is used to exhaust radon gas. By creating a negative pressure beneath foundation of the home, radon no longer rises into the home and is harmlessly released in to the atmosphere.

There is many different models to choose from and it can be confusing to find the right fan for your situation. Let's see how we can make this process easier.

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.

Radon Mitigation Fan Selection

Choosing the right fan is very important for the success of your radon mitigation. 

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

  1. Your home's square footage
  2. The radon level
  3. What will the fan be pulling air through from under you house? Will you use a drain tile system? What are the soil conditions below the building?  Sand? Gravel? Clay?
  4. Will the fan be places 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.
