Radon Mitigation Fans: Radon mitigation fans move less air than many bathroom fans (typically less than 60 CFM). Continuous operation is required yet inexpensive (similar to a 40-80 watt light bulb). Fans are designed to allow rain and all other water to pass through to the soil. Rain caps on pipe are not recommended.
Choices: It is a balance between vacuum pressure needed (based upon sub-slab conditions) and air volume needed (based upon cavity sizes and tightness. Experience in choosing the best radon mitigation fan is important. Bigger is not better yet too small will result in compromised effectiveness in cold weather. Oversized fans can cause noise, excess energy loss and problems with other building systems such as combustion appliances. Light duty fans may not be effective in reducing the levels of radon appropriately.
Noise: Most often noise problems are not from the radon mitigation fan itself. The problem is typically caused by the fan or piping touching. Piping must be installed to avoid vibration transfer to wood framing.
For homes built upon tight soil or sand (often older homes), high suction fans may be required and are capable of greater vibration. Choosing a smart fan location becomes important.
Open pipe – No caps
Radon Mitigation Fans and system piping must to be capable of letting water pass through and drop to the soil under the home. Each day about a 1/2 gallon of water builds up condensation within piping and drains to the soil. The air discharged is typically near 100% relative humidity. Ice and condensation will form on objects the air strikes. Ice can shut down systems with blockage and siding can rot with constant wetness, which makes it vital the open pipe is installed properly.
If installed properly: Systems should maintain effectiveness for as long as the radon mitigation fan is kept running.
