High suction fan

If you are concerned about radon levels in your home, you may want to learn how to quiet a radon fan. Radon fans need to suck air away from your house, but there is no specific rule on how loud they should be. Usually, they work best for homes with drain tile or gravel under the slab. These types of homes often have many cracks and are more prone to leaks than others.

Unlike standard ventilation fans, radon fans have a sealed motor casing to prevent radon gas from entering the fan. This keeps radon gas out of your home, while still preventing harmful levels. Most radon fans come with a 5yr warranty to ensure your safety. Remember that the warranty does not cover unlicensed installers. Some fans have bearings that may become noisy after about four to five months.


When choosing a radon mitigation system, a manometer is an important component. This device is a U-shaped tube that is filled with liquid (usually red, blue, or green) that measures static pressure, a key element in determining whether the radon fan is working properly. While passive radon mitigation systems don’t require a manometer, many do. The following are tips to help you choose a manometer that’s right for your home and your family.

Place the manometer beneath the radon fan in an accessible location. Be sure to level the tube to prevent it from slipping during installation. The reading should be close to the radon fan’s maximum pressure level, “WC.” If it’s lower, it’s time to find another fan. Below is a chart of common radon mitigation fan options. In general, however, a manometer is only one component of a radon mitigation system.

Size of radon fan

There is no universal rule for the size of a radon fan to quieten a house. Each manufacturer provides a sizing chart that relates CFM to static pressure inside the pipes. However, this chart is only helpful if you try several different fans to determine the appropriate size for your house. In some cases, you may need a fan that can extract more radon than the chart suggests.

The best way to determine the size of the radon fan to quieten your home is to check its manometer. If the fan draws less air than it is supposed to, it may gradually stop working and fail. It may also make noise in cold weather due to water or ice on the blades. Condensate from pipes above the fan can also trickle down and cause noise. However, this is not a sign of a major problem.

Ways to quiet radon fan

If you’re experiencing trouble with noise from your radon fan, you might want to consider purchasing a specialized radon mitigation fan. RadonAway’s RP Series Fan is designed for optimal performance and quiet operation, making it a popular choice for most sub-slab radon mitigation systems. If you’re not sure what to look for in a radon mitigation fan, read on for some tips to make your radon mitigation system as quiet as possible.

The motors of radon fans vary in terms of noise they produce. While installing a radon depressurization system, installers often use a higher-wattage fan for safety reasons. However, a 20-watt radon fan can save $500 over 10 years in electrical costs, and it’s considerably quieter. You can also ask the installer to install a lower-wattage fan to ensure you get a better night’s sleep.
