Product Overview

The RadonAway RP145 is the most popular radon mitigation fan in the industry, is intended for use as a component of an active soil depressurization (ASD) system for reducing radon. The RP145 offer higher air flow, energy efficiency and quiet operation. It is ideal for both new construction and retrofit radon systems with a slab or membrane size of up to 2500 sq. ft. This fan is designed for moderate to good air flow, working most effectively with sub slab or sub-material conditions ranging from about 4 in. of clean, size 4-6 gravel to very loose soil. The RP145 is built to resist moisture and can be mounted inside or outside on a 3 in. or 4 in. schedule 40 PVC vent pipe using 3 in. x 4 in. or 4 in. x 4 in. flexible couplings. NOTE: When installing an ASD system for radon reduction, any openings, major cracks and penetrations in the building slab or membrane must be sealed. Fan sizing for retrofit may require professional diagnostics and design.

Customer Questions & Answers

How long does this pump ladt

Asked by: Jody
I just purchased and installed my second Radon-away RP 145 Radon Mitigation Fan. The first one (same fan) lasted 4 years and 11 months of constant running. It actually never stopped working, but it gradually started to get a little bit nosier over the last several weeks. Probably a bearing was starting to go bad. Mine is an outdoor installation and it ran continuously the whole time. The unit is guaranteed for 5 years. Came pretty close to that!! I suspect that an indoor installation would last much longer than 5 years.

How quiet is the RadonAway RP154 Radon Mitigation Fan?

RadonAway advertises the fan as being "ultra-quiet." Other radon mitigation fan manufacturers list the sound/noise levels of their fans in sones/decibels. How many sones/decibels is "ultra-quiet?" This information is needed for me to make a purchase from Home Depot.

what size is the opening on the unit itself? i understand using an adjustable coupling can be used for a 3 or 4 inch pipe. It would be helpful to know the size of the the unit itself to determine if I need adjustable coupling or not.

RP145 Radon Mitigation Fan is rated 4.7 out of 5 by 88.

Home Depot online pricing was much better than other online retailers and the RP145 is working great! Removed the old dead fan and installed this one myself (I'm pretty inept but this was fairly straightforward electrical rewiring). The only tricky part was that the old fan was placed between two pipes that did not move (coming up from the basement and going out toward the roof), so I had to wedge it out of the rubber gaskets. Fortunately the RP145 was ever-so slightly shorter than the old fan (maybe 1/2 inch) instead of ever-so-slightly taller, so I could wedge it in to the gap and reattach the gaskets. Fired it up and it immediately started working perfectly.

It reduced the radon from a high of 7.8 to .4 well within the EPA regulation. It is easy to install in a 4 inch schedule 40 pipe and wire in an extension cord for the electrical connection. Installing the RP145 is the easy part of radon mitigation, prepping your crawl space or basement is more difficult and time consuming. On the date of this review the RP145 has been installed 18 days. I have no information on the life of this product, so my 5 star rating is based on 18 days of use. I understand there is a five year warranty if a professional does the installation.

This radon fan is super quiet and very effective as verified by a measured reduction in radon concentration via sub-slab suction in a very large basement (approx. 2000 sq feet) from a borderline-safe 4 picocuries per liter to a very acceptable ˂1.7 picocuries per liter. Can't ask for more than that. I'm very pleased with the performance of this fan.

This highly utilized RadonAway radon mitigation fan is not carried in the stores - it must be ordered online. This is was a replacement so my electrical and ducting was already in place. installation and final wiring were a piece of cake.

This fan is mounted in the attic above my sons bedroom and the pipe runs through this closet. I can't even tell it's running unless I feel the pipe.

It is light and gets enough support from the pipes. It generates a lot of suction to pull radon out. I got level of radon dropped substantially (a way more than needed) after turning this on.

The RadonAway RP145 is a replacement unit for one that was 20 years old, but still working w/ a great deal on of noise. The new unit is extremely quiet and after instillation I conducted 2 radon tests to make sure it was doing the job. It is.
