Dcfairfan radon fan kit

The EPA calls radon the leading cause of lung cancer for non-smokers and the second leading cause of lung cancer for the general population. It describes active subslab suction as the most common and usually the most reliable radon reduction method: a radon vent fan connected to the suction pipes draws radon gas from below the home and releases it into the outdoor air, while creating a negative pressure, or vacuum, beneath the slab. The EPA says the fan must run continuously for the system to work correctly.

A fan kit bundles the fan with the parts that join it to the pipe and show that it is working. The EPA's 1994 Radon Mitigation Standards called for the fan to be installed using removable couplings or flexible connections that can be tightly secured to both the fan and the vent pipe, to make maintenance and replacement easier, and the EPA's consumer guide says every active system needs a warning device, usually a manometer, that alerts you if the system stops working properly.

Sizing is the other half. The EPA's construction guide says the fan's size and air movement capacity should keep the pressure beneath the slab lower than the pressure above it, and, as a general figure for new homes, that a fan moving 100 cubic feet of air per minute at one inch of water column should be sufficient for most applications and that most contractors have found 90-watt in-line fans adequate for most homes. Fan makers that publish airflow at each static pressure let a mitigator check a fan against a house; we found no such table from Dcfairfan.

DCFAIRFAN is a registered US trademark, Reg. No. 7,624,795, owned by Shenzhen Yicheng Environmental Technology Co., Ltd., a limited company organized in China, at an address in Xinzhuang Community on Matian Street, Guangming, Shenzhen. It covers electric fans, ventilating exhaust fans, ventilating fans for industrial purposes, plumbing fittings, namely, couplers, and air-conditioning and ventilation goods, with first use in commerce on March 10, 2024. The record does not mention radon. Dcfairfan has no website, manual, data sheet or rating label we could find, and Radon411 does not use retail listing copy as a source, so the kit's model number, motor, pipe sizes, maximum static pressure, airflow, power draw, supply voltage, speed control and outdoor rating are all not stated by the maker here. With no model name to go by, Radon411 calls it the Dcfairfan radon fan kit.

Two points from the EPA's 1994 standards show what a buyer would want the maker to state: radon vent fans were to be designed or otherwise sealed to reduce the potential for leakage of soil gas from the fan housing, and a fan mounted on the exterior of a building was to be rated for outdoor use or installed in a water tight protective housing. No Dcfairfan document we could read states either for this kit.
