Apparatus to protect a radon fan from mechanical failure due to damage from falling objects from within the radon mitigation system

摘要

This apparatus protects a radon fan from damage due to falling water, ice, critters and debris and is installed above the radon fan and protects the fan in several ways.;It is installed just above the radon fan, thus taking advantage of warm “Earth Temperature” air to reduce ice build-up.;Its screen replaces the critter screen often installed at the top of the exhaust pipe where ice is formed. The screen additionally prevents ice and debris from falling into the fan.;The water bypass catches back-flowing water and directs it around the fan.;The access port serves as an opening for testing, observations and cleaning of any debris that is collected by the screen and the access port is sealed with a removable plug. This apparatus protects and extends the life of a radon fan and is made part of the radon mitigation system.
