  • Radon exhaust system with internial gaseous fluid fan within diagnostic bypass filter fan apparatus
    Patent number: 9605869
    Abstract: A radon exhaust system comprising a cylindrical shaped vent housing, diagnostic filter fan housing, inline fan with redirecting vanes, ice filter, observation windows, access opening and closure cap, air flow indicators, water gutter, drain spout and an enlarged elliptical bulge area for additional air passage through the fan housing. The inline fan, located within the elliptical bulge, pumps radon laced air into redirecting vanes, which directs same air through exhaust side and out through expanded exhaust openings of the vent housing. Additionally, redirecting vanes protect the fan from falling ice which may be formed on the ice filter located above the fan. Water is prevented from entering the fan by a water gutter and drain. Observation windows allow visual interior monitoring without entering the fan housing. An access opening with closure cap allows interior maintenance, testing and off venting. These embodiments combine to protect radon systems from damage.
