Abstract
A radon exhaust system comprising an exhaust side with a vent housing, a diagnostic bypass filter apparatus providing observation windows, a removable observation window, internal ice and object filter, internal ribbon flow indicators, internal water gutter with drain spout, an exhaust fan and a suction side coupled together to form a conduit through which gaseous fluid may be conveyed. The diagnostic bypass filter apparatus provides an enlarged elliptical air passage bulge and angular bend configuration having three observation windows, a fourth removable observation window, an internal ice and object filter, ribbon flow indicators, and an internal water gutter with drain spout for providing protection of the exhaust fan from falling ice, water and objects and visual inspection for flow in the exhaust system and access to the filter for cleaning.
