Exodraft RSVG Chimney Fans

RSVG chimney fans are specially designed to work with heating appliances burning gas and oil. The fans have a built-in fail-safe system consisting of a pressure differential switch and a flow measuring system. The fail-safe system complies with BS 5440: 1990 Part 1 and BS 6644: 1991.

RSVG chimney fans are normally installed on top of the chimney where the vertical discharge column prevents a plume of gas flowing down the outside of the chimney and thereby complies with the Clean Air Act. RSVG fans can also be wall mounted.
