Description
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. |
 |
RSVG chimney fans are used with heating appliances and provide a
controllable negative pressure along the full length of the flue and
chimney. The fans guarantee optimum chimney draught irrespective of the
placing, dimensions or height of the chimney which is beneficial to new
or existing installations.
The chimney fans offer capacities which will cover domestic
appliances up to multi-boiler
installations with a heat output up to 1MW.
Construction
RSVG chimney fans are constructed of corrosion resistant cast aluminium
and are supplied in grey, painted finish.
The
fans have a mesh safety guard of stainless steel covering the vertical discharge.
The fans are supplied with a backward curved impeller, which gives high
fan efficiency.
The fans are fitted with an entirely closed, asynchronous motor with
ball bearings sealed for life.
The built-in pressure switch on the chimney fan is wired to the
appropriate control unit which supervises the fail-safe function. In
case of insufficient chimney draught, the heating appliance will be shut
down.
The fans are supplied with a 2 year
warranty.
