The Mayfair is a cartridge type centrifugal extractor fan. It is fitted with a maintenance free 
rubber mounted motor. The cartridge system permits the fan to be removed from the wall or 
ceiling without disturbing the ductile wiring or wall fittings. The facility greatly simplifies main-
tenance and cleaning procedures.

On new build and renovation projects the Mayfair 2000 fan permits all the installation work 
to be carried out in advance of the fan being fitted, thereby reducing the possibility of theft 
or damage. The Mayfair 2000 range is available with a wider range of features than any other 
extractor fan. It is a high quality product and will give many years of reliable service.
