CF Series
Comet centrifugal fans are primarily intended for critical duties requiring high reliability and guaranteed performance.
The various Series, which draw on Comet’s extensive know-how in the design and manufacture of dedicated fans, have been developed to meet the requirements of specific applications and are all characterised by high compactness and versatility, with extensive customisation options.
The impellers of Comet centrifugal fans can be fitted with straight, curved or aerofoil-profile blades, and can be made from carbon steel, stainless steel or aluminium, so that the most suitable solution is always available to meet a wide range of environmental, mechanical or noise-related requirements.
In addition to the fan itself, Comet is able to supply a wide range of accessories and installation solutions, including filters, shock absorbers, enclosures and soundproofing systems.
Fans used in the marine sector ensure ventilation and cooling in engine rooms, garages, technical spaces, holds, galleys and heat recovery systems, improving safety, efficiency and comfort on board, while preventing fires and keeping cargo fresh.
