Traditional Ducted Fume Cupboards provide Operator Safety by taking contaminated air away from the Operator through a system of ducts and discharge fans. The fans are usually mounted externally and the ducts often routed internally sometimes through tortuous routes.

Felcon Ducted Fume Cupboards provide a safe alternative to conventional fume hoods in many applications, without the additional cost of extraction ductwork and fans. In addition the recirculatory characteristics of the air flow avoid the cost of reheating supply air back into the laboratory, which is very important when designing facilities for on-going running costs. Furthermore external environmental protection is afforded since contaminated air is not being dumped into the environment.

The Felcon Ductless Fume Cupboards provides Operator Protection without the need for such ductwork and fans. Instead it incorporates its own fan and filtration system utilising Activated Carbon Filters as its primary filtration medium. The filtered air, which is also filtered for particulate is then routed back into the room or laboratory in which the unit stands.

Felcon Ductless Fume cupboards have the following advantages over ducted versions;
