All fume extraction systems are designed in accordance with BS EN 14175
PF and F’s Fume extraction systems are normally installed in grey uPVC using pre-formed tube and press moulded bends and in-house fabricated sheet materials with all joints fusion welded, or fire retardant polypropylene. (alternative materials are available if required)
Additionally, the uPVC ductwork can be coated with a flame-retardant glass reinforced plastic (4oz tissue wrap) to conform with fire regulations and provide extra rigidity and prevent damage.
Standard fan units are centrifugal type, and driven by a pulley and belt arrangement to give long life with minimal down time, configured for single or three phase electrical supplies. Direct drive and in-line fan units are also available if required.
All fume extraction systems can be provided with attenuation/silencers to
achieve specific noise readings.
HEPA filtration including safe change housings, can also be provided within
the ductwork runs. PF & F can also offer air input and make up sytems to
match the clients requirements.
