Similar to the recirculatory filtration cabinets but instead of recirculating the air the cabinets exhaust the fumes to the atmosphere via a flexi-duct.
The centrifugal blower extracts the air via a three-stage particulate filter. Large particulates (>5um) are filtered out and fine particulates (<5um) together with odours, gases and vapours are exhausted to the atmosphere.
The flexi-duct can be fixed to a standard domestic vent or simply placed through a partially open window. The A2 cabinet comes with one 100mm x 2m duct, the A1 with two ducts and a "Y" piece enabling both ducts to be placed through one vent. The A2 size also has a carry handle to aid with portability. Dimensions are the same as the A1 and A2 recirculatory filtration cabinets.
Noise level: A1 60dB, A2 58dB.
Package includes: filter unit with fan, hood enclosure, 2m flexi duct, 1 x particulate filter, power lead and information booklet.
