Fan enclosures should be addressed with meticulous detailing. AS 1668 and other recognised Standards require the ‘full system’, not just the sheet metal ductwork, to be Fire Isolated. This means that the fan, as well as the motor should be Fire Isolated. LAF have systems which have been Tested and approved by the CSIRO to provide large (2.4 m x 5 m x 3.6 m high) enclosures with up to 240/240/240 FRL.

Services (Actuators, motor drives, smoke detectors, etc) to be attached to Fire Rated Ductwork can remain in full view and at the same time be Fire Isolated. LAF’s tested systems include for the provisions of inspection enclosures fitted with proprietary intumescing grills to achieve a 2 Hr FRL. The
