The PXF Floor Standing Chemical Gas Extraction Unit is designed predominantly for chemical gas suppression systems requiring smoke and chemical agent extraction. As the chemical gases’ mass causes them to sink, the inlet box is mounted either on the floor or within a floor void to maximise agent extraction efficiency. The duct can be cut to required length and installed horizontally or vertically. The PXF range of chemical gas extract units provides GAS EXTRACTION ONLY as per FIA guidance 01-02-2012. An additional SHX-UN universal pressure relief vent or DUX two-way pressure relief vent is required for fresh air make-up and pressure relief.
