The filter fan assemblies protrude only 6mm outside the enclosure, the closed pore foam filter can be changed from the outside and the units are available in three different sizes: 150 x 150, 250 x 250 and 325 x 325mm. There are five sizes in the family, available with fans operating with voltages from a choice of 12, 24 or 48VDC, 115 or 230VAC or three-phase 400VAC. The air throughput is dependant on the degree of sealing. The smallest unit, the PF2000, when fitted with the 350g/m3 IP54 material, has an air throughput of 56m3/h; with the additional 150g/m3 filter to achieve the IP55 rating, throughput is 36m3/h. The corresponding figures for the most powerful unit in the range, the PF6000, is 625 and 364m3/h respectively. Both the filter fans and the exhaust filters feature the patented Click and Fit installation, which, by doing away with the need for fixings, can save up to 24 minutes assembly time per unit. The complete assembly is simply pressed into the aperture in the enclosure panel from the front; the fixing clamps snap into place to secure the unit. *** Ends: 224 words *** Notes to Editors.
