FWF & HEPA Filter Holding Frames
Type 9

The LongarĀ® Type 9 front withdrawal frame is manufactured in galvanised steel and stainless steel. Their predominant purpose is to house the filter in a solid and safe state to provide an air tight seal with no air by-pass. They are widely used by AHU manufacturers, and building service contractors. Where required the FWF can be installed directly into the building fabric. Larger installations can be created by bolting frames together to create increased face area. The LongarĀ® Type 9 FWF accepts single or pre and secondary filtration by utilising different retaining wires. Frames are supplied with gasket fitted to eliminate air by-pass. Please see schematics for more information. We offer housings from two stages to five stages depending on the level of filtration required.
