Washable Pre Panel Filter

Robust construction
Maximum effective media area
Sizes to suit most applications
Specifications:
The filter frame will be of "U"-Channel formation. Material shall be 0.5mm thick galvanised steel. The edges shall be doubled returned for extra strength and so provide a smooth edge thus preventing injury to personnel. The filter shall be able to withstand at least 6 cleanings under normal conditions by either water washing or air cleaning. The media shall be supported on both sides by galvanised wire grid. Thus Ensuring stability and pleats remaining open to allow maximum dust holding and ease of cleaning.
Application:
The WP88 cleanable extended surface panel filter range was locally developed by FIBATRON as a one-stage filter to eliminate the use of low efficiency pad or roll type filters as well as certain low efficiency pocket filters. WP88 filters are used extensively in office blocks, hotels factories research institutions and in general ventilation applications. WP88 filters are locally manufactured in various sizes and are easily fitted into most type if filter installations. The Type S slide-on range of retainer clips are available from FIBATRON for easy upgrading of existing installations. As no holes need to be drilled, fitting is done within seconds.
Installation:
WP88 cleanable extended surface filters are widely used in built-up flat or "V" shaped filter banks as well as in side-access systems which have a 25mm, 50mm, or 100mm standard slide-in filter track.
