This client required a number of Reverse Jet Filters for use on Vacuum Conveying systems for handling various materials.

The pneumatic blower set were positioned on the clean side of the filters, so they had to be designed to handle a suction of ­ - 0.75 barG.

This was achieved by constructing circular filters with pressed steel domed tops, stiffened door openings and curved doors.

Due to the explosive nature of the dusts being handled, the filters were fitted with ‘Fike’ explosion relief panels.

The filter bags were 1200 mm long x 114 mm dia. Gore-Tex® PTFE membrane/polyester needlefelt with silicone ring seals and PTFE seam-sealing of stitching, and they were arranged horizontally in the filter.

In all 7-off filters were supplied, varying in effective cloth filtration areas of 8.8 m2, 11.0 m2 and 13,2 m2.
