Highest-level filter material and processing

Quality

Hengst has a many design solutions as there are filter materials and different ways to process them. Hengst also has the advantage of using state-of-the-art methods. The goal of all its development activities is to find the optimum solution for every application in terms of function and economy. An optimal pleat geometry achieved by embossed spacers or adhesive beads applied online or stabilization by polyester bands, expanded metal, perforated plates or plastic mesh round out the quality program.

Optimum selection

Material

Selecting the optimum filter media takes more than just long years of experience. It also requires state-of-the-art technology. For example, long-term dust tests are conducted to test the suitability of the media in accordance with VDI 3926 (FIXME LINK). These tests under “real-life” conditions are performed in four phases, and the differential pressure and... More »

State-of-the-art manufacturing technologies

Processing

Hengst filter materials are selected on the basis of their processing characteristics and the planned fabrication of the filter element. State-of-the-art manufacturing technologies are used to ensure gentle and uniform processing, which above all guarantee an optimum spacing of the pleats, which in turn guarantees effective cleaning down to the bottom of the...
