Extraction Filter Units

Pleated cartridge filter elements were originally designed and developed for use as truck air intake filters. The media was very simple folded and pleated paper and they served that purpose very well. In the mid 1980’s the dust control industry recognised their potential use for low dust loaded non arduous dust collector applications and they were soon widely applied in the foundry industry on shot blasting applications and the like.

Extraction Filter UnitThe wider application of cartridge filters in the 1990’s forced the development of sophisticated technical medias to allow the design to be applied to a much wider range of duties. Spun polyester and PTFE laminated felts enabled the use of these filters in the food and pharmaceuticals industries and these units are now developed to a point where they offer a very low cost solution to a very wide range of dust control applications.

The development of downward airflow designs and inclined media element configurations resolved the issue of dust retention on the outer surface of the media. It also enabled more compact filter design and enhanced cleaning efficiency as every element is cleaned by it’s own pulse valve instead of rows of elements cleaned by a jet pipe arrangement.

The Cavendish Filters Reverse Jet Cartridge Filter employs state of the art media options and a top line venturi assisted cleaning system in a robust heavy duty housing at very competitive prices.
