Filters for fluids including compressed air, gases, process liquids

Paul Boughton
The new Filtersoft range of cartridge filters from Hi-line Industries Ltd are claimed to offer savings of up to 75 per cent compared with the cost of other manufacturers products. These savings are achieved, however, without any compromise on build quality, performance or anticipated service life.

Filters can be supplied for use with a wide range of fluids including compressed air, gases, process liquids together with both hydraulic and lubricating oils. They have been designed with energy efficiency in mind, to help companies alleviate the effects of the climate change levy. Typical industries include food and beverage, pharmaceutical, pulp and paper, chemical, semi-conductor and automotive as well as many general industrial and processing operations.

Hi-line are able to cross-reference over 147,000 different cartridge filter elements, covering a wide range of filtration products from a large number of suppliers to this market. Their Filtersoft range combines maximum chemical and thermal compatibility, with availability in a wide range of sizes and end cap materials and configurations to ensure that they can be used as drop-in replacements for most filters.

They can be supplied for particulate removal, vacuum mist elimination, instrument air, coalescing and odour absorption applications. A multistage filtration effect including impaction, direct interception and diffusion is achieved with the ultrafine 100% borosilicate glass microfibers used for the body of the filtration element. The elements are also designed to fit directly into existing filter housings without modifications or the need for special fitting kits, with popular filter element sizes being available from stock.

The proprietary Microflex filter media used in the manufacture of Hi-line products features a tapered-pore structure which ensures 99.99999% particle removal down to 0.01 microns. In many cases, this performance is higher than original equipment specifications and is coupled with high flow rates, good dirt holding potential and low differential pressures to provide long service life.

As well as manufacturing replacement filter cartridges, Hi-line can also supply a range of desiccant and fridge dryers for the treatment of compressed air. In addition, they offer a Total Filter Management (TFM) strategy, designed for supplying all company filtration needs from process chemicals to effluent strainers.
