MaxFlow – High Flow Pleated Cartridge

MaxFlow High Flow pleated Cartridge Filter ParMax

The DHFPA-serie filter cartridge is designed to allow a high contaminant holding capacity. The specially selected polypropylene and borosilicate glassfiber material provides the unique combination of high flow rate (114m3/h), high dirt holding capacity, low pressure drop, increased surface area at absolute rating of beta 5000 (99.98% removal) and a wide rang of micron ratings (0.5-100 micron).
The unique layered construction combined with a rigid case construction provides security and a high strength to withstand the harsh requirements of the oilfield and process industry. All components are thermally bonded, allowing operations at higher temperature and pressure and make the cartridge compatible with most fluids and additives in the industry. MaxFlow is an excellent replacement for Pall ultipleat and ParMax. For an overview of other replacements click here.
