PSguard® Pariticle Reduction Filter Cartridge

The PSguard® filter cartridge is an absolute rated, pleated polyethersulfone (PES) membrane filter designed to provide greater bacteria and removes particles at high flow rates and extremely low pressure drops. It offers the greatest assurance of filtration performance stability and service life for controlling contaminants in demanding environments. PSguard® Filter media is created by a patented process that produces an outstanding polyethersulfone membrane that is inherently hydrophilic. PSguard® membranes are highly durable.

PSguard® Efficiency

PSguard® filter cartridges combine a high dirt holding capacity, protective abilities and extremely high flow rates, These cartridges are easy to clean for an efficient regeneration if necessary.
