The ÖlofPleat HFW Liquid Series are high flow capacity, high efficiency, inside to outside flow direction liquid filtration elements designed for applications with large flow requirements. They are available in various grades of absolute rated high performance cellulose, cotton, micro-fiberglass, polyester, and polypropylene media with hardware customizable to suit your application. The large diameter, large surface area pleated media cartridges are designed to provide the optimum combination of particle removal efficiency and contaminant holding capability.
This a pleated style technology supported with robust steel, nylon or polypropylene end caps. The filtering media is then attached to the caps and core via thermal bonding or a highly resistant adhesive to prevent any possibility of by-pass. Various options of outer cartridges encasements are also made available to protect the pleat integrity assuring even flow and contaminant distribution across the effective surface area of the filter cartridge.
Features
- This filter element is designed is to provide absolute rated efficiencies (to βeta 5000) without compromising the element service life.
- Selected filtration media with exceptional holding properties, but comparatively low flow resistance.
- Is economical in service life while being operator friendly.
- Due to the inside to outside flow direction, the positive sealing of this cartridge does not require individual sealing assemblies for each cartridge.
- This large diameter can process higher flow rates with fewer elements allowing you to use fewer filters per housing.
- This element reduces downtime during replacement.
- Additional advantages of the filter is the wide variety of medias to suit each individual process.
- It comes in 100% Polypropylene making incineration an option for disposal.
