Available Product Options

CORE MATERIAL

Polypropylene Economical core of choice for most applications in water and corrosives to 200º F. FDA material.
Tin plated steel General purpose metal core for oils, solvents,paints, and other non-FDA applications. For use to 400º F.
304SS For high temperature applications on diluted acids and moderately corrosive fluids. FDA applications. For use to 750º F.
316SS For high temperature applications on strong acids and highly corrosive fluids. FDA applications. For use to 750º F.

 

STRING MATERIAL

Standard polypropylene For concentrated acids and alkalies, strong oxidizing agents, and corrosive fluids and gases. Non-FDA / FDA available - Consult factory. Easily incinerated to trace ash. For use to 200º F.
Fibrillated polypropylene Non-migrating slit film polypropylene free of extractables used in ultra-pure liquids, electron ics, and plating where non-leaching is critical. Chemical resistance is equal to standard polypropylene.
FDA Grade Polypropylene Idealy suited for potable water, Pharmacutical and Food Processing Applications.
Natural cotton For oils, water, paints, organic solvents, alcohols, and petroleum. Non-FDA applications. For use to 300º F.
Bleached cotton Bleached to meet FDA standards for distilled water, beverages, vegetable oils, petroleum, fatty acids, and alcohols. For use to 300º F.
Rayon Fluid compatibility similar to bleached cotton, but with more coarse fiber and less absorbency than cotton. Swells in aqueous solutions. For use to 300º F.
Polyester Chemical resistance similar to polypropylene with high temperature resistance. For use to 350º F
Nylon For special process applications, concentrated alkalies, and hydrocarbons. For use to 300º F.
Fiberglass Available in both standard and baked media. Baking removes all traces of oil sizing, yielding virgin glass fiber. For use to 750º F.
Avaible in raw or heat treated formats.
Ryton Non oxidizing, good for high PH applications even at elevated temperatures. Is chemically resistant with many acids, salt solutions & automotive fluids. Max Temp 425ºF.

Considerations for Efficient Filtration Installation

FilterCor filters are a simple, economical solution to most problems of fluid clean-up. To achieve maxi-mum benefit from this type of filtration, several factors should be considered when selecting the appropriate cartridges and filters.

1) Viscosity of the Fluid Being Filtered:
Very viscous fluids tend to hold particles in suspension, allowing some larger particles through, thereby reducing efficiency. Conversely, gases drop out particles easily and efficiency is increased.

2) Flow Rate High flow rates may reduce efficiency, low rates increase it.

3) Pressure Drop:
Very high pressure drop may slightly compress the element, increasing effiency.
