PP String Wound Filter Cartridge

The winding becomes denser from the outside in, providing depth filtration: particles are held throughout the cartridge, extending service life.

Features

High dirt-holding capacity through depth filtration
Graded winding for long service life
Polypropylene yarn and core; chemically resistant
Fits standard 2.5" diameter 10" - 40" housings
Low initial pressure drop, high flow
Economical, easy-to-replace consumable

Applications

Pre-filtration of mains water in residential and commercial buildings
Protection ahead of reverse osmosis (RO) and water treatment units
Well, tank and spring water filtration
Industrial process and cooling water lines

Use: Disposable, not washable

Shut off the water supply and relieve the pressure in the housing.
Open the housing, remove the used cartridge and clean the inside of the housing.
Centre the new cartridge in the housing, check the O-ring and close the housing.
Slowly reopen the water supply and check for leaks.
On first use, flush the line for a few minutes.

String wound cartridges are disposable and must not be washed and reused. Replace the cartridge when the inlet-outlet pressure difference reaches 1 bar, or every 6 months at the latest. Slight foaming may occur on the first flow through a new cartridge; this is normal.
