Spare filter elements for CHP high-pressure filters

For 100, 250 and 420 bar CHP high-pressure filter and six CHP spare elements

CHP spare elements fit the CHP1, CHP2 and CHP4 high-pressure filters made of nickel-plated carbon steel. The element determines the filtration stage — from the sintered element B to activated carbon A.

One element fits the filters for all three pressures of the same size and stage: for example CHPS-007V fits the CHP1S-007, CHP2S-007, CHP4S-007. The elements are made for 8 filter sizes with G 1/4" to G 2" threads.

The elements are replaced according to the pressure drop or by time; the sintered element B is cleaned. Activated carbon works up to +45 °C.

Elements by size and stage

Each row is a filter size with its thread, each column a stage. The code leads to the product page of the element.

How to find the right element

The element code consists of the housing type, the stage and the size, with the letter V at the end. The CHP1S-007 filter therefore needs the CHPS-007V element: type CHP, stage S, size 007.

The number after the filter type (1, 2 or 4) only determines the working pressure of the housing. The element is the same for all three pressures.

Order of stages

CHP elements lined up in the direction of flow, numbered 1 to 6, with an arrow — In the direction of flow: 1 coarse filter B, 2 basic filter P, 3 dust filter R, 4 fine pre-filter M, 5 microfilter S, 6 activated carbon filter A.

The stages are arranged from coarse to fine in the direction of flow. Each stage protects the finer stages after it, so their elements last longer.

The fine pre-filter M goes before the microfilter S. An S microfilter always goes before activated carbon A — only with it does solid particle class 1 apply.

Element replacement

Elements P, R, M and S are replaced at a pressure drop of 350 mbar, at least once every 12 months. The activated carbon element is replaced every 6 months. The sintered element B is cleaned in an ultrasonic bath or by blowing it out against the direction of flow.

Depressurise the filter before replacing the element. Once a year, also check the housing for visible damage.

Filters

The elements fit the CHP1 filters up to 100 bar, CHP2 filters up to 250 bar, CHP4 filters up to 420 bar. You will find more elements among the Omega Air spare filter elements.

Does the element fit a filter for a different pressure?: Yes. A CHP element of the same stage and size fits the CHP1, CHP2, CHP4 filters.
How do I know which element I need?: By the filter code: type, stage and size. The CHP1S-007 filter takes the CHPS-007V element.
How often should the elements be replaced?: P, R, M and S at a pressure drop of 350 mbar, at least once every 12 months; activated carbon every 6 months. The sintered element B is cleaned.
