The Filtreau 70 Micron Hi Flow Spare Drum Screen is compatible with all of the Filtreau Filtration Systems - HF30, Combi Next. Combi 2, Combi AFTER, PF20, AEM.

The difference between the Standard replacement screen and the Hi Flow screen is that the slots in the Hi flow screen are roughly twice the size allowing more flow through them. This does mean there is ultimately less plastic framing on the hi flow screens.
Both the standard and Hi Flow screens are 70 micron screens.

Special note: When installing the replacement screen it is advisable to store it in a warm place or near to a radiator (not against the radiator) to ensure it is pliable enough to bend around the drum structure. If stored in a cold place ie shed prior to install it is likely to snap when installing because the plastic will become brittle.
