Set of 1 x coarse and 1 x medium density deep profile foams for FX4 / FX5 / FX6 filters. 

Each set will fill one side of the FX canister filter tray. Therefore to fill both sides of an FX tray you will need 2 x sets of these foams. See pictures.

Profile cut for maximum surface area which ensures that maintenance intervals are kept to a minimum and suspended particles are removed most efficiently. Much more effective than standard Fulval flat foams as the initial contact area is approx. 60% more than flat foams.

The foams are slightly too long so trim them to suit (some people like them very tight).

Coarse foam is approx. 15ppi and Medium foam is approx. 30ppi and each foam is 1" (25mm) thick.

These foams have the benefit of grading out the muck as it travels through the foams before rising up to travel down through the central part of the FX trays. Once the length is trimmed they will fit perfectly as shown in the pictures.
