FilterPro exclusive double thickness deep profile foams which have a huge contact surface area compared to flat foams or standard 'bumpy' foams. A deeper profile results in better trapping of dirt and extended cleaning intervals.

Coarse, Medium and Fine foams will make a very effective mechanical zone in your filter. Coarse and Medium are approx. 1" (50mm) thick and Fine pad is approx. 1.25" (32mm) thick. Use in any suitable filter so water hits them in this order:

Coarse, Medium then Fine

That way the dirt particles in water will be filtered out using a graded system which will be most effective and will increase intervals between maintenance. 

Foams are 11" x 17" x 2" (430mm x 280mm x 50mm) 

Coarse foam is approx. 15ppi and medium foam is approx. 30ppi

Fine pad is approx. 1.25" (32mm) thick
