MER-MADE's rugged fiberglass tanks are a breakthrough in filter manufacture. These long life tanks are designed for 50 psi working pressure in three different diameters and a variety of lengths, with filter areas up to 23.7 square feet.
Filtration:
Filtration is the physical process of removing solids through a substrate. If not eliminated those solids can interfere with and impede the water purifying process. Mer-Made utilizes a multimedia substrate for our sand filters. Two grades of gravel below a top level sand bed provide proven industry-leading water clarity.
All Mer-Made filter Systems are certified by NSF international and ANSI/NSF standard 50 for pool and spa applications.

Filter tanks are manufactured from fiberglass using heavy woven cloth as necessary for strength and have a minimum wall thickness of 0.3″. Filter tanks are designed for 50 psi working pressure with a safety factor of 4 to 1. They are factory tested at 75 psi. The effluent header is designed so that uniform collection of filtered water and distribution of backwash water is provided under the entire media area. The pipe is slotted PVC. The total area of slots in the filter is equal to (4) times the area of the inlet pipe. The orifices in top laterals are equal to (7) times the area of the inlet pipe. The filter tank is provided with 12″ x 16″ fiberglass elliptical manway with gasket, yoke, and bolt cover which is sealed by internal pressure. The filter is designed for a filter rate of up to 14 GPM per square foot of filter area and a backwash rate of 15 GPM per square foot of filter area.
