OASE's Individual Module houses the pump in gravity fed systems and provides space for additional filtration. The two baskets in the flow area can be filled with up to 8 liters/488 cubic inches of Hel-X filter media for additional filtration capacity (sold separately). The Modules allow easy adaptation of the filter system to meet any design requirement. The integrated slide valve on the bottom allows the filter to be easily drained for cleaning or winterization. All Gravity-fed systems must be installed at pond level, typically in an underground vault, and accept dirty pond water through bottom drains or skimmers. The modular systems can be expanded with multiple modules to accommodate any size pond but always end with an Individual Module housing the pump that returns clean water back to the pond. The ProfiClear Individual Module has two 180mm inlets and two DN 110 outlets that require 4” rubber couplings and two 2” adapters. It has a minimum flow fo 2,640 GPH and a maximum flow of 8,700 GPH with a waste discharge outlet of DN 75. Its dimensions are 32.75”L x 26.75”W x 32.25”H and has a 3-year warranty.
