Whether the OASE modular filtration system is operated as a gravity fed filter in the ground or as a pump fed version. The Proficlear M1 pump chamber ensures the correct positioning of the filtration pump:
For reducing pressure losses
For safe set-up in swimming ponds in compliance with standards
For simple maintenance and over wintering
For protection against excessive sludge
Two inputs for connecting to the bottom drain and skimmer.
On the Base there is a sediment chamber for debris which leaves the pump chamber via the sludge drain.
