Why Is Up-Flow Such A Big Deal?
This product is designed with a patented Up-Flow Technology which prevents the accumulation of air inside the filter housing, keeping the filter operating at 100% efficiency. In a typical competitive multi-cartridge filter, there is a potential for air entrapment. With outlets located below inlets, air travels upward so vents are needed to expel air that can accumulate within the filter vessel during operation. There is also a potential for by-pass. With outlets located below inlets, by-pass can occur as unfiltered liquid drains downward to the sump while the cartridges are removed. This may result in by-pass when the filter is put back into service.
