The filter unit is suitable for water applications requiring a side stream filtration unit, which removes dirt and debris from the system, maintaining system performance. The unit has a low pressure drop design and requires minimal assembly time, with the choice of inlet and outlet positions. The unit benefits from a non-ferrous reusable stainless steel mesh filter, meaning no replacement filter cartridge costs are required post-purchase. The easy-to-assemble unit only contains 1 magnet, making it simple and easy to clean while still capturing passing ferrous contamination. Antibacterial filtration is not required, because simply adding CORE biocide to the system treats the entire system.
