Intake Water Filtration

Intake filters are designed to do the heavy lifting of large or fine solids removal from an incoming water stream so that other polishing post filtration technologies can operate more efficiently and at less cost. Intake water can come from the city, municipality, river, lake or well.

PEP Filters is a globally recognized water filtration company with a rich history of providing fine filtration solutions for industrial cooling, process water treatment, and commercial HVAC cooling tower applications.
