Automatic self-cleaning water filters
Orival automatic self-cleaning water filters remove micron-size suspended solids, independent of specific gravity, from water in once-through and recirculating systems, such as cooling, process, reclaim, effluent, intake, and wash water. Single filters handle flow rates of up to 12,000 gpm. Units can be banked to handle unlimited flows. The automatic self-cleaning cycle is line-pressure-powered, takes only seconds, and does not interrupt system flow. Installation can be vertical, horizontal, or diagonal in new or existing piping systems. Typical applications include protection of heat exchangers, spray nozzles, instrumentation, pump seals, air compressors, and the environment.
