Raritan Raw Water Strainer

The Raritan Raw Water Strainer (Model RWS) is a compact, pressure-tested intake protection system designed to safeguard marine engines, generators, air conditioning units, and other equipment that draws raw water from external sources. The unit's clear housing allows operators to visually monitor debris accumulation without disassembly, and its removable #16 mesh screen provides fine filtration of sand, silt, sediment, and organic material that would otherwise damage internal cooling passages and components.

Factory pressure testing ensures reliability across variable operating conditions—critical for vessels, platforms, and remote installations where equipment failure creates safety and operational risk. The durable clear plastic construction resists corrosion from saltwater and brackish environments while remaining lightweight at 2.6 lbs. Installation is straightforward: the unit threads inline with minimal modifications, and routine maintenance involves rinsing or replacing the mesh screen when visual inspection shows debris loading. This low-cost approach to raw water protection extends equipment service life and reduces unplanned downtime by preventing sediment-induced blockages and thermal stress.

The Raritan raw water strainer is standard equipment aboard commercial fishing vessels, naval auxiliaries, offshore platforms, and land-based systems using open-loop cooling. Its simplicity and ease of maintenance make it preferred for high-use applications where filter changes must be quick and accessible. The #16 mesh specification balances flow rate with filtration fineness—coarse enough to avoid excessive pressure drop, fine enough to catch particles that damage seals and bearings in pumps and heat exchangers.
