Test Results

Ratings are based on laboratory tests for 10 inch cartridges as per ASTM F795-88 specifications at ambient temperature and 3 gpm (US) water flow rate. Flow rate vs. pressure drop data is based on clean water at an ambient temperature of 25 °C. Results in actual use will be influenced by the type of fluid and contaminant as well as flow rate and temperature.
