The ELF-Series of filters from Omnipure was designed specifically for the higher volume requirements of the food service industry. The ELF (Extra-Large Format) filters have a capacity of up to 20,000 gallons and flow rates of up to 2.0 gal/minute. Engineered as a two piece system, ELF heads are available with or without an auto shut off valve. Replacing the filter body is as easy as a twist of the wrist, no tools needed. The new extended cap version makes ELF's compatible with other existing manifolds on the market. A full array of media and specially designed carbon blocks makes the ELF ideal for use in restaurants, cafes, coffee shops, vending machines, or any point-of-use commercial application. ELF-series comes in a 3.5" diameter, and 10" or 15" lengths.
