This high-performance, two-stage system was designed specifically for cost-effective, high volume applications. This system is engineered in a two-piece configuration with a permanent head and a bayonet style replaceable polypropylene body. This helps to reduce cost as simple body replacement is cheaper than replacing the entire filter apparatus. Replacement is fast and easy. The body is quickly detached from the head with the twist of a wrist, no tool required. All filter bodies are made with virgin, high-impact polypropylene which is especially ideal for use in applications where sanitary conditions are required. All materials of construction are NSF and/or FDA approved.
