Divers Supply's 1250 three-stage filtration system is composed of two cintered bronze particulate filter elements (40 and 5 micron) followed by and oil removal filter element.
The filter canisters are black, powder-coated, die-cast aluminum and have manual drains. The full frame is designed to physically protect the system (canisters, plumbing and pressure gauge) as well as provide stability.
Need a 3-stage filtration system without the frame for easy hard plumbed mounting? See part number 1250 NO FRAME. Want only 2-stage filtration? See part numbers 1000 and 1000 NO FRAME.
