1. Each candle-like filter element is composed of thousands of thin wafers and compressed tightly by springs. When dirty fluid passes through tiny gaps between wafers, all particles over one micron are trapped on the outside edge of filter elements. Filter efficiency reaches 1-3 micron.
2. Automatically cleaned by a rapid backwash cycle. Use air to blow out particles trapped on elements and then deposit them into a sludge collecting basket.
3. Equipped with oil suction and filtration device in the sludge basket. Therefore, dry sludge is easy to be collected and sold.
4. The replaceable filter elements’ life lasts several years. (Please use recommended circulation oil.)
