These are used to remove liquid particles from gas streams. As the gas flow through the torturers path towards to center many small liquid particles collide with filter fiber and other small liquid particles to form larger particles. Standard nominal micron size for these elements are 0.3 microns. Pleated cylindrical construction of micro fiberglass coalescing media provide longer and durable element life. Polyester drainage layer is used to improve the drainage of liquid droplets.7 Sizes available: 2.5”, 4.5”, 5.5” 6” OD, Lengths 18”, 36”, 29.31”, 36.25” 37.31”.
