2901207950 Coalescing Line Filter Element Kit for Compressed Air Treatment

Product Introduction

Clean, dry-grade air downstream starts at the coalescing element, not at the dryer alone. 2901207950 is Atlas Copco's filter kit UD7+ for air treatment equipment, using oil coalescence media to pull liquid oil, fine oil aerosols, wet dust, and entrained water droplets out of the compressed air stream . The UD+ 2-in-1 concept combines general-purpose and high-efficiency coalescing stages in a single cartridge, which keeps pressure loss lower while protecting valves, dryers, pneumatic tools, and production lines .

A loaded element drives differential pressure up and lets oil mist travel farther into the system. Replace on the service indicator or scheduled interval, and check the housing seal face before fitting. Post-2021 UD7+ housings use the curved top inlet profile; confirm the housing generation and connection style so the element seats correctly . Drain the bowl, fit the supplied seals, and recheck for leaks after run-in.

Match the element to the UD7+ housing and machine serial before dispatch. Service life is commonly referenced around 8000 hours or annual change, but intake oil load, humidity, and pre-separation condition still decide real life . Also called UD+ filter element, line filter cartridge, coalescing filter kit.
