Pneumatic Products, Air Treatment (FRL)

Filter Model 651

  • Efficiently removes any airborne solids or moisture
  • Manual/Semi-automatic drain as standard
  • Easy replacement of filter element


As air cools after a compression cycle, moisture collects in the system, potentially causing pneumatic equipment to corrode or become slow, resulting in downtime. We offer CEJN filter Model 651 in our air treatment units. It has a high flow capacity and can withstand up to 16 bar (232 PSI) inlet pressure, efficiently removing any airborne solids. Model 651 includes a polycarbonate bowl, easily visible level indicators and a compact modular design. Choose from filters with a filtration capacity of between 0.01 and 25 μm.

Application: Virtually every industry, e.g. manufacturing, food, processing, carpentry, paper mills, etc., relies on compressed air as an energy source. In a shared compressed air network, with numerous outlets and an extensive pipework system, air preparation units are especially important.


For larger sizes refer to Model 652 and Model 160. Additional air preparation products are available in our air treatment range, including preassembled units.
