Lubricator Model 652

  • Refillable under pressure
  • Constant oil flow for reliable lubrication
  • High flow capacity


Lubricators are necessary if you want to extend service life, maintain peak performance and reduce wear and tear on tools and machines powered by compressed air. CEJN Model 652 for working pressures of up to 10 bar (145 PSI) is one of our most popular lubricators. Model 652 allows for proportional oil delivery, adjusted by a lockable oil-setting knob. 360-degree visibility of oil flow is possible thanks to the transparent glass. To achieve optimum effect with oil lubricators, CEJN recommends that you always install lubricators close to the application. No tools are needed for adjustment.

CEJN lubricators start to lubricate at very low flow. Recommended lubrication oil is 199031580 (1 L) and 199031581 (5 L).

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 smaller and larger sizes, we recommend Model 651 and Model 160. Additional air preparation products are available in our air treatment range, including preassembled units.
