Pneumatic Products, Air Treatment (FRL)

FRL System Model 651

  • Complete preassembled units
  • Accurate pressure regulation and high flow capacity
  • Rolling diaphragm for extended service life


CEJN Model 651 FRL system combines a filter, a regulator and a lubricator in a ready-to-use kit, ideal when space is limited. The filter removes any debris and water, the regulator ensures an adequate pressure level and the lubricator enables constant and proportional oil delivery; together they deliver a highly-efficient system and extend the service life of air-powered tools and equipment. They are easy to assemble and maintain and can be top or side-mounted. FRL Model 651 is delivered with a porting block, used to separate lubricated air and non-lubricated air.

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, we recommend Model 652 and Model 160. Additional air preparation products are available in our air treatment range.
