Pneumatic Products, Air Treatment (FRL)

FRL Systems Model 653

  • Ready-to-use air-treatment system
  • Accurate pressure regulation and high flow capacity
  • Rolling diaphragm for extended service life


Model 653 combines a filter, a regulator and a lubricator in a preassembled air-treatment kit. 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 provide you with clean air and an efficient system that will extend the service life of air-powered tools and equipment. This combo can be top- or side-mounted, and is easy to assemble and maintain. The system is delivered with porting blocks, which are used to separate lubricated from non-lubricated air. Application: Virtually every industry, e.g. manufacturing, food, process, carpentry, paper mill etc., rely on compressed air as energy source. In a shared compressed air network, with many outlets and an extensive pipe system, air preparation units are especially important.


For smaller sizes we recommend Model 651 and Model 652. Additional air preparation products are available in our air treatment range.
