Filter/Regulator Model 652

  • High flow capacity at low pressure drop
  • Easy replacement of filter element
  • Provides constant output pressure


For optimal performance, Model 652 combines a filter, regulator and flat gauge in one product. The filter will remove any moisture or debris and the regulator provides a controlled and consistent air pressure. Thanks to its compact design, it is a good alternative in applications where space is limited. Model 652, piggyback, manages compressed air systems operating up to 16 bar (232 PSI) inlet pressure. The model features a polycarbonate bowl, easily visible level indicators, locking device and for extended lifetime, a flexible rolling diaphragm.

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 refer to Model 651 and Model 160. Additional air treatment products are available in our air treatment range including preassembled units.
