Filter/Regulators Model 653

  • Removes water/moisture efficiently
  • High-flow capacity at low pressure drop
  • Provides a constant output pressure
  • Easy replacement of filter element


The Model 653 is a filter/regulator and flat gauge combined. It efficiently removes any moisture and withstands compressed-air systems operating up to 174 PSI (12 bar) inlet pressure. It has a compact design that makes it suitable for applications involving limited space. The model features a polycarbonate bowl, easily visible level indicators, a flexible rolling diaphragm for an extended life and a locking device. Applications: Virtually every industry, e.g. manufacturing, food, processing, carpentry and paper mills, 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 sizes please see Model 651 and Model 652. Additional air treatment products, including pre-assembled units, are available in our air treatment range.
