Arrow Pnuematics Filter Regulators

Arrow Pneumatics is a manufacture of parts and products for the compressed air industry. At Arrow Pneumatics our business spans from making sintered bronze, FRL's, filtration products, refrigerant air dryers, and regenerative air dryers.  Filter/Regulators are used in air lines that feed a variety of mechanical equipment, including air operated, double diaphragm pumps.


Arrow Pneumatics produces several size air regulators with, from miniature regulators to high flow regulators.  Micro finished brass seat to ensure no reduced pressure creep

  • Reinforced diaphragm for repeated accuracy
  • Minimal pressure drop due to efficient aspiration
  • Three position non-rising adjustment knob; push to lock, pull to adjust, detach to make tamper resistant
  • Relieving style standard
  • Easily panel mounted
  • Tamper-proof cap included
  • High scfm flow due to efficient aspiration

Particulate Filter

Particulate filters remove harmful oil/water condensate, pipe scale, dirt and rust from you compressed air system. This prevents corrosive damage to compressed air equipment and finished products. Typically, particulate filters are installed upstream of regulators to prevent valve failure. They are also used as pre-filters to oil removing and coalescing filters to insure high efficiency and long element life in applications such as paint spraying, instrumentation and pharmaceuticals.

Integral Pulsation Dampener

If a virtually uniform flow is needed, pulsation dampeners in different versions are available. The E-SERIES pumps can be equipped with screwed-on or flanged pulsations dampers, while the CHEMICOR and BIOCOR pump series with an inline pulsation damper.

Barrier Chamber

The ALMATEC barrier chamber system meets high safety requirements. The individual diaphragm is replaced by two diaphragms arranged in tandem with a barrier chamber of conductive PE between them and filled with non-conductive liquid. A change in conductivity of the barrier liquid is detected by sensors and signalled to a controller, which triggers an alarm or disconnects the pump.

Stroke Counting

ALMATEC air-operated diaphragm pumps can be used continuously (24h operation) or intermittently for hours, minutes or for an exact defined number of strokes. To accurately count the strokes a sensor can be installed in the pump's center housing (available as pneumatic version also).

Draining System

The E-SERIES pumps in sizes 15 to 50 are available with a special ALMATEC draining system consisting of a bypass system in the side housings that can be activated easily either via hand-operated valves or pneumatically. In this way, the pump and piping can be drained without having to be dismounted. The amount of cleaning agent and solvent required when changing products is reduced considerably and this greatly reduces environmental pollution. For the pumps of the metal series CHEMICOR another constructive solution is available. Ball lifters - which are turnable by hand - are fitted to the four ball valves. By turning the handles the ball valves are lifted out of their seats.
