AS (Air Service System) series – our product family of perfect maintenance units

The four series with a flow rate ranging from 1000 – 14,500 l/min and the variety of functions make the AS series suitable for use as universal maintenance units that can prepare compressed air for any application.
 
The AS family

  • offers top quality
  • has an excellent design
  • can be individually configured as a maintenance unit.

Modular design
In addition to the standard functions of filtering, regulating, and lubricating, the modular design also enables the integration of all specifically required functions, such as shut-off valves, filling valves, distributors, and non-return valves with compact dimensions.
 
All functions, all sizes
Different flow rates and a variety of functions make the AS series suitable for use as universal maintenance units. The block assembly width is very small and high-quality polymers make the maintenance units very light, yet sturdy.
 
The highest standards for filtering, regulating, and lubricating

  • Individual components can be disassembled while installed
  • Subsequent expansion of individual elements
  • Industrial leaders in pressure control
  • Semi or fully-automatic condensate drain valves
  • PC or metal reservoir
  • Smooth polymer surfaces resistant to cleaning, PA or metal protective guards for filters and lubricators
  • ATEX approval
