AS (Air Service System) series

The AS Series provides flow rates from 1 000 to 14 500 l/min. These units are constructed in a sturdy plastic housing. With the wide variety of functions built into the AS Series, these units are ideal for use as universal maintenance units that can prepare compressed air for any application.

Customise your air preparation with Aventics’ modular approach

In addition to the standard functions of filtering, regulating and lubricating, the modular design of these air preparation units means all required functions, such as shut-off, filling, distributor and non-return pneumatic pressure regulator valves, can be easily integrated as a complete air preparation system. Match your filter regulator requirements with ease with these pneumatic products.


All functions, all sizes

The AS Series is used in pneumatic systems around the world, with its range of flow rates and variety of functions making it suitable for universal air maintenance units. With a compact block assembly width and high-quality polymers, the AS is light, yet sturdy.

Additional pressure regulator features
  • Polycarbonate or metal reservoir
  • ATEX approval
  • Contamination display for prefilter and microfilter
  • Easy reservoir release via a bayonet catch
  • Semi or fully automatic condensate drain pneumatic valves
  • Can be individually configured as a maintenance unit
NL Series

 NL Series air maintenance units provide a premium-quality solution for centralised or decentralised compressed air preparation, with solid durable metal housings.

With the NL line, it’s easy to achieve completely customised compressed air preparation, where every component in the series is modular and can be simply combined to achieve the desired function to precisely match to the application requirements.

The system includes 1/8 to 1” connections and comes with filterelement sizes as small as 0.01 µm. It can handle flow rates up to 15 000 l/min, and with nominal air pressure up to 16 bar, provides a high-quality high pressure air regulator.

Functional reliability and a long service life


 The NL Series is engineered to ensure reliable functioning of pneumatic controls over a long service life.

These precise pneumatic air regulator units accurately control the required air pressure, and the differential pressure indicator for the microfilter that lets you know when it is time to replace the filter delivers maximum air distribution system efficiency.

Special micro oil-mist lubricators achieve the finest distribution and a uniform concentration of oil in the air flow to ensure you meet all environmental requirements.
