Compressed air treatment

ALMiG offers the right type of compressed air treatment for every requirement.


Condensate management

ALM-D 10 & 100 condensate drain

Condensate inevitably occurs during the generation of compressed air. The condensate contains oil and dirt particles and can cause corrosion in the compressed air lines and at the consumer if it is not safely discharged.

With ALMiG ALM-D condensate drains you can achieve reliable condensate drainage.

Level-controlled condensate drain ALM-D 10

The ALM-D 10 is a level-controlled condensate drain without compressed air losses for smaller compressed air systems. The ALM-D 10 contains a reliable, direct operated valve with FPM seal and covers pressure ranges from 0 to 16 bar (up to 230 PSI).
With an inlet height of only 74 mm, the ALM-D 10 is a very compact solution with unique installation flexibility and reliability.

Typical application is in refrigeration dryers and filters due to its compact size and low weight of less than 500 grams. The maximum compressor capacity of this trap is 10 m³/min (350 CFM).

Equipment features:

  • Very compact and very light.
  • One model covers all capacities up to 10 m³/min compressor capacity.
  • The inlet height of only 74 mm offers easy installation.
  • The outer position of the valve ensures easy and quick maintenance.
  • Robust, corrosion-resistant aluminium housing.
  • Integrated clever valve self-cleaning mode.
  • Voltage options: 230/115/24 VAC, 24 VDC.
  • Plug connection DIN 43650-B.
  • IP65 protection class.


Electronic level-controlled condensate drain ALM-D 100

The ALM-D 100 removes all types of condensate from compressed air systems up to 100 m³/min without air loss. Due to the air loss-free characteristic, energy savings can be achieved. The compact and robust aluminium housing, the 2/2 way direct operated valve with large passage, alarm NC or NO and the integrated strainer ensure that the ALM-D 100 is the most reliable solution for all compressed air applications.

Equipment features:

  • Compact solution without air loss.
  • Alarm function (NO or NC) integrated as standard.
  • Capacitive level control technology saves compressed air, energy and money.
  • Robust, corrosion-resistant aluminium housing, EP painting.
  • Directly controlled valve ensures reliable condensate drainage.
  • Integrated stainless steel strainer.
  • Voltage options: 230/115/24 VAC, 24 VDC. Plug connection DIN 43650-B.
  • IP65 protection class.

Oil-water separator ALM-OWS

Condensate is formed during the generation of compressed air. This condensate is contaminated with oil, which is drawn in from the ambient air and used for cooling in the compressor stage. Since the contaminated condensate must not be discharged into the sewerage system, it must be separated from the oil.

The ALM-OWS series of oil-water separators reliably removes oil from condensate produced in compressed air systems.
For the safe separation of oil from water, the condensate passes through several separation stages and is filtered through several filter elements.
The oil adsorbing elements combine different types of adsorption technologies to achieve a residual oil content of less than 10 ppm. The first oil adsorbing element has a saturation indicator and offers a visual control, allowing visual monitoring of the separator (even at a distance). The element compositions are always analysed and combined based on the latest, different adsorption technologies.
The final stage contains specially selected activated carbon to separate the remaining impurities.

Equipment features:

  •  Easy and simple exchange of the elements.
  •  Several condensate inlets.
  •  TEST bottle and TEST drain for sampling.
  •  Use of high-performance filter elements.
  •  Simple, quick and clean installation and replacement procedure.
  •  Successful separation of mineral oil, synthetic oil and stable condensate emulsions by the high-performance elements - for highest reliability.
  •  Brass hose connections ensure quick and easy installation and maintenance.
  •  Easy disposal in accordance with environmental regulations.
  •  Any type and design of steam traps can be used.
  •  Compact design and small footprint.

ALM-WS - oil/water separation systems

The ALM-WS prepare compressed air condensates with an average oil content of 5% which makes them too environmentally damaging to be discharged in waste water without treatment. Their purpose is to obtain limit values that are in conformity with permissible discharge values.


  • Operator- and service-friendly
  • Simple, rapid filter change
  • Waste water test kit included in scope of supply
  • Reduced disposal costs
  • Level indicator to monitor filter throughput
  • Heating can be easily retrofitted at any time
  • General building authority approval
