M20 Mobile Construction Compressor (capacity 2.0 m³/min; working pressure 7 bar)
Rugged, compact construction compressors weighing less than 750 kg
Compact, easy to maintain, and extremely durable—MOBILAIR diesel-powered construction compressors impress not only with their strong performance but also with their wide range of equipment options. This makes these efficient mobile compressors true all-rounders.
The robust construction ensures trouble-free operation at ambient temperatures between -10 and +45 °C. The rotation-sintered PE covers (optional) are impact-resistant and retain their value. The mobile, compact compressors are ideal for heavy-duty applications on construction sites. All model variants are lightweight, weighing less than 750 kg, and are suitable even for smaller towing vehicles.
Their versatility is also evident in their wide range of applications. Whether sandblasting, formwork, or powering soil displacement drills or rotary hammers—these powerhouses won’t let you down. With the optional integrated 6.5-KVA generator, the mobile compressors become a small power plant that supplies compressed air and/or electricity on the construction site, as needed.
Asset Information:
- Capacity up to 2.9 m³/min
- Working pressure up to 14 bar
Your Benefits
- Cool and Clean Compressed Air
The compressed air is cooled to 7 ℃ above ambient temperature. The angled installation of the optional compressed air cooler facilitates the drainage of condensate, which is evaporated using the hot engine exhaust gases. This prevents the cooler from “freezing” due to accumulated condensate. It is possible to achieve specific compressed air qualities by installing additional treatment components after the aftercooler and the cyclone separator. - Durable and indestructible
The version with an impact-resistant polyethylene cap excels in demanding conditions. - Versatile Options
Sophisticated options make the compressors even more versatile. Thanks to compressed air treatment, a hose reel, a hammer compartment, filtration, or a sealed crankcase, they can be perfectly adapted to any application.
No More Freezing of Compressed Air Equipment
The anti-freeze control system for construction compressors precisely adjusts the operating temperature to match the outside temperature. When used in combination with the optional oil mist lubricator, it protects compressed-air tools from freezing and extends their service life.
