Portable compressors with generator option

Compressor/generator combination with up to 8.4 m³/min

Powerful, durable and flexible – MOBILAIR portable compressors with generator set from KAESER are true all-rounders. A multitude of equipment options allow these portable compressors to be precisely configured for any application.

From all-rounder to consummate professional: Optionally available with synchronous generators and/or compressed air treatment components, these portable compressors are also offered in various maximum pressure variants, meaning the perfect model is always available, whatever your application may be.

What's more, transporting these powerful all-rounders is a simple and convenient matter. KAESER portable compressors are equipped with lifting eyes as standard; they can also be specified as stationary versions equipped with skids or machine feet, making them the perfect choice for any operating location.

MOBILAIR portable compressors can be used wherever the key requirements are efficiency and durability. These powerful all-rounders excel when working on blasting applications and crash barrier construction. The optional generator transforms these machines into a portable power plant for the whole construction site.

Performance data:

  • Flow rate up to 8.4 m³/min
  • Gauge working pressure up to 14 bar

Your benefits:

  • Compressed air and electrical power
    The generator function eliminates the need for a separate power supply to operate your pneumatic and electrical tools or lighting.
  • Low emissions/EU Stage V
    Minimal emissions values in accordance with the strict provisions of EU Stage V.
  • One for all
    The M59, with its environmentally friendly Hatz engine, is exceedingly versatile. Thanks to a multitude of available options, this compact machine is a true all-rounder when it comes to construction site applications. It features a low-emissions engine, which guarantees exceptionally environmentally friendly operation and is approved for use with HVO100 fossil-free biofuel.

Environmentally friendly and low-emissions

Series models M59, M65 and M82 are certified to EU Directive 2016/1628, Stage V.

Series models M59, M65 and M82 are designed to provide clean air – not just for low emission zones – certified to EU Directive 2016/1628, Stage V. Furthermore, with a diesel particulate filter fitted as standard, these environmentally friendly powerhouses meet the stringent requirements of the Swiss Clean Air Act.

Maximum compressed air availability

Integrated, perfect compressed air treatment
Integrated compressed air aftercooler on the M59.

The compressed air is cooled to 7°C above ambient temperature. The compressed air cooler is installed at an angle, allowing accumulated condensate to drain away easily, whilst the hot exhaust gases from the engine are used to aid condensate evaporation. This prevents the cooler from freezing up as a result of accumulating condensate. Additional air treatment components may need to be installed downstream from the aftercooler and centrifugal separator (e.g. filter combinations for concrete cleaning as per ZTV-ING) in order to achieve compressed air of a specified quality class.

Oil-lubricating or oil-free? – Depending on the application, MOBILAIR machines can be optionally equipped with a tool lubricator to provide oiled compressed air for lubricating air tools, or with a microfilter combination for blasting work requiring technically oil-free compressed air.

Dry compressed air – The plate-type heat exchanger reheats the cooled compressed air using heat from the compressor cooling fluid. This prevents condensation from forming outside the unit when the compressed air cools. The compressed air temperature can easily be adjusted as required from the exterior of the machine.

Pressure and flow rate flexibility

Thanks to pV control, maximum pressure (p) – adjustable in steps of 0.1 bar between 6 and 14 bar – directly influences the maximum possible flow rate (V), thereby providing even greater flexibility in terms of both pressure and flow rate. This feature is particularly beneficial when working with longer hose lines. pV control is fitted as standard on the MOBILAIR M59 and the M65PE.

M58utility for crash barrier construction

This portable powerhouse is designed and optimised for permanent operation from an HGV loading bed and offers excellent accessibility to the control panel, fuel tank and oil level gauge from the front side of the unit. Moreover, with additional options such as adjustable machine feet, tool lubricator and compressed air aftercooler, it can be perfectly adapted to the individual work environment.
A large fuel tank volume of 105 litres allows long shifts of up to ten hours in continuous operation. Forklift pockets in the closed standard base frame ensure safe, dependable manoeuvrability via forklift truck.
