The M255 (above) portable compressor from Kaeser Kompressoren is powerful, safe and easy to use. This compact powerhouse delivers variably adjustable pressures between 6 and 14 bar with flow rates up to 25.5 m³/min.
This versatile portable compressor is therefore ideal for applications such as drilling, quarrying or blasting work.
Beneath the enclosure lies a Cummins engine with 210 kW of power, a diesel particulate filter and an SCR system, meaning that the M255 fulfills ‘Stage V’ emission or ‘Tier 4 final’ regulations.
Thanks to the innovative pV control, the operator only has to choose between two pressure levels. The set pressure ‘p’ directly influences the maximum flow rate ‘V’. With a maximum available flow rate of 25.5 m³/min, one and the same system can therefore deliver pressures between 6 and 14 bar. If the application does not require high pressures, then the 10 bar version delivers even more compressed air.
Equipped with a new operating concept featuring a rotary switch and a touch display, operation of the M 255 could not be simpler, even when wearing unwieldy work gloves. Furthermore, the new Sigma Control Mobil 2 (SCM 2) compressor controller allows the machine to be used in conjunction with multiple stationary systems in a compressor station.
The inclusion of lashing eyes as standard and climbing aids to enable safe access to the lifting eye make transportation safe and simple. The road-going version can be towed with a pick-up, for example, since it weighs less than 3.5 tons even when fully equipped, whilst the tandem chassis with overrun brake ensures maximum safety when towing and parking.
A look under the hood reveals various familiar efficiency features, such as the energy-saving fan, or the air filter with safety elements. But there is also something new: the oil separation system uses cartridges that can be screwed on and off quickly and easily to significantly reduce the time needed for maintenance.
There is also security for the system itself. The M255 can be equipped with a modem to allow remote monitoring of the machine’s location and operating data, so that the operator knows where the machine is at all times, how it is operating and what its status is.
The heavy-duty M450 portable compressor was specially-developed to deliver unwavering performance under extreme environmental conditions. With a maximum available flow rate of 48.1 m³/min (1700 cfm) and adjustable pressure between 6 and 14 bar, it also provides exceptional power and versatility. The largest portable compressor in the Mobilair series therefore assures a dependable supply of quality compressed air no matter whether in the desert or in the cold.
This versatile portable compressor is ideal for applications such as drilling, quarrying and blasting work, or can serve as an energy source for mining and tunnel construction sites.
Beneath the hood is an electronically-controlled MTU engine with an output of 2360 kW, meaning that the M450 fulfills ‘Stage IIIA’ emission or ‘Tier 3’ regulations and can handle fuel containing sulphur. Moreover, the combination of a premium efficiency airend featuring flow-optimised Sigma Profile rotors and the energy-saving fan installed as standard ensures exceptionally economical diesel consumption.
Thanks to the innovative pV control, the operator only has to choose between two pressure levels. The set pressure ‘p’ directly influences the maximum flow rate ‘V’. One and the same system can therefore deliver pressures between 6 and 14 bar.
For applications requiring 7 bar, a version delivering up to 8.6 bar is available, for example, with a powerful flow rate of 48.1 m³/min (1700 cfm).
Operation could not be simpler, since the the M450 uses the proven Sigma Control Smart controller, which also indicates when the next scheduled maintenance is due. Following the push-button start, the system runs in unloaded state to ensure a safe cold start in all situations. The display shows the end of the warm-up phase and the system can then be switched to load operation to generate compressed air. Pressure adjustment is also straightforward.
Depending on the application, the system can be equipped with a compressed air aftercooler, or with a microfilter combination for technically oil-free compressed air. With environmental protection in mind, accumulating condensate does not drip out of the system, but is evaporated via the hot exhaust gases.
The M450 is optionally available on a construction site chassis with a steering axle and parking brake, or as a stationary version with skids. The system is equipped as standard with an integrated forklift guide and lifting eyes for ease of transport, which can be safely accessed using climbing aids.
