Mobilair M57 delivers more air

Kaeser’s M57 Mobilair portable compressor is built for rugged use and dependable performance.

The 49-hp M57 delivers 210 cfm at 100 psig, and includes the power-saving Sigma Profile airend as well as an oversized fuel tank to provide more than 10 hours of uninterrupted operation, making the M57 the longest running portable in its class.

The heavy duty 4-cylinder diesel engine with cold-start battery ensures reliable operation, even in the most severe conditions. Kaeser’s proprietary anti-frost thermostatic valve eliminates tool freeze up. The solid steel floor and panel insulation greatly reduce noise levels, and the powder-coated enclosure with gull wing doors provides easy access to all service points as well as the large toolbox. The torsion bar suspension system and oversized tires provide excellent road handling.
