Portable Compressor


The Mobilair™ M58 Utility rotary screw compressor is designed for cross mounting on service vehicles. It delivers 210 cfm at 100 psig and is ideal for public works, utility, and other field work vehicles.


The M58 Utility is very compact. It has both long and short side forklift slots as well as a single-point lifting bail for easy mounting/dismounting. The eye-level, curb side instrument panel features an easy to operate Sigma Control Smart electronic controller with protective metal cover. Another important feature is the large 28 gallon fuel tank that provides extended operation – up to 10 full hours!


A heavy-duty 4-cylinder engine direct coupled to our energy saving Sigma Profile™ airend produces more air with less horsepower. A high capacity cold start battery ensures reliable operation even under extreme conditions. The M58 Utility’s rugged steel cabinet is powder-coated and built to take the harshest conditions while protecting the machine from dirt, water, and other contaminants. The engine and compressor have separate inlet filters with maintenance indicators. This protection, combined with a high efficiency cooling system, allows the unit to operate in ambient temperatures up to 122°F.
