Superb reliability and simple maintenance save time and money. The patented Anti-frost Valve protects air tools from freezing when the ambient temperature is lower, significantly increasing tool service life.

Mobilair compressors are simple to operate, provide excellent component accessibility, and are easy to maintain. Their enhanced safety features and very low nose levels make them the perfect choice for any job site. Towable models have excellent handling with even weight distribution and feature a torsion bar suspension system. Superior efficiency means you can rum them longer before refueling.
