Gas Powered Air Compressors by Cast Air

A gas powered air compressor from Cast Air gives you full shop-grade output wherever the job takes you — no extension cord, no generator tap, no compromises. Built in Spicer, Minnesota since 1991, every Cast Air unit is constructed with cast iron cylinders and components that hold up to daily production use. The Honda GX engine lineup powering these units is well-established in the trades for a reason: consistent cold starts, low oil consumption, and a parts/service network that runs from rural farm supply stores to urban dealers.

Several Cast Air gas models run as true 3-in-1 units — compressor, generator, and welder in a single portable frame. For contractors juggling tight site logistics, that means one piece of equipment handles compressed air for impact tools, 120V power for site lighting or chargers, and stick welding for quick metal work. Tank configurations vary across the lineup, so match the tank size to your typical duty cycle and runtime needs.

These units are built for independent shops running remote service calls, fleet maintenance crews, farm operations, and construction contractors who need reliable air without wall power. If you're outfitting a fixed bay or need a corded portable, check our contractor electric portable collection for those options.
