Industrial Air Compressors

CASTAIR'S heavy duty shop air compressors. Featuring oversized cast iron pumps ran at a slow RPM for quiet operation & long life.

INDUSTRIAL COMPRESSOR SERIES 5-30hp

A robust Castair I518VC1-S heavy-duty industrial air compressor, proudly manufactured by a Minnesota-based company, featuring a high-quality, American-made Baldor motor for reliable performance and an ASME-certified tank ensuring safety and durability, ideal for demanding shop environments.

I518VC1-S
(w/ Aftercooler)
A powerful Castair I15312HC3-S heavy-duty industrial air compressor, crafted by a Minnesota-based company, equipped with a premium, U.S.-made Baldor motor for superior performance and an ASME-certified tank for enhanced safety and longevity, perfect for professional shop applications.
I15312HC3-S
(w/ Aftercooler)
A robust Castair I10312VC2-S heavy-duty industrial air compressor, engineered by a Minnesota-based company for medium to large shops, featuring a premium, U.S.-made Baldor motor for exceptional performance, an ASME-certified, powder-coated tank for safety and durability, and equipped with an intake noise silencer to reduce operational noise, ensuring a quieter and safer work environment. Crafted with a full cast iron pump, steel connecting rods, and tapered roller bearings, this compressor operates at slow RPMs (420–995) for cooler, quieter performance and extended service life, making it ideal for demanding industrial applications. The intake noise silencer, such as the Castair SA100X2M model, features a 1” NPT female inlet, 1” NPT male outlet, and all-steel construction, installing easily between the intake filter and pump to minimize noise, provide cooler and drier intake air, and allow monitoring of unusual compressor sounds.
