Castair

D10324HC-S The Castair D10324HC-S is a heavy-duty duplex industrial series air compressor, engineered by Castair, a family-owned Minnesota company since 1991, for superior performance in medium to large shop environments and mobile applications, including HVAC service trucks requiring high air output and redundancy. Featuring dual 5 HP, single-phase, 208-230V Baldor motors, this compressor delivers up to 35.2 CFM at 175 PSI, operating at a slow 758 RPM for quiet performance and extended durability. Its two-stage, dual full cast iron, oil-lubricated pumps ensure robust reliability, making it ideal for heavy-duty industrial air compressor tasks in HVAC installation, automotive repair, manufacturing, and mobile service operations like duct cleaning or construction. The 120-gallon horizontal ASME-certified, powder-coated tank provides substantial air storage and is built for safety and corrosion resistance, perfect for powering high-demand pneumatic tools used in HVAC service, such as impact wrenches, refrigerant recovery systems, and pneumatic drills. Equipped with advanced intake noise silencers, including automotive-type filter/silencers with paper elements, the D10324HC-S significantly reduces operational noise, ensuring a quieter workspace in service trucks or job sites while maintaining clean air intake for optimal efficiency. The V-twin cylinder design in each pump promotes 360-degree cooling for enhanced performance and longevity, supported by precision steel connecting rods, automotive-type rod insert bearings at the crankshaft, and needle bearings at the wrist pin for superior reliability. Key features include tapered roller bearings at both ends of the crankshaft for reduced friction, stainless disc and spring valves offering up to 10 times the lifespan of competitor reed valves for easy maintenance, and pistons with four rings for higher efficiency and minimal oil carry-over. The slow RPM and larger bore/stroke design result in cooler, quieter operation, extending pump life in rugged environments. Rigid metal belt guards, copper discharge, and unloader tubes improve durability and heat dissipation, while an easy-to-read oil sight glass simplifies maintenance. A centrifugal unloader ensures load-less startups, and the duplex design allows operation of one or both pumps, alternating automatically or running together for double the air output, providing redundancy if one pump needs repair. Measuring approximately 72" L x 24" W x 48" H and weighing around 895 lbs, the D10324HC-S is designed for stationary or mobile industrial use, with mounted starters for easy operation. All Castair compressors are built to order, allowing customization for specific needs.
