SCHUMAK Two Stage Air Compressor SDS 15 is a high-efficiency reciprocating piston air compressor engineered for demanding industrial applications. This two-stage air compressor is equipped with a back-pressure relief valve that minimizes initial motor torque and ensures smooth, reliable startup.

All major components including the crankshaft, connecting rod, cylinder, valves, and pistons are specially designed for two stage air compressor operation. The heavy-duty cast iron cylinders feature deep radial cooling fins for rapid heat dissipation. Each cylinder is individually cast, precision-bored, and honed to deliver smooth performance, efficient lubrication, low specific power consumption, and long service life.
