SCHUMAK Two Stage Air Compressors SDS 03 are high-efficiency reciprocating piston air compressors designed for demanding industrial applications. These compressors feature a two-stage compression system with a built-in back-pressure relief valve that reduces initial motor load and ensures smooth startup.

Key components such as the crankshaft, connecting rod, cylinder, valves, and pistons are precisely engineered for two-stage operation, delivering reliable performance and extended service life. The cylinders are manufactured from special cast iron and equipped with deep radial cooling fins for faster heat dissipation and improved thermal control.

Each cylinder is individually cast, precision-bored, and honed to ensure smooth operation, consistent lubrication, and reduced wear. With low specific power consumption and robust construction, SCHUMAK two stage air compressors offer excellent energy efficiency, durability, and long-term operational reliability.
