The STENHØJ Espholin H-compressor is a twin stage V-unit with an air-cooled inter-cooler between the cylinders. The air is drawn in on the low-pressure side through an efficient air filter, passing through the air-cooled intercooler to the high pressure cylinder to the final working pressure. STENHØJ has manufactured Espholin 30 bar piston compressor in cast iron since the early 1990's. The compressor has a low rotation speed for long life.
