Oil free 2 stage piston compressor OPC 7 & 10 bar.
Oil free two stage piston compressor range from 7,7 to 54,5 m³/min ( 6 to 15 bar possibilities on request)
The OPC air compressor solution is a heavy duty, low speed, two stages, oil free, water cooled, reciprocating unit with an “L” cylinder design.
The 6-15 bar oil free piston compressor is mounted on a base plate equipped with anti-vibration mountings and includes:
Electric motor and V-belt transmission, Intercooler between the stages and after-cooler,
The control cabinet with microprocessor is installed adjacent to the base plate. Compressor base-plate with anti-vibration mounts.
No special concrete foundation block is required, resulting from the use of anti-vibration mountings. Easy and quick installation.
2 stage ‘L shape’ cylinder compressor:
