R-series-CompAir-Kolben-BMW-039-Retusche_4cThe design of the double-acting high-performance piston compressor brings about a big reduction in electrical input power, at both full and half load. Rapid switching from full load to half load and back again ensures a flexible response to compressed air demand and a low pressure difference in the network. At the same time off-load losses are minimised, at just 8-9% of generating capacity in the case of piston compressors. The significant energy savings result from the low input power at full load, the narrow pressure band and the low off-load losses.

Being wired ready for connection the units are easy to install and require no additional foundation.
