CompAir's oil free piston compressors deliver possible energy savings of up to 20% over comparable technologies. They are reliable, robust, durable and easy to maintain. Beyond the quality of the R-Series, there are several compelling reasons to choose an oil free compressor. There is no risk of oil contamination of products or equipment. Additional installation, energy and maintenance costs for condensate treatment, filter system or compressed air treatment are avoided. The result is a greatly improved carbon footprint.
The R-Series are two-stage, double-acting reciprocating (piston) compressors. Other main benefits are its easy maintenance and comprehensive electronic control. It can be installed in the open or with noise-reduced housing. Being wired ready for connection, the units are easy to install and require no additional foundation.
The design of the double-acting high-performance compressor offers 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. High-quality, robust construction along with excellent efficiency means that payback times are short. With its long economic life cycle, the R-Series can supply affordable compressed air, year after year.
Being wired ready for connection the units are easy to install and require no additional foundation. The R series is water-cooled, with generously dimensioned tubular coolers. The piston and guide rings are made from high-quality materials, with a central guide ring and piston rings above and below for an effective, low-wear seal, eliminating reverse flow losses. The IP55 electric motor has a low rotational speed of 1000 rpm. There are no separate components.
