POWER SYSTEM Series PS-AS DV OIL LESS air cooled two stage packaged compressed air system, providing oil free compressed air and fitted with variable speed drive for maximum energy efficiency.
The PS -AS OIL LESS air cooled series incorporates our advanced OIL LESS two stage rotary screw compressor which features advanced ULTRACOAT surface treatment to the compressors rotors providing absolute protection against wear and corrosion. The compressor element is fitted with advanced low friction bearings which are oversized to easily accommodate axial and radial loading under all operating conditions. The oil less characteristics are fully protected by the use of a stainless steel labyrinth seal system that prevents any ingress of contamination in to the compression process.
The PS -AS OIL LESS DV variable speed series arrives with all controls and accessories included and assembled in to a fully sound-proofed cabinet ready for an immediate and convenient installation. The PS-AS oil less DV range offers all the characteristics, proven reliability and durability of the fixed speed direct drive version with the addition of speed regulation control which means that the generation of compressed air is regulated during operation, so that it precisely matches the demand from the network. This level of control delivers real advantages in terms of saving energy. Because the output of the compressor is regulated according to demand, you consume a proportional amount of energy. The energy wastage due to; off-load operation, venting down and over pressure generation are all avoided.
Typical energy savings represent 20-25% or more, when compared to fixed speed compressors.
