We are offering booster compressor.booster applicationscompressed air systems in industrial and commercial facilities are generally designed for pressures of 90 to 100psig . However, some special applications such as moulding, printing, and leak testing require higher pressures.Petall booster compressors increase air system pressure to a working pressure of 580psig and to a maximum of 650psig. These reliable units are compact, quiet, and offer an economical alternative to designing the main compressed air system for high pressure. Now you simply install a petall booster compressor to increase the pressure of the existing compressed air where it is needed.
