what an improvement to the heavy industrial screw/centrifuge's compressors normaly found in chiller's

A oiless compressor with no crankshaft bearing's and only 2 amp start up and still produce's the same if not better capacity

save's calling out a heavy lifting team to replace a compressor - most can lift them easily on there own

i have service and technical manuals in pdf if anyone is interested i can email them across
