Palatek 250F200 Rotary Screw Air Compressor 25Hp 230/460V 3Ph 200 Gallon 100CFM. Used, in Good Working Condition, Tested OK. Motor runs full time then compressor kicks in and out as needed. This does not look like it has the controls to shut off motor in automatic. When pressure is high enough the rotary compressor runs at an idle.
Pressure drops then switches back to pumping. Motor is wired for 480V. Will need new motor starter and overload heaters. Not sure on the cfm.
A rotary screw air compressor at 25 hp should do around 105-108 min.
