For applications where oil contamination could be extremely costly, such as food industry environment, ACE offers oil-free compressed air solutions containing no lubricating oil at all. Oil-free compressors work entirely through the action of the screws, without the assistance of an oil seal.
Although they sometimes have lower maximum discharge pressure capability, multi-stage oil-free compressors can achieve pressures of over 150 psig, and output volume of over 2000 cubic feet (56.634 cubic meters) per minute (measured at 60°C and atmospheric pressure).
Alongside elimination of contamination, benefits include extended service life through lower speeds and balanced bearing loads, with cooler operating temperatures reduce component wear. No requirement for oil disposal also saves time and money.
