Non lubricated air compressor Ingersoll-Rand gives you packaged ESVH units that are simple, easy and quick to hook up. And they take less floor space, thanks to their compact design. The ESVH's low power consumption makes a big difference in your energy bills. Lube oil is conserved as well, thanks to the sealed crankcase construction, & low frame oil capacities because oil is used for frame lubrication only. A separate cylinder lubricator reservoir is provided on lubricated units.
