Portable Rotary

Heavy Duty Portable Air Compressors

Many applications are just too big for a standard gas drive truck mount piston air compressor. Whether you are winterizing sprinkler systems or in the construction business, you need higher CFM and 100% duty.

CompressorPros LLC offers portable rotary screw air compressors from 43 to 400 CFM.

Consistent with our overall product offering, we have partnered with top manufacturers to provide a powerful range of air compressors to fit your needs.


ConX Equipment produces unique portable rotary screw compressors that are compact, but very powerful. Starting with model SC40e, (Currently Unavailable) ConX uses a 13 HP Honda engine to give you 43 CFM. Staying with an ultra compact design, ConX builds a 70 CFM and 80 CFM unit that you can fit in the back of an SUV. Both the SC70 and SC80 are powered by a 20 HP Honda Engine giving you the most air from a gasoline powered air compressor.

ConX also offers skid and trailer mount diesel powered air compressors. Model SC90 and SC110 both use a Kubota Diesel and can handle a pavement breaker so you do not have to use 185 CFM compressor for jobs that can be handled with less air. Choose the SC90D and SC110D for skid mount options and SC90DT and SC110DT for tow behind.

EMAX Portable Rotary Screw Air Compressors

EMAX has just introduced a solid range of portable rotary screw air compressors. Also made in Italy, EMAX has options from 70 to 185 CFM.

A lot of applications do not need 185 CFM, so having smaller compressor options that still pack a punch is a huge plus. Model EGS070PT is powered by a 24 HP Kohler gasoline engine. Although compact, the EGS070PT still produces 70 CFM.

To get more air, but still not having to go all the way to a 185, EMAX offers both 90 and 115 CFM units. Powered by a 24 HP Kubota diesel engine, you have the option of skid mount units (EDS090ST and EDS115ST) and tow behind (EDS090TR and EDS115TR).

Finally, EMAX is also offering the construction standard 185 CFM compressor, both skid mount and tow behind. The 45 HP Kubota diesel engine powers a solid Italian airend to get the 185 CFM @ a working pressure of 100 psi. For potential fuel savings, the EDS185ST and EDS185TR have variable speed regulation, so it will speed up and slow down based on demand.
