The Ariel JG / JGA
Small Line
JG / JGA
The JG and JGA are medium-sized, driver-rated separable reciprocating compressors utilized in gas gathering, fuel-gas boosting, underbalanced drilling, and CNG applications.
The JG, first introduced in 1966, was Ariel's entry into the domestic reciprocating compressor market. The first 150 frames built were JG/2 and JG/4 and is still Ariel's smallest compressor available in a four-throw configuration. The JGA offers modern gas lift capabilities as shale well production increase in volume.

Innovative Cylinders
Ariel produces versatile cylinders that can be utilized over wide pressure ranges without compromise by using valves that effectively balance reliability and performance. For each compressor frame size, Ariel's lineup of cylinders can fully utilize that frame's horsepower and rod load capabilities. Cylinders can be combined in hundreds of different configurations to deliver the precise volume and pressure of gas required.
Ariel 7 Performance Software is used by Ariel engineers and industry experts to model and design compressor configurations for their specific application. All of our cylinder designs, past and present, can be accessed to duplicate your existing compressor operations or design a new build.
