Ro-Flo’s high pressure rotary sliding vane gas compressors are suitable for a wide variety of applications. Years of experience in this industry has made Ro-Flo the top choice for gas compression. The world’s largest oil and gas companies trust Ro-Flo compressors for their dependability, longevity and superior performance. Ro-Flo high pressure gas compressors excel in handling acid, sour, and wet gases. The high pressure models have a 7:1 pressure ratio capability and can be used as a stand alone unit, or coupled to a low pressure model and used as a second stage of compression. The high pressure models come standard with a double shaft extension making it suitable for a drive-thru unit in the two-stage arrangement. Ro-Flo’s high pressure gas compressors have a maximum allowable working pressure of 150 psig (10.2 barg) and a maximum allowable operating temperature of 350ºF (176ºC).

Ro-Flo’s low and high pressure models are flow-matched to enable two-stages of compression utilizing a single drive. The compressors are coupled together and then coupled to a drive, with both stages operating at the same speed. Variations on this standard setup include independent drives and Ro-Flo® models specifically selected to handle dissimilar flow requirements at different speeds. An intercooler and knockout vessel are typically required inter-stage to remove the heat of compression and any free liquids from the gas stream. When Ro-Flo’s are configured as two stage systems for compression applications, they can produce gas discharge pressures as high as 200 psig (13.6 barg). In vacuum operation Ro-Flo’s achieve vacuum levels as low as 0.7 psia (5 kPa absolute).
