Arial JG/4 Reciprocating Gas Compressor Overview

The JG and JGA are medium-sized, driver-rated separable reciprocating compressors utilized in gas gathering, fuel-gas boosting, underbalanced drilling and CNG applications.

Full Pressure Lubrication:  A frame-driven lube oil pump provides cooled oil through a full-flow oil filter to all moving parts in the frame. A divider-block system supplies metered oil to cylinder bores and rod packings.

High-Strength Bolting:  Durable Grade 8 bolting on all loaded joints combined with specially designed fatigue-fighting bolts on all valve caps ensure ultimate holding strength.

Rigid Connecting Rods:  The JG/JGA compressors feature durable connecting rods manufactured from forged steel with 4 bolts and a heavy-duty “I” section.

Rugged Crossheads:  One-piece, long-life crossheads with hardened, ground steel crosshead pins and direct, full-pressure lubrication at the top and bottom for minimum wear.

Innovative Cylinders:  Ariel’s single and double-acting non-cooled cylinders eliminate the cost and maintenance associated with water cooling.

Durable Pistons and Rods:  JG/JGA compressors feature wear-resistant ductile or gray iron pistons and precision-ground alloy steel piston rods with locking crosshead nuts. Rolled threads are 1/4” under rod diameter for easy installation.

Precision Bearing Shells:  Every Ariel compressor features precision-machined tri-metal main and connecting rod bearings.

Versatile Unloading Devices:  Ariel offers manual, head-end variable volume clearance pockets on most cylinders. Pneumatic suction valve un-loaders are available on a limited basis.

Efficient Valving:  Plate-type valves are designed for modern speeds, utilizing non-metallic sealing elements as standard. Valves are selected to comply with established low-valve velocity standards.

Heavy-Duty Crankshafts:  The JG/JGA compressors feature forged steel, precision-machined crankshafts with integral counter-weights manufactured by Ariel Corporation.

High-Efficiency Spin-On Oil Filters:  Ariel JG/JGA compressors feature high-efficiency non-bypassing spin-on oil filters rated at 5 micron nominal and 17 micron absolute.

Rugged Crankcases:  Ariel crankcases are designed for long service life and ease of access during maintenance. Our crankcases feature a heavily-ribbed, high-strength cast iron base with a removable lightweight aluminum top cover.

With cast iron frame, flexible mounting, solid feet, and lower noise levels and operating temperatures, the W22 motors are perfectly suitable for a great variety of industrial applications.
Complies with NEMA Premium efficiency level and carry CSA Certified for Division 2 on the Nameplate as standard.
