Designed for continuous duty in the gas and oil industry, these medium-speed separable reciprocating compressors feature a wide range of cylinders, making them the industry choice for standard and specialized applications.

FEATURES

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 JGE/JGK/JGT compressors feature durable connecting rods manufactured from forged steel with 4 bolts and a heavy-duty “I” section.
Rugged Cross heads: One-piece, long-life cross heads with hardened, ground steel
cross head 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: JGE/JGK/JGT 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 nonmetallic sealing elements as standard. Valves are selected to comply with established low valve velocity standards.
Heavy-Duty Crankshafts: JGE/JGK/JGT compressors feature forged steel, precision machined crankshafts with integral counter-weights manufactured by Ariel Corporation.
High-Efficiency Spin-on Oil Filters: Ariel JGE/JGK/JGT 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.
