    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 strength.

    KBK Conrod

    Rigid Connecting Rods

    The KBE compressors feature durable connecting rods manufactured from forged steel with a 4-bolt 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 horizontal and double-acting cylinders eliminate the cost of a cylinder cooling system and remove the maintenance problems associated with water cooling.


      Durable Pistons and Rods

      The KBE compressor features 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 compact 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 KBE compressor features forged steel, precision-machined crankshafts with integral counter-weights manufactured by Ariel Corporation.

      Spin On Filter

      High-Efficiency Spin-On Oil Filters

      The Ariel KBE compressor features high-efficiency spin-on oil filters rated at 5 micron nominal and 17 micron absolute.



      Rugged Crankcase

      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 removable a lightweight aluminum top cover.
