Lubrication

Lubrication

 N/A
  • Superior lubrication is accomplished through a gear driven oil pump powered by the crankshaft.
  • Pressurized system ensures complete lubrication to the crankshaft, connecting rods, bearings and piston pins.
  • Full flow, spin-on oil filter ensures impurities are removed before the lubricant contacts any internal components.
  • Oil pressure gauge is conveniently mounted to display the oil pressure.

Valves

Valves

 N/A
  • Concentric ring design incorporates both the inlet and outlet valves in one assembly.
  • Designed to give 100% exposure to the air flow for maximum efficiency (i.e. more CFM per HP).
  • Discs and springs are made of AISI 420 stainless steel to give dependable corrosion-free and fatigue-free service life.

Standard Features

Standard Features

 N/A
  1. ASME pressure relief valve protects the intercooler and first stage from over pressure.
  2. Suction unloading valves (where applicable) provide load less starting and stopping as well as quick response to capacity demands.
  3. Removable hand-hole plate allows easy access to the internal running gear.
  4. Tri-Metal insert bearings are two-piece for quick and easy replacement.
  5. Counterbalanced crankshaft assures smooth operation.
  6. Replaceable piston pin bearings are very economical when replacement becomes necessary.
  7. Deep-finned cylinders and heads quickly dissipate the heat of compression.
  8. Crankshaft ends are supported by large tapered roller bearings for smooth operation and long life.
  9. Oil pressure gauge assures the operator of lubrication system integrity.
  10. The cylinders and crankcase are built of industrial strength cast iron materials.
  11. Continuous Operation
