Leroi 880A Two-Stage Bare Pump Key Features & Benefits

✅ Totally Enclosed Cast Iron Crankcase – Prevents contaminants from entering, reducing maintenance costs.
✅ Precision Finished Disc Valves – Individually removable for easy servicing without removing the cylinder head.
✅ Deep-Finned, Air-Cooled Cylinders – Ensures even cooling and reduced wear, extending piston life.
✅ Rifle-Drilled Crankshaft – Provides direct lubrication to crankshaft and rod bearings for smooth operation.
✅ Matched & Balanced Pistons – Automotive-style pistons are matched for stable, low-vibration performance.
✅ Low Oil Pressure/Low Oil Level Unloader – Protects the compressor by automatically unloading when oil pressure or level drops.
✅ Positive Starting Unloader – Keeps the compressor unloaded during startup, preventing strain on the motor.
✅ Pressure Lubrication System – Rotary vane oil pump delivers continuous lubrication to critical components, preventing dry starts.
✅ Intercooler & Safety Valve (Two-Stage Models) – Reduces air temperature between compression stages for efficient operation and protection against over-pressurization.
✅ Removable Valve Housings & Cylinders – Allows for faster maintenance and reduced downtime.

Pressure Lubrication System
Proper lubrication is a critical factor in the reliability and longevity of a compressor. Simply stated, lubrication begins with the movement of the crankshaft so there’s no chance of dry starting. A positive displacement, rotary vane oil pump is direct driven by the crankshaft. It’s located in the rear retainer assembly, on the opposite side of the crankshaft from the flywheel and is easily accessible. The pump provides pressure lubrication to the crankshaft and connecting rod bearings. Through oil throwoff from the crankshaft, lubrication is provided to the piston pin bushings and cylinder walls. This system helps keep maintenance costs low because the unit is always well lubricated. Service costs are low due to easy pump accessibility, and the easy access facilitates change-over if compressor drive rotation is reversed.
