AIR COMPRESSOR 50 LTR CAZAR (CZ-OC-2)
While the model number CZ-OC-2 is traditionally associated with Cazar's Oil-Free/Silent series, Cazar also produces Oil-Based (Lubricated) compressors in the 50-liter category.
If you are looking for the Oil-Based version, it is a "Direct Drive" piston compressor. This type is more rugged for heavy-duty workshop tasks compared to the silent oil-free models.
CAZAR 50 LTR Oil-Based (Lubricated) Compressor
Below are the typical specifications for the Cazar 50L oil-lubricated model (often identified as the standard Cazar 50L Direct Drive):
| Feature | Specification |
| Tank Capacity | 50 Liters |
| Motor Power | 2.5 HP to 3.0 HP (High Torque) |
| Type | Oil-Lubricated (Piston / Direct Drive) |
| Air Displacement | ~200 – 250 Liters Per Minute (LPM) |
| Max Pressure | 8 Bar (116 PSI) |
| Noise Level | ~85 – 95 dB (Loud, typical workshop sound) |
| Lubrication | Oil-splashed (requires regular oil checks/changes) |
| Winding | 100% Copper Winding |
| Couplers | Dual quick-release couplers (usually) |
Key Differences: Oil-Based vs. CZ-OC-2 (Oil-Free)
Power & Speed: Oil-based compressors usually have a higher HP motor (2.5HP+) and a single large piston. They build pressure faster than silent models.
Maintenance: You must monitor the oil sight glass and change the compressor oil (usually SAE 30) periodically. The CZ-OC-2 requires zero oil.
Duty Cycle: Oil-based units handle heat slightly better for continuous, heavy pneumatic work (like using impact wrenches or continuous sanding), though they are much louder.
Air Quality: The air from this unit contains trace amounts of oil vapor. It is not recommended for dental use or high-end medical applications unless you use a high-quality oil/water separator filter.
Maintenance Essentials for Oil-Based Models
Oil Check: Always ensure the oil level is at the red dot in the sight glass before starting.
Drain the Tank: Daily drainage of the bottom valve is required to prevent water/rust buildup.
Air Filter: Clean the intake sponge filter every 20 hours of use to maintain airflow.
