Piston Compressor Spare Parts
What the section includes: all subcategories
Pump Heads (Compressor Blocks)
The pump head is the core working unit. We offer:
- Aircast series heads (REMEZA) — European manufacture for Remeza СБ4/C LB and LT series.
- Direct-drive heads — for compressors without belt transmission.
- Chinese cast-iron heads — universal alternatives for MZB and other Chinese brands.
- Italian-type heads — compatible with Italian compressors (Fini, Abac, Fiac and equivalents).
- Oil-free piston heads — for oil-free compressors used in medical and food applications.
Compressor Oil for Piston Compressors
- Mineral oil — standard SAE 40, change interval 200–300 hours. Eni oil in stock.
- Synthetic oil — extended change interval, better thermal stability for intensive operation.
Cylinder-Piston Group (CPG) Parts
- Piston rings — the most common cause of delivery loss and oil carryover.
- Cylinder liners — for bore wear that rings can no longer compensate.
- Pistons — at cracks or significant skirt wear.
- Connecting rods — at deformation or big-end bearing failure.
- Piston pins — at play in the piston-rod coupling.
Electrical Components
- Condor pressure switch (Germany) — industry standard. Controls motor on/off by receiver pressure. Fault symptoms: compressor doesn't start or stop, unstable pressure.
- Sensors — pressure and temperature sensors for automated compressors.
- Controllers — control boards for electronically managed compressors.
Piston Compressor Maintenance Schedule
| Interval | What is serviced | What is needed |
|---|---|---|
| Daily | Drain receiver condensate | — |
| 50 hours (run-in) | First oil change | Compressor oil SAE 40 |
| 50–100 hours | Clean / replace air filter | Filter element |
| 200–300 hours | Oil change | Compressor oil |
| 500–1,000 hours | Inspect piston rings, valves | Piston rings, valve reeds |
| At symptoms | Replace pressure switch | Condor pressure switch |
| Major overhaul | Replace CPG or complete head | Pistons, rings, liners or assembled block |
How to Select the Right Spare Part
For accurate part selection we need the make and model of your compressor (on the nameplate). If the nameplate is missing — selection can be made from the part's dimensional specs or original part number.
Our specialists help find compatible parts for: Remeza AirCast, MZB, Fini, Abac, Fiac, Boge, Kaeser and other piston compressors
Frequently Asked Questions about Piston Compressor Spare Parts
How often should oil be changed?
Standard interval — 200–300 hours. First change in a new compressor — after 50 run-in hours. Dusty or hot conditions — every 150 hours. Use compressor oil SAE 40.
Symptoms of worn piston rings?
Increased oil consumption, reduced delivery, bluish smoke, cylinder knocking. Inspect and replace piston rings.
What does a Condor pressure switch do?
Condor (Germany) automatically starts and stops the motor by receiver pressure. Fault symptoms: compressor won't start or stop, unstable pressure.
Aircast vs Chinese cast-iron heads?
Aircast (REMEZA, Belarus) — European manufacture, high quality, long service life. Chinese cast iron — more affordable, good life under regular maintenance.
Can synthetic oil replace mineral?
Yes, if the manufacturer permits. Never mix oil types. When switching, completely drain and flush the system first.
