**Breaker** 32A 3-phase MCCB 63A single
**Cable** 6mm² 4-core 16mm² 3-core
**Generator** Need 20KVA min Need 25KVA min
**AVR** 20KVA AVR ₦450k if NEPA low 25KVA AVR ₦550k

### *Oil & Service Cost Piston 10HP 500L*
Item Price When
**Compressor Oil 4L ISO

### *Test Before Buying Used*
1. *Run to 10 bar*: Must reach 10 bar in 6-7 mins. If 12 mins, pump worn – Rings dead ₦80k fix
2. *Check oil*: Sight glass – If milky white, water in oil, pump bad
3. *Listen*: Knock knock = connecting rod worn. Hiss = valve leak
4. *Tank rust*: Open drain, if brown water + flakes, tank rusted – Don’t buy, tank can burst
5. *Motor*: Run 15 mins, motor must not be too hot to touch >70°C. Check 3-phase amps equal – If 1 phase 20A, other 10A, motor winding bad

### *Key Tips*
1. *Drain daily*: 500L tank makes 1L water per day Lagos humidity. Open drain valve end of day – Water rusts tank
2. *Oil level*: Check weekly – Must be middle sight glass. Low oil = pump seizes ₦250k
3. *Air filter*: Clean weekly – Lagos dust kills pump
4. *Belt*: Must have 10mm play. Too tight = bearing dies
5. *Don’t use engine oil*: Use compressor oil ISO 100 piston / ISO 46 screw only
6. *Install dryer*: If you spray, add refrigerated dryer 10HP ₦450k – Removes water, paint won’t bubble

*Bottom line*:
For tyre shop 2-3 bays / spray booth 4-6hrs/day → *China BORG/CLIDA 10HP 500L Piston Belt 380V 3-phase New ₦1.05M* + *Oil + Filter + Breaker = ₦1.1M ready* – Runs 2 spray guns, 5yr pump life
For factory 8-24hrs/day → *China Screw 10HP 500L Tank ₦2.1M* – Runs non-stop, quiet, no overheating

What are you using it for? Tyre shop, spray booth, factory, or sandblasting? And do you have 380V 3-phase or only 220V? And how many hours per day? I’ll tell you if 10HP 500L piston is enough or you need screw so it doesn’t overheat.
