### *Key Tips Before Buying*
1. *Check ACTUAL CFM at 8 bar*: Some China brands lie. Ask for test
2. *Hours meter*: Good screw has hour meter. <15000hrs = good used
3. *Airend*: The screw block. If it whines = ₦800k to replace. Avoid
4. *VSD needs clean power*: Dust kills VSD board ₦300k. Keep in clean room
5. *Service history*: For used Atlas/Kaeser, ask for service book

*Warning*: Real 10HP screw needs 415V 3-phase 20A minimum. Cannot run on 220V or small generator. Need 30KVA gen minimum.

*Bottom line*:
For factory 8hrs/day → *VSD 10HP Screw + 500L + Dryer* ₦3.2M China / ₦6M German
For occasional use → Piston double tank 10HP ₦1.6M is cheaper upfront
