AIR SOURCE TREATMENT

*Air Source Treatment* = Full cleaning of compressed air from compressor to tools. Compulsory in Nigeria if you want clean paint, long tool life, no CNC jam.

Raw air from compressor = water + oil + dust + rust. Must clean.

↓
1. Air Tank 500L/1000L (cools air, water drops)
↓
2. Water Separator / Auto Drain
↓
3. Refrigerated Dryer (removes 90% water) ← You already asked this
↓
4. Main Line Filter (3-stage) ← Removes oil + fine dust
↓
5. Carbon Filter / Adsorption (for food/spray)
↓
6. Air Regulator + Lubricator (for tools)
↓
Clean Air to Factory Loop

### *Pipe Size – Don’t Lose Pressure*
CFM Main Loop Pipe Branch to Machine Material
**40 CFM 10HP** 1 inch 1/2 inch Galvanized or PPR AluPipe
**100 CFM 20HP** 1.5 inch 3/4 inch Galvanized or AluPipe
**200 CFM 40HP** 2 inch 1 inch Galvanized
*Don’t use PVC hose for main line – Bursts at 8 bar.*

### *Key Tips*
1. *Pressure drop*: Each filter = 0.2 bar drop. 3 filters = 0.6 bar. Set compressor 0.6 bar higher than tools need
2. *Bypass*: Install bypass valves around dryer + filters – So you can service without stopping factory
3. *Lowest point drain*: Put auto drain at lowest point of loop – Water collects there
4. *Lagos humidity*: 85% humidity. Without dryer + 3-stage filter, you will have water in 10 mins of running
5. *Don’t mix new + old element*: Always change Q+P+S together if dirty

*Bottom line*:
For 10-20HP factory in Lagos → *STANDARD Treatment = 1000L Tank + 40-100CFM Refrigerated Dryer + 3-Stage Q+P+S Filter Set = ₦1.2M-₦2M* = Clean, dry air for spray, CNC, tools, no water.
