Air Compressor Types - Selection and Usage Guide
Air Compressors
The compressor is essential equipment in workshops, factories, and construction sites. It provides compressed air for pneumatic tools, spray painting, and more.
Types of Compressors
1. Piston/Reciprocating Compressor
- Most common and economical.
- Suitable for small and medium workshops.
- Types: single cylinder, twin cylinder.
- Tank capacities: 24, 50, 100, 200, 500 liters.
- Needs rest periods (not for continuous operation).
2. Rotary Screw Compressor
- For continuous 24/7 operation.
- Quieter than piston type.
- Higher efficiency for industrial use.
- More expensive to buy and maintain.
- For factories and large workshops.
3. Portable Compressor
- Small and lightweight (6-25 liters).
- For tire inflation and light tasks.
- Some are battery-powered (12V).
- Suitable for mobile technicians.
How to Choose Capacity and Power?
| Use | Required CFM | Tank Capacity |
|---|---|---|
| Tire inflation | 2-3 CFM | 24-50 liters |
| Spray gun | 5-8 CFM | 50-100 liters |
| Pneumatic tools (driver/hammer) | 4-6 CFM | 50-100 liters |
| Sandblasting | 10-20 CFM | 200-500 liters |
| Factory (production line) | 20+ CFM | Screw + large tank |
Compressor Maintenance
- Drain condensed water from tank daily.
- Check oil level weekly (for lubricated piston type).
- Clean air filter monthly.
- Inspect belts every 3 months.
- Change oil every 500-1000 operating hours.
