Get instant CFM and bar recommendations for your UAE project. Our calculator considers tool demand, hose pressure loss, simultaneity, and high ambient temperature derating across Abu Dhabi, Dubai and all Emirates.
Quick reference for typical air compressor capacities by project type in UAE climate conditions.
5-20 workers; grinders, small breakers, paint; short hose runs. Add 15% for 50°C operation.
20-50 workers; multiple pneumatic tools; extended air lines with distribution manifolds.
Heavy-duty use, continuous operation, parallel compressors, aftercoolers, and dryers.
Use this quick reference to estimate the air consumption and pressure requirements of common tools in UAE construction and industrial sites.
| Tool Type | CFM Range | Pressure (bar) | Duty Cycle | UAE Notes |
|---|---|---|---|---|
| Jackhammer / Breaker | 25 - 35 | 6 - 7 | Intermittent | High dust—inspect filters daily in Abu Dhabi/Dubai sites |
| Paint Spray Gun | 15 - 20 | 3 - 4 | Continuous | Requires oil-free, dry air; add refrigerated dryer |
| Angle Grinder | 5 - 8 | 6 | Intermittent | Multiple units typical; size for simultaneity |
| Sandblasting Nozzle | 50 - 100 | 7 - 8 | Continuous | Moisture control critical; use aftercooler + dryer |
| Impact Wrench | 8 - 12 | 6 | Intermittent | Receiver tank helps manage surge demand |
Answers to the most common sizing questions for air compressors in UAE conditions.
Sum individual tool CFM, apply simultaneity (0.7-0.8), add pressure loss factor for hose length/diameter, include 10-15% climate derating for UAE, then add 20% safety margin. Our calculator automates these steps for Abu Dhabi/Dubai conditions.
Most pneumatic tools run at 6-7 bar. Sandblasting needs 7-8 bar, spray paint uses 3-4 bar but requires dry, oil-free air. Convert bar → PSI by multiplying by 14.5 (7 bar ≈ 101 PSI).
Use larger main hoses (1.5-2 inch) for flows above 75 CFM or runs beyond 50 meters. Keep fittings to a minimum, and place a receiver tank close to the work area to absorb surge demands.
Yes. Temperatures of 45-50°C reduce compressor efficiency. Add 10-15% to your calculated flow and ensure proper shading/ventilation for stable operation in summer months.
