In de category How do I select the right machine ?Buying a compressor that is too small will waste valuable time and money. Buying a compressor that is too large will waste valuable fuel and money.
(If you are not using the air compressor outside you might consider a stationary air compressor, please refer to the section: How to select my stationary air compressor)
There are 2 parameters that determine the size of an air compressor
1) Required operating pressure (Bar or PSI)
2) Maximum required air usage (Capacity in cfm,, m³/min, ltr/sec)
Please find below a list of some air tools and there average air usag at 6,5 Bar (90 PSI)
Angle Disc Grinder – 180mm / 7” 180- 280 ltr/min (5-8 cfm)
Chipping hammer 2 kg 350 ltr/min (12 cfm)
Chipping hammer 5 kg 430 ltr/min (15 cfm)
Pickhammer 9 kg 900 ltr/min (32 cfm)
Paving / concrete breaker 15 kg 750 ltr/min (27 cfm)
Paving / concrete breaker 20/25 kg 1300 ltr/min (46 cfm)
Paving / concrete breaker 30 kg 1700 ltr/min (60 cfm)
Paving / concrete breaker 40 kg 1850 ltr/min (65 cfm)
Grease Gun 115 ltr/min (4 cfm)
Impact Wrench - 3/8” 70-100 ltr/min (2.5-3.5 cfm)
Impact Wrench - ½” 115-140 ltr/min (4-5 cfm)
Impact Wrench - 1” 285 ltr/min (10 cfm)
Needle Scalar 220-455 ltr/min (8-16 cfm)

For sanblasting nozzle capacities , please 10-15% for nozzle cavitation and wear.
Do I need an air receiver tank with my air compressor?
The size of the compressor tank, usually measured in liter or m³, should be determined by the overall type of usage.
In most cases portable air compressors are modulation controlled and have significant hose lengths and there for receiver are not commonly used.
