List tools by real operating pattern
Record the rated air consumption of lifts, tyre changers, impact tools, sanders, spray guns, blow guns and any automated equipment. Note which tools can run together and for how long. Spray work and continuous sanding can dominate demand even when impact tools have a higher short peak.
Check pressure at the tool
Most workshop tools have a stated working pressure. Long small-bore hoses and restrictive quick couplers can cause a large drop. A compressor should not be oversized simply to compensate for poor distribution. Improve the main line, drops and hose selection first.
Match technology to daily hours
A small workshop with brief, occasional use may suit a piston compressor. A busy automotive, panel beating or fabrication workshop using air throughout the day will often benefit from a rotary screw compressor. Noise, heat and duty cycle should be considered alongside purchase price.
Treat air for the job
Tyre inflation and general tools may tolerate a simpler treatment package than spray painting. Paint quality is sensitive to water, oil and dirt, so the dryer and filters must be selected carefully. Drain points and pipe layout also influence contamination at the booth.
Allow for business growth without wasting energy
Include credible additions such as another bay, spray booth or CNC machine. Avoid buying a machine several sizes too large for a future plan that may not happen. A modular system, receiver storage or later second compressor may offer better efficiency and redundancy.
How we help workshops choose
Send us the tool list, number of bays, operating hours and electrical supply. We calculate simultaneous demand, check whether piston or screw technology fits, and recommend the receiver, dryer and filtration package. We can also review pipework and point-of-use pressure problems.

Build an initial estimate for compressor demand, receiver size and electricity cost, then send the result to our team for verification.
Frequently asked questions
It depends on the number of simultaneous users, sanding and spray demand, duty cycle and pressure. A tool list gives a better answer than workshop floor area.
It can be a compact solution where space is limited, provided receiver volume, ventilation and treatment are correctly selected.
Dry, clean air is important for finish quality. The exact treatment package should match the paint process and environment.
