7 Checks Before Choosing a Air Compressors Supplier
1. Type
Choose rotary screw for continuous duty, piston for intermittent use.
2. Flow
Match free air delivery (m³/min or CFM) to total tool demand.

Confirm working pressure (usually 7-10 bar) for your tools.
4. Oil-free
Select oil-free units for food, pharma, and clean-room air.
5. VSD
Variable speed drives cut energy on fluctuating demand.
6. Air treatment
Add dryers and filters for quality air where needed.
7. Certification
Verify CE and electrical specs for your destination market.
Frequently Asked Questions
What is the difference between screw and piston compressors?
Rotary screw units run continuously for industrial use, while piston units suit intermittent shop use.
What CFM compressor do I need?
Add the CFM of all tools used at once and add a 25-30% margin for demand.
Do I need an oil-free air compressor?
Yes for food, pharmaceutical, and electronics applications requiring clean air.
What is the MOQ for air compressors?
Machines are typically sold per unit, with volume pricing on multiple units.
