Choosing an oil-free screw compressor starts with the air purity your process demands, then balances capacity, duty and cost.
Air Quality Requirement
Confirm the ISO class for your application. Truly oil-free Class 0 machines suit food, pharma and electronics contact air.
Capacity and Pressure
Size free air delivery to peak demand plus reserve, at the required working pressure.
Duty Cycle and Reliability
Match the machine to your run hours and confirm service access and spare parts availability.
Total Cost
Oil-free machines cost more up front but avoid oil contamination risk; include energy and maintenance in the comparison.
