Screw vs. Piston Compressors: How to Choose
A three-dimension comparison: capacity, noise and maintenance cost.
Capacity: screw compressors suit continuous demand above 5 m³/min while piston units suit small intermittent demand. Noise: screw units can be installed near points of use; piston units usually need a separate room. Maintenance: screw units cost more upfront but have longer service intervals and lower total cost.
For 24/7 factories, screw compressors are almost always the rational choice.
