Rotary screw and reciprocating air compressors are both widely used, but they serve different jobs. Understanding the differences prevents an expensive mistake.
Continuous vs Intermittent Duty
Rotary screw machines are built for continuous operation and suit factories that run compressed air all day. Reciprocating piston units are better for intermittent use and small workshops.
Flow and Pressure Profile
Screw compressors deliver steady flow at moderate pressure, while piston compressors can reach higher pressure at lower volume. Match the type to the job, not the brand.
Maintenance and Lifetime Cost
Screw compressors generally need scheduled servicing but handle heavy duty well. Piston machines cost less to buy but may require more attention in continuous use.
