Debating between a Screw compressor and a Piston compressor?
Understand the difference between piston vs screw compressor. Learn the benefits of each type of compressor to make the right decision for your needs. Here are some features to consider:
Some Things to know about screw compressors
Screw Compressors are softer on power start-up than piston compressors
20% – 30% more efficient than a piston compressor of the same size
Much quieter, a screw compressor is around 60db compared to a piston compressor of 75 – 80db, meaning no acoustics are required
100% Duty cycle for a screw compressor compared to a piston compressor with just 60% duty cycle.
Discharge temperature of a screw compressor is up to 20C less than a piston in the same environment, causing less strain on the dryer.
No vibration from a screw compressor compared to a piston.
Safety. A screw compressor has over temperature, phase rotation, and current draw cut-out safety whereas a piston compressor does not have any safety cutouts.
With all that being said, you can understand why more often than not, a screw compressor is a better choice for pneumatic systems. What always entices the piston buyer is the low cost. However, it should be noted that the lower-cost option is ideal only for specific environments.
PISTONS
These are typical to low-duty cycle applications or very harsh environments. They are generally more cost-effective at the time of initial buying.
Use a Piston compressor for:
Remote location workshops
Small, low-volume tyre shop or mechanical workshop
Farm machinery shed / workshop
Small service station
Cement batching plants – dusty workspaces
