Nothing outworks a rotary screw when it comes to air compressors. Rotary screw air compressors are designed for continuous use without overheating, saving you time—no more waiting for your air compressor to catch up. This article will help you pick out the right rotary screw air compressor for your needs.
Do You Require a Rotary Screw Air Compressor?
Rotary screw air compressors are designed to handle large volumes of compressed air requirements. So these machines are great if you need continuous compressed air in a commercial or industrial setting.
However, it’s unlikely that you’ll need a rotary screw compressor if the application is for smaller jobs (e.g., personal projects) or small pneumatic hand tools. In other words, if you require air intermittently, you probably don’t need a rotary screw air compressor.
Consider Feature Options
Rotary screw air compressors can come with various optional features or extras. Knowing what the extras are and what each one does should prevent unnecessary purchases. Here are the typical extras.
Electronic Condensate Trap or Drain
Condensate drains can become a maintenance issue when clogged or dirty. That’s because the compressed air system will take-in lots of water whenever the condensate trap isn’t functioning.
“A mechanical condensate trap has to be manually drained daily or weekly. However, an electronic condensate trap can ensure your air compressor’s tank is drained whenever needed” – Hertz Kompressoren
Integrated Air Filters and Dryers
Some manufacturers offer all-in-one solutions, where there’s an integrated compressed air dryer or filter or both. The air dryer and filter are usually recommended for most rotary screw air compressors. That’s because clean compressed air is better for equipment in terms of life-span.
Belt Drive or Direct Drive
You can typically choose between a belt or direct drive rotary screw air compressor. With a belt drive compressor, the pump is powered as the belt turns while the motor runs. For direct drive air compressors, the crankshaft connects directly to the motor. Belt drive units produce less noise but are typically more compact.
Variable Speed Drive (VSD)
A variable speed drive matches the output capacity to actual demand, therefore, saving you money on energy.
The compressed air that leaves your compressor would be too hot without an aftercooler. So Aftercoolers come standard with most rotary screw air compressors. These mechanisms also remove water from compressed air.
If you’re ready for something tough and reliable, then consider picking up a rotary screw air compressor. Your equipment and tools should work as hard as you do.
