Rotary screw air compressors are an increasingly popular alternative to the more traditional reciprocating air compressors, and it’s no wonder why. Their advanced technology allows for greater air pressure and longer durability, but how does one actually work? At Mobile Energy Australia, we are here to answer all of your rotary screw air compressor questions including some suggestions about which of our products use this exciting technology.
How a Rotary Screw Air Compressor Works
Air compressors are pieces of equipment that use pressurised air to power pneumatic tools. The difference between rotary screw and reciprocating air compressors is how their interiors have been designed to make this pressurised air.
Traditional reciprocating air compressors have been around for decades and use pistons to push air into a small space, and then collects this air into an air receiver tank. This process is similar to how your car engine works.
Rotary screw air compressors are a newer piece of technology and involve two mesh rotors trapping air and moving that air down into a more compact space. This compresses the air which is then channelled through to the tank.
The rotary screw air compressors sold by Mobile Energy Australia are all oil-injected, meaning that oil is used to lubricate the rotors before being recycled back through the air-end. This allows the compressor to offer high PSI and cfm at a continuous duty cycle.
The Benefits of Rotary Screw Air Compressors
Rotary screw air compressors offer plenty of advantages over their piston-powered counterparts. Listed below are just some of the few reasons why rotary screw air compressors are a beneficial alternative:
- 100% Duty Cycle – rotary screw air compressors are able to provide continuous air flow for the entirety of their cycle time. This means you will never have to cool down the unit between uses.
- Provides more air – the design of rotary screw air compressors creates and stores larger quantities of pressurised air than other makes.
- Provides more CFM – the higher speed at which rotary screw air compressors operate means that the cubic feet per minute (CFM) of air output is greater overall.
- Quieter – your hearing won’t be at risk every time you use a rotary screw air compressor as they operate more silently than reciprocating models.
In terms of disadvantages, rotary screw air compressors will generally be more expensive than reciprocating air compressors due to the technology being newer and more costly to manufacture. However, prices are coming down and its only a matter of time before both models are given comparable market value.
