Why a Variable Speed Compressor?
How
to know a VSD compressor is the right pick?
Speed control of a compressor is regulated by a variable speed drive, often known as VSD. This option uses the variable-speed drive technology to control the speed of the compressor based on what is being demanded from the compressor.
Is a VSD right for me?
A variable speed compressor is not for every application. VSD rotary screw compressors need to be ran in a location that is in need of 24/7 compressed air and has a changing demand on the amount of air needed. If your compressed air needs are constant, or even mostly constant with only occasional slight variations, a variable speed compressor may not be necessary. With variable speed drive air compressors, the unit makes adjustments to match the demand needed. The motor runs only at the speed you need, giving you the right amount of compressed air at the right pressure, and at the right time.
Advantages of a Variable Speed Compressor
- Reduced energy consumption (in the proper application) - Quieter than a fixed speed when running at a lower RPM - Consistent plant pressure - Increased component lifetime - Less maintenance cost and ease of maintenance - Low inrush current during motor starts - Compact total solutions available - May qualify for energy incentives The inverter in the VSD system performs a โsoftโ start operation by ramping up the motor speed. This removes amperage draw peaks that are normal when a fixed speed motor starts. The soft starting used by a VSD compressor also helps protect electrical and mechanical components from the starting mechanical stresses that can reduce the life of an air compressor.
A huge benefit to a VSD compressor is reducing power cost, minimizing power surges and delivering a more constant pressure needed. When there is minimal demand, the drive runs slower using less electricity. The higher the demand, the VSD runs wide open and can operate anywhere in between depending on the system demand for air.
Flexibility
With our VSD line-up, we have the combination you need to fit your business. Tank, base-mounted, full-featured? We have what you need.
Save Energy & Money
Achieve average energy savings of 35-50% and an average 22-37% reduction in life-cycle cost.
Did you Know?
Power companies usually will impose penalties for amperage peaks in the form of higher rates. These are common with fixed speed compressors.

Oil Free - Screw Air Compressors
The team at AshAir specialises in oil-free or oil-less scroll compressors with zero risk of oil contamination, and are ideal for critical applications including medical, pharmaceutical, dental, R&D, food & beverage, wine and brewery. Our 100% oil-less scroll compressors are designed with fewer moving parts, which means less wear and tear, less noise, higher efficiency and reliability, and a longer machine life .
These scroll compressors use cutting-edge scroll technology where the spirals never contact each other, and no lubrication is needed, making them completely oil-free. Our SPR 20 Multi oil-less scroll compressor operates with variable air delivery, controlled by an intelligent controller for air delivery supplied according to the fluctuation of air demand. This means a higher energy efficiency and more stable system pressure.

Maintenance budget: 8 factors to consider
Just like any other equipment, a compressed air installation also requires the necessary maintenance work during its entire lifespan. Even though maintenance costs are only about 5 to 10% of a machine's annual operating costs, failure to budget for maintenance can have potentially disastrous consequences. Read More…

Why Replace CO2 with Nitrogen in your Brewery
Using nitrogen is not about fully replacing CO2, but it can reduce their consumption of CO2 by close to 70%. Using nitrogen is about sustainability. Creating your own nitrogen is easy and will reduce the use of a greenhouse gas, which is better for the environment. It will also save you money as early as month one adding that savings to your bottom line. Read More…
