Variable Speed Air Compressors

Optimum energy efficiency with premium inverter drives and high efficiency motors.

The Avelair range of evo air compressors use the latest rolling profile airends ensuring optimum efficientcy. They are the product of vigorous testing and re-evaluation, which has resulted in one of the most dependable air compressors on the market today. All our air compressors are extensively tested before leaving the factory ensuring long term reliability and giving you peace of mind.

The Avelair VSD compressor provide an effective energy saving solution, and in qualified applications it saves up to 30% of energy costs. The compressor is run by an inverter that has been specifically designed for high performing compressor applications. This inverter senses the compressed air system pressure and causes the compressor to speed up and slow down in response to demand for compressed air. The result is any energy lost through off load running can be significantly reduced and the inverter ensures that the compressor accurately maintains system pressure.

When is a VSD the right choice?

The Avelair VSD compressor will be practically effective in saving energy where there are significant peaks and troughs in demand for compressed air. It can also be effective when combined with a standard fixed speed compressor to top up a compressed air system during times of variable demand.

Practical technology that works

The compressor incorporates a high quality specially programmed inverter. Linked to the compressor control system, the inverter software has been specifically designed to operate in harmony with the Avelair hardware, providing a robust and practical application of technology that is thoroughly suited to the industrial environments.

Variable speed air compressors facts

The perfect choice for users who have a variable compressed air demand.
The compressors use a high performance inverter to smoothly alter the motor speed in response to demand for air, ensuring there is no offload running. You only pay for the compressed air you use.
In many cases this can reduce energy costs by 35% or more, with paybacks from around 6-18 months.
The inverter further saves energy by accurately maintaining the system pressure within a 0.1 bar margin, and by soft starting which reduces start up current peaks and wear on the motor and drive system.
The Avelair variable speed compressors mirror the demand for air by altering the motor speed ensuring you only pay for the air you use.

Energy technology list

The Avelair’s variable speed air compressors use efficient inverters that are qualified for the Enhanced Capital Allowance (ECA) and can provide businesses with enhanced tax relief for investments in equipment that meets published energy-saving criteria.
