Avelair's new Variable Speed Air Compressor uses the latest airend, motor and inverter technology to ensure advanced energy savings. They provide an effective energy saving solution for users who have a flexible air demand. Conventional fixed speed air compressors run off load when there is no air demand and this typically uses about 40% of the motor power in lost energy. The Avelair VSD compressor is run by a matched inverter and motor that have been specifically designed for high performing compressor applications. The inverter monitors the compressed air system pressure and allows the compressor motor to speed up and slow down in response to compressed air demand. The result is less energy used which helps the environment and lower electrical running costs which increases bottom line profit.
