Permanent Magnet Variable Speed Compressor Industrial Rotary Air Compressor
Variable speed drive allows the air compressor to automatically adjust the motor speed to adapt to different working conditions. Since energy costs account for more than 75% of the total cost, using VSD air compressors can not only save a lot of money, but also save more energy for the environment
Benefits of a Variable Speed Compressor
No need to unload - the ability to start and stop under full system pressure.
Reduced power costs - no loss of energy through running unloaded.
Reduced power surges - avoid peak currents from starting air compressor motor.
More energy efficient - save 30% of the energy used by a typical fixed speed compressor.
Precise electrical control - motor speeds can be slowed down, brought to a halt or revved up.
System leaks minimised - lower system pressure reduces the risk of leaks.
