Comparison of permanent magnet frequency conversion air compressor with ordinary air compressor:
1. High efficiency and energy saving
Compared with industrial frequency screw air compressors, it can save energy by more than 39.7%; compared with ordinary variable frequency air compressors, it can save energy by 10%.
2. Durable and maintenance-free
The screw host and the motor of the permanent magnet frequency conversion air compressor share the same main shaft, no belts or couplings are required, and the transmission efficiency is high. The motor has no bearings, eliminating the point of failure of the motor bearings.
3. Provide gas volume according to needs, no no-load energy consumption loss
Compared with the traditional control compressor, the inverter-controlled compressor has the most practical significance in energy saving, and the electricity bill completely matches the actual gas consumption to achieve the greatest energy saving.
All LTC Compressor 's products are equipped with Intelligent controller: All the operations and relevant data of the air compressor are displayed on the control panel, which can be controlled at your fingertips, easy, convenient and accurate.
Why choose variable speed screw type air compressor?
It reduces compressor noise—according to the working conditions of screw air compressors, after the compressor is retrofitted with frequency conversion and energy saving, the running speed of the motor is obviously slowed down, and the noise of the compressor is effectively reduced.
Besides, The biggest feature of the permanent magnet variable frequency air compressor is energy saving. Generally, the energy-saving effect reaches 8% and above. It mainly depends on the working conditions and the parameters of the inverter. When the gas pressure of the customer is unstable and fluctuates greatly, the energy-saving effect will be better.
