What is VFD air compressor?

The variable frequency drive air compressor automatically adjusts the speed of the screw air compressor according to the amount of air used by the user. At the same time, maintains a stable system pressure. When the air consumption of the system is reduced, the amount of compressed air supplied by the compressor will be more than the system consumption. And then, the variable frequency drive compressor will reduce the rotor speed. And VFD compressor will reduce the exhaust volume of the rotary air compressor to maintain a stable system pressure value. Our company supply high quality air compressor for sale. Please feel free to leave your message to get best price on air compressors. Email: info@fntcompressor.com

100 hp variable frequency air comprssor factory

If the air consumption of the system increases, the compressed air volume provided by the industrial air compressor will be less than the system consumption. And the VFD compressor will increase the rotating speed. Meanwhile, VFD air compressor will increase the exhaust volume of the 75 hp air compressor. So that to keep the pressure value of the system stable. This mode of operation allows the VFD variable frequency drive air compressor to respond directly and quickly to the change of system pressure. Thus, VFD for air compressor can provide the exactly air consumed by the system. Through this operation mode, the variable frequency drive air compressor can maintain the best operation efficiency between the output air volume and the system consumption.

Why choose variable frequency drive air compressor?

The output air volume of ordinary air compressor is constant, while the actual air consumption is generally fluctuating. Customers generally have to meet the maximum actual air consumption when selecting the air compressor model. When the output air volume is more than the actual air consumption, the VFD speed air compressor adopts no-load mode to adjust the pressure of the system. Therefore, a certain energy consumption will be lost at no-load. Email: info@fntcompressor.com

In addition to the clear benefits of power saving, the advantages of the VFD air compressor can also provide stable exhaust pressure. At the same time, improve motor power, effectively reduce the start-up power supply. And prolong the service life of screw type air compressor. If you are looking for a professional 100 hp VFD air compressor manufacturer. KingBull air compressor company will be your right choice.

What are the advantages of KingBull VFD compressor?

VFD air compressor Energy saving

Compared with the traditional controlled air compressor, variable frequency drive air compressor VFD energy savings is the most practical. The industrial control of industrial air compressor supplied according to the demand of air volume is the economical operation. 120 hp VFD rotary screw compressor can save about 20% of electricity costs. Therefore, you can recover the invested funds in about half a year. Email: info@fntcompressor.com

Reduced screw air compressor operating costs

The operation cost of traditional compressor consists of three parts: initial purchase air compressor cost, maintenance cost and energy cost. The energy cost accounts for about 77% of the operating cost of the workshop air compressor. The variable frequency drive air compressor has a 44.3% reduction in energy cost. And the impact on the equipment after the VFD start-up is reduced. Therefore, the maintenance cost is also reduced. So that the running cost will be greatly reduced. If you want to buy energy saving air compressor, please send e-mail to us now.

VFD for air compressor improve the accuracy of pressure control

The air compressor variable frequency drive control system has the accurate pressure control ability. So that the air output of the screw air compressor matches the air volume needed by the user air system. The output air volume of the VFD screw compressor changes as the motor speed changes. Due to the improved accuracy of the variable frequency control motor speed. It can keep the pressure change of the pipe network in the range of ±0.2bar. And effectively improve the quality of the working condition. Email: info@fntcompressor.com

Prolong the life of the rotary screw air compressor

The inverter starts the frequency variable compressor from 0Hz. And its starting acceleration time can be adjusted. Thereby reducing the impact on the electrical and mechanical components of the rotary air compressor during starting. Enhancing the reliability of the system and prolonging the service life of the screw air compressor.
Reduce the noise of the VFD air compressor.

reliable KingBull VFD compressor factory price

According to the working condition requirements of the compressor, the running speed of the motor is obviously slowed down after the transformation of frequency conversion speed regulation. So the noise during the operation of the VFD screw air compressor is effectively reduced. Field measurements indicate that the noise is about 3 to 7 decibels lower than the original system. If you want to buy noiseless air compressor, KingBull air compressor manufacturer is certainly your best partner. Email: info@fntcompressor.com
