KINGBULL JNV-50A VFD air compressor

Product Description

JNV-50A VFD Screw Air Compressor has always been the hot selling product of KINGBULL air compressor factory. JNV-50A belongs to variable frequency drive air compressor.  Variable frequency drive air compressor automatically adjusts the speed of the air compressor according to the amount of air used by the user and maintains a stable system pressure.

When the air consumption of the system is reduced, the compressed air volume provided by the VFD air compressor will be larger than the system consumption. At this time, the variable frequency compressor will reduce the rotating speed and reduce the exhaust volume of the compressor to maintain a stable system pressure value. If the air consumption of the system increases, the compressed air volume provided by the VFD air compressor will be smaller than the system consumption. And the frequency conversion compressor will increase the rotating speed, increase the exhaust volume of the compressor. So as to maintain the stability of the system pressure value.

50 hp variable speed drive air compressor

This mode of operation allows the variable frequency drive air compressor to directly respond to changes in system pressure. So as to provide the amount of gas 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. The output air volume of ordinary air compressor is constant. The actual consumption of compressed air is generally fluctuating. Email:info@fntcompressor.com

Customers generally choose the air compressor model to meet the maximum actual air consumption. When the output air volume is greater than the actual consumption, the air compressor adopts no-load mode to adjust the system pressure. And a certain amount of energy consumption will be lost when the air compressor is no-load. The advantages of VFD screw air compressor can not only save electricity, but also provide stable exhaust pressure, improve motor power factor. At the same time, VFD screw air compressor can reduce start-up power supply effectively and prolong the service life of compressor. Email:info@fntcompressor.com
