Overview of Kobelco Inverter KOBELION IV VS series 15–75kW air compressors

The single-stage KOBELION IV VS was developed to meet the practical needs of compressed air systems with variable loads, where air consumption is not constant over time. Using fixed-speed air compressors under these conditions often results in significant energy waste due to continuous load-unload cycles.

With advanced inverter technology, Kobelco Inverter air compressor KOBELION IV VS allows the motor speed to be adjusted according to actual compressed air needs, thereby maintaining stable pressure and reducing energy loss.

What is a Kobelco Inverter air compressor? Why is the KOBELION IV VS highly rated?

The concept of inverter air compressors

Inverter air compressors are a type of machine that uses inverter adjusts the motor's rotational speed according to the airflow consumption. Instead of running at maximum power and then releasing the load, the machine will operate flexibly according to the actual needs of the system.

Key features of KOBELION IV VS

Kobelco Inverter air compressor KOBELION IV VS Highly regarded for:

• Precision inverter technology
• Real-time compressed air flow control
• Significant energy savings
• Operates smoothly and stably.

The outstanding advantage of Kobelco Inverter air compressor KOBELION IV VS

Outstanding energy savings

Compared to fixed-speed compressors, inverter compressors significantly reduce energy consumption, especially in systems with variable loads.

Stable operation – precise pressure

Variable frequency drives (VFDs) allow for smooth flow rate adjustment, limit pressure fluctuations, and protect equipment using compressed air.

High durability – minimal wear and tear.

The machine reduces the number of switching cycles and idle periods, thereby extending component lifespan.

Reduce long-term operating costs.

Thanks to energy savings and reduced maintenance, the total cost of ownership of the machine is significantly lower throughout its lifespan.
