Yuzhen Engineers Install 75kW Hanbell Two‑Stage VFD Air Compressor for Automotive Parts Factory in Vietnam

Recently, in the production workshop of an automotive parts factory in Vietnam, two new pieces of equipment were waiting to be put into service. The system is a 75kW Hanbell two‑stage variable frequency drive screw air compressor, which will supply compressed air for multiple production lines including stamping, welding, and pneumatic assembly.

At eight in the morning, two Yuzhen after‑sales engineers arrived on site. Without any small talk, they got straight to work – unpacking the equipment, checking the inventory, and inspecting the foundation load. The old compressor had just been removed, requiring a complete re‑layout of the piping. Engineer Wang took charge of positioning the main unit, while Engineer Yan focused on designing the piping route.

"Automotive parts plants have very high requirements for oil content and water content in compressed air – the post‑treatment must be adequate," said Wang while installing the air receiver tank. The two worked in perfect coordination: one welded the stainless steel piping, the other installed the refrigerated air dryer and three stages of precision filters. Every connection was leak‑tested repeatedly to ensure no air leakage.

During the power‑on commissioning phase, they carefully checked the voltage, phase sequence, and set the VFD parameters. As the start button was pressed, the unit loaded smoothly, and the control panel showed a stable discharge pressure of 0.8 MPa. "Vibration is normal, noise is much lower than expected," Yan recorded in his notes.

After two hours of continuous trial operation, the customer's production manager arrived. After checking the flow and pressure curves, he said with satisfaction, "I didn't expect the installation to be so fast and the operation so stable. You even arranged the piping neatly – it looks great!"

Before handing over, the two engineers gave half an hour of training to the plant's operators, explaining daily inspection points and fault code meanings. Before leaving, they attached a inspection reminder sticker to the unit.

From arrival to delivery, it took only two days. The Hanbell 75kW two‑stage VFD air compressor officially became the "power heart" of the automotive parts factory, and the Yuzhen engineers, with their professionalism and attention to detail, earned valuable time for the customer.
