On construction and infrastructure sites, air supply equipment is increasingly expected to deliver not only performance but also environmental features such as drainage treatment and compatibility with lower-impact energy solutions.
At CSPI-EXPO, AIRMAN Corporation introduced the environmentally conscious engine compressor “PDSG750LVRD-4C5.” The model has a rated pressure of 1.4 MPa and an air delivery volume of 21.2 m3/min, and its operating pressure can be switched from the control panel to 1.03 MPa or 0.7 MPa depending on the application.
The machine is designed as a dry-air specification model and can be equipped with an optional system to reduce oil content in drained water. This helps treat condensate water containing compressor oil to a level suitable for discharge outside the machine under applicable legal requirements.
The company changed its name from Hokuetsu Industries Co., Ltd. to AIRMAN Corporation in April 2025, aligning the corporate name with its long-established product brand. It continues to develop engine compressors, generators, aerial work platforms, biofuel-compatible generators, and electrically actuated aerial work equipment.

On April 1, 2025, we changed our company name from Hokuetsu Industries Co., Ltd. to AIRMAN Corporation.
By unifying the company name with the long-established product brand, we aim to improve recognition and further strengthen the brand.
The machine we are introducing is the environmentally conscious engine compressor model PDSG750LVRD-4C5.
Its rated pressure is 1.4 MPa and its air delivery volume is 21.2 m3/min.
By setting it on the control panel, the pressure can be easily switched to a medium pressure of 1.03 MPa or a low pressure of 0.7 MPa.
Although it is a dry-air specification model, the removed drainage water contains compressor oil, so it cannot be discharged as-is. With this new model, an optional system can remove oil from the drain water to a level that does not cause legal issues when discharged outside the machine.
At this exhibition, we are displaying environmentally conscious products like this.
We are also exhibiting biofuel-compatible generators and aerial work platforms equipped with electric cylinders, so please take a look if you are interested.
Thank you.
