"Hengtai" tri-lobed Roots blower has been infused with the brand concept since its inception. In 2007, when the actual number of domestic and international Roots blower users reached over a thousand, the company adhered to the Hengtai Roots blower brand philosophy of "Quality as Eternal as the Sun and Moon, Integrity as Weighty as Mount Tai". The construction of the tri-lobed Roots blower brand and after-sales service were closely aligned with the market, and a sales company for Zhangqiu Hengtai tri-lobed Roots blower and an environmental protection equipment factory were established in Pudong, Shanghai. The office of the sales company was located in Chengzhong Garden, Kangqiao Town, Nanhui District.
Currently, the Roots blower industry market is a red ocean. Even in Zhangqiu City, Shandong Province, which is a cluster area for Roots blower industries, there is a mix of good and bad companies. More than thirty small and large Roots blower manufacturers are scattered in the suburbs of Zhangqiu City. A large portion of these companies rely on purchasing parts to assemble their products, while quite a few find assembling Roots blowers troublesome and have resorted to operating shell companies, claiming to be Roots blower manufacturers despite not producing anything themselves.
