Since its inception, "Hengtai" three-lobed Roots blower has been infused with the brand philosophy. By 2007, when actual domestic and international users of Roots blowers reached over a thousand, the company upheld the Hengtai Roots Blower brand philosophy of "Quality as Eternal as the Sun and Moon, Integrity as Heavy as Mount Tai." They closely tied the brand construction of the three-lobed Roots blower to market needs and established the Zhangqiu Hengtai Roots Blower Sales Company and Environmental Protection Equipment Factory in Pudong, Shanghai. The sales company's office was located in Chengzhong Garden, Kangqiao Town, Nanhui District.
Currently, the Roots blower industry market is fiercely competitive, and even in Zouqi City, Shandong Province — a cluster area for Roots blower industries — the market is mixed with good and bad players. Over thirty large and small Roots blower manufacturers are scattered across the suburbs of Zouqi City. A significant portion of these companies rely on sourcing parts for assembly, while others find even assembling Roots blowers troublesome and opt to operate as shell companies, falsely claiming to be Roots blower manufacturers.
In response to such a complex market environment, Mr. Zhang Youwei, Vice General Manager of the company and General Manager of the Shanghai Sales Company (one of the top 100 SMEs in China's e-commerce application in 2007 and one of the top 12 leaders in China's SME e-commerce in 2007), along with two other members, returned to the factory. They analyzed strategies regarding the business opportunities from the 2008 Olympics and the financial crisis and formulated the basic guidelines for "non-standard after-sales service" brand construction. Their aim is to ensure that all sewage treatment projects and pneumatic conveying process lines using Roots blowers, regardless of which domestic manufacturer produced them, can receive after-sales service, maintenance, and updates from Zhangqiu Hengtai Machinery Manufacturing Co., Ltd. This will address the concerns of Roots blower users to the greatest extent possible, especially providing free repair services under abnormal or emergency conditions for environmental engineering companies nationwide.
During the production quality control process, from casting entering the factory to accessory procurement, each production and mechanical processing step is carefully inspected until assembly and debugging. Additionally, there must be a two-day trial operation for every Roots blower before it leaves the factory, with on-site record checks and confirmations. Inspection records show that Hengtai Roots blowers follow procedures according to the ISO9001 quality management system. In some procurement stages, Mr. Zhang checked the original contracts of the procurement department, particularly confirming the procurement of American GATES belts and Japanese NSK bearings, distinguishing themselves from the widespread falsification in the Roots blower industry. Belts and bearings on Roots blowers are critical components directly related to the normal functioning of the heart of sewage treatment projects.
