1, Company Brief

①In 1994,Yixing Pengde Machinery Co.,Ltd. ( a Sino-Japanese joint Venture) was born,and relocated in the Industrial Park for Environmental SCI and TECH. The following year with company name changed to B-Tohin Machine (Jiangsu)Co.,Ltd.

②Localization of HC blower in 1996

③In 1999,established a joint venture named Tohin Machine Co.,Ltd. with TUTHILL Pneumatics Group (United States).

④Localization and mass sales of BK blower in 2000

⑤In 2004,HC Blower and BK Blower got the honor of “new high-tech product”,and the company was rated as a high-tech enterprise. In the same year,the company passed ISO9001 certification,purchased more than 30000 square meters for new plant and donated 500000 yuan to build the B-Tohin Qinghu Hope Middle School.

⑥In 2009,the single-stage high-speed blower was successfully launched, and BK was rated as famous trademark of Wuxi City and famous trademark of Jiangsu Province.The torch program project of Jiangsu Province and a number of patents were achieved ,also the company’s together-with-heart idea: attentively,sincerely,confidently was put forward.

⑦The company’s BK brand was rated as “China Well-known Trademark” in 2013.

⑧In 2014,the company was identified as “Jiangsu Aerodynamic Research Center” by the Science &Technology Department of Jiangsu Province,and got the ISO14001 certificate.At the same time,Office Automation was put into use successfully.

⑨In 2015,the company introduced a whole blower performance test system.Successfully bid for the 2600 square meters industrial assets in Yixing economic development zone and established Wuxi B-Tohin Blower Technology Co.,Ltd.

⑩In 2016, Sino-Korean joint venture Wuxi B-Tohin & Ace Blower Science and Technology Co.,Ltd. was established. In the same year,air foil centrifugal blower was successfully introduced,and Tohin Vietnam Industry was founded.

⑪In 2017,the company turned on the Internet of things intelligent ,the balance tester of Air Bearing Turbo Centrifugal blower was successfully put into use .The Science and Technology Association of B-Tohin was founded.

⑫In 2018, B-Tohin magnetic suspension centrifugal blower,stainless steel blower and other new products were successfully launched.

⑬In2019,Adopted the ERP platform management in the whole company and passed the assessment of “Informational and Industrialize Integration” in 2019.

⑭B-Tohin screw blower was put on market successfully in 2021.

⑮Launched contract energy management and new type product lease sales in 2022.With a new area of 75000 square meters acquired, the project of design and intelligent manufacturing base of high efficiency blower and office building of B-Tohin started.

The new factory building was successfully completed and relocated.

2,Main characteristics

(1) Optimized lobe curve is adopted for reducing blower's internal leakage, improving blower's efficiency

and reducing running temperature.

(2) After shaft's diameter enlarged, no deformation and collision will occur under higher load pressure as

the blower's strength is improved.

(3) The synchromesh gear adopts straight tooth structure for smooth operation.

(4) Deep groove ball bearing of high precision and low friction factor is selected for lowering operation

noise. In addition, because of larger size bearing matched for enlarged shaft diameter, the bearing's load

capacity is enhanced and its service life is extended.

(5) Low noise and vibration, compact and economical energy consumption.

3 Blower working principle

Roots blower is a cubage, and it discharges a fixed amount of air in proportion to rotation speed. Two

parallel shafts have three lobes each, all the lobes keep small clearance with each other and housing

inside. Every lobes rotation, a certain  air will be absorbed at inlet and transferred from the housing inside

surface to blower's discharge port.

Two shafts will be turned by timing gears, no any touching between lobes, so it can be turned at high speed

without any lubrication inside, It has the following characteristics: simply configuration; running smoothly;

good performance stabilization. It has been widely applied in various industries.
