Trundean Machinery, with many manufacture experience and professional technology, continuously focuses on Roots Blower and Pumps research and provides reliable & quality products for customers. Not only qualified for ISO 9001 2000 International Quality Certification and CE Certification, but also obtained many awards such as roots blower Structure Improvement, Water Jacket Type Roots Blower improvement, Pump Type Structure Improvement, Roots Blower Structure Improvement…etc.

Unique designed THL Type blower with quality components so that there is no need to lubrication, only the synchronous gear drive system and the shaft bearings are the parts that require lubrication. Separate lateral chambers are designed to house these moving parts with proper seals to prevent oil leakage to the main chamber. In order to lower man-made errors, higher the precision of the leave wheel, and to increase the blower efficiently, our rotor adopts the most advanced one time work process Four-Shaft method. Besides, computerized CNC machines are used to produce components and parts of high quality and precision, also saves the user both time and labor during maintenance and replacement.

The air compartment and the side cover of our blower has a flange and groove rim, which can not only strengthen the blower's operational functions but also prevent eccentric phenomenal resulting from the fastening of the stud, which may reduce the life of the blower. Furthermore, Noise and vibration reduction are the main emphasis in developing the new series of roots blower. The TRUNDEAN Blower rotor concept was adopted based on its flow characteristic which is very stable and even compared to the 2 lobes type, also coupled with the fact that it shows a considerable reduction of both noise and vibration. The extent of reduction can even allow the smaller unit to operate without the need of a silencer.

We, Trundean Machinery, are committed to maintaining product quality and innovation, production standardization, and strict inspection system, in order to ensure that Trundean Roots Blower, Pumps and Diffusers can meet customer's requirement. We offer the best quality products and quick after-sale service. We are capable to make products according to customer’s special request. Custom-made order is welcome.




  • 2-section series
  • Applications of the Pressure Conveyance
  • The maximum pressure:2 kgf/cm²
  • Applications of Vacuum
  • 650 mmHg in a vacuum




  • Lower noise:Pressure pluses are the major noise source in blowers. The Trundean roots blower design can efficiently reduce noise by approximately 5 dB.
  • Lower energy consumption:Trundean roots blower are designed to control backflow pressure to the rotor in order to reduce energy consumption.
  • Longer bearing life:Less vibration transmitted through the lobe results approximately 20% longer bearing life.
