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.

For traditional water-cooling blowers, the cog wheels can only be partly cooled, which can cause an over-heat then break down the machine. Our new design THW type blower has the special feature that the main air room can be completely covered by the cooling water, this way the machine can stand higher heat, particularly in high pressure conveyance and the puffing air. Our rotor is made by the most advanced one time work process Four-Shaft method in order to reduce man-made errors, enhance the precision of the leave wheel, and to promote the blower efficiently.

And the flange and groove rim of the air compartment and the side cover of our blower can not only reinforce the blower's operational functions but also keep eccentric phenomenal resulting from the fastening of the stud, which may reduce the blower life. Also, low Noise and Minimal Vibration are also the main features of our blowers. In addition, the special design for reducing the body temperature by using water between the body, and the casing and the Separate lateral chambers that designed for housing the moving parts with proper seals to prevent oil leakage are also earned our customer’s appreciation.

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.




  • Applications of the Pressure Conveyance
  • Pressures Applied:0 ~ 1 kgf/cm² 15 ~ 300HP
  • Special order with specific designs




  • 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.
