The Characteristic of the TRUN-DEAN Blower:
1. For traditional water-cooling blowers, the cog wheels can only be partly cooled, which can cause an ovenheat and break down the machine. And 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, so more safer, particulary in high pressure conveyance and the puffing air.
2. 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 shorten the life of the blower.
3. To reduce man-made errors, enhance the precision of the leave wheel, and to promote the blower efficiently, our rotor uses the most advanced one time work process Four-Shaft method.
4. Special design for reducing the body temperature by using water between the body and the casing.
5. Unique Design with Quality Components:
Appropriate clearance between the rotors and the rotors with the casing ensure no direct operational contact, hence no lubrication is necessary. The synchronous gear drive system and the shaft bearings are the only parts which require lubrication. Separate lateral chambers are designed to house these moving parts with proper seals to prevent oil leakage to the main chamber.
6. Low Noise & Minimal Vibration:
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 characteristics 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.
7. 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.

  • 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.
