TRUNDEAN Machinery makes a good example on developing roots blowers for blower industry by launching the new Pressure Conveyance Roots Blower, which features Low Noise and Minimal Vibration.

 TRUNDEAN Pressure Conveyance Roots Blower - THL series adopts the most advanced method, One Time Work Process Four Shaft method, for processing blower impellers; not only it reduces human errors, but also enhances impellers precision and increases blower efficiency. The Pressure Conveyance Roots Blower is widely used in many kinds of industries, such as petroleum, metallurgy, power, mining, building material, chemical, fertilizer, paper-making, port, light industry, food, environment protection, aquatic farming, city gas and medicine, etc.

THL Type roots blower is one of the outstanding work made by Trundean Machinery Industrial Co., Ltd. in 90’. This roots blower’s air compartment and the side cover both are equipped with a flange and a groove rim, which help to enhance the THL Type roots blower's operational functions and prevent the eccentric phenomena happened when we fastening the stud.  Besides, each rotor keeps an appropriate clearance from others, and each rotor has the casing to avoid collision occurred in operation, thus there is no need to lubricate it. Only the synchronous gear drive system and the shaft bearings are the two parts need lubrication; but the separated lateral chambers are well designed to house these two moving parts with proper seals, so that it can prevent from oil leaking into the main chamber.

Moreover, noise decrease and vibration reduction are the main priorities in developing the new series of roots blower. THL Type roots blower (Pressure Conveyance) is no doubt the perfect combination of these two advantages. Trundean roots blower can efficiently reduce noise by approximately 5 dB, and its “Less vibration design” helps to prolong the bearing’s life by 20%. The specification of this THL TYPE blower is below:
