Features::
1. Quietness:because of its submergibility under water, so there will be not much noise from the machine when in use.
2. No need of a silencer:because of its under water, the created noise will be very low, so there will be no need to do silencer. Under-water can mean space-saving.
3. Strong structure, be relieved:the direct connect between the motor and the blower can avoid the inconvenience of traditionally-done belt adjustment.
4. Lower energy consumption:trundean roots blower are designed to control backflow pressure to the rotor in order to reduce energy consumption.
5. Longer bearing life:less vibration transmitted through the lobe results approximately 20% longer bearing life.

Features: 1. Lower noise:pressure pluses are the major noise source in blowers. The trundean roots blower design can efficiently reduce noise by approximately 5 db. 2. Lower energy consumption:trundean roots blower are designed to control backflow pressure to the rotor in order to reduce energy consumption. 3. Longer bearing life:less vibration transmitted through the lobe results approximately 20% longer bearing life. -

Roots blower Bore: 50~500mm Flow capacity: 0.5~420m3/min Pressure rise: 9.8kpa~98.8kpa Vacuum: -49kpa Roots blower, sometimes called a positive displacement, or pd blower, is a machine which "pushes" a relatively constant volume of the gas handled at the inlet through to the discharge. It applies to conditions requiring high vacuum or high pressure especially in the waste water treatment plant. The main purpose of the blower is to provide constant flow of gas at different pressures. The blower consists of a cast iron casing in which two rotors with conjugate shapes rotate and are synchornised by a set of timing gears. During rotation, there is no contact between the lobes or between the lobes and the casing.
