The Feature of Longtech'sRoots Blower

Longtech three lobes Roots Blower are new series Roots type blowers. By CNC machine, we made precise rotors. Getting a perfect gap to promote air performance, lower vibrations and noises results a significant improvement compared to traditional Roots Blower of two lobes

Traditional Roots Blower lubricates bearings and gears with grease and oil but Longtech's is designed to add oil only. It is very convenient to maintain and oil has a better lubricating effect than grease. So it could be a longer bearings and gears life.

The Processes are as Follows:

1. air input
   
2. embraced by cylinder and rotor
   
3. air discharge.

Feature

1. LOWER ENERGY CONSUMPTION:
   Three lobes' design control backflow pressure to rotor so it can reduce energy consumption.
   
   
2. LOWER NOISE:
   Pressure pluses are the major noise source of blower.
   Three lobes' design can efficiently reduce noise by approximately 5dB.
   
3. LONGER BEARING LIFE:
   Less vibration transmitted through the lobe results approximately 20％ longer bearing life.
   (Conventional blowers result pressure pluses and vibration rob power and shorten the life of every bearing, gear and other drive train components.)
   
4. Wide range for air volume, pressure and vacuum.
   
5. Stable air flow and less pressure variation.
   
6. Clean air and without oil moist.
   
7. Construction simple and easy maintenance.
   
8. Bearings are all lubricated by oil moist
