Tri Lobe Blowers
Advantages:
The , because of having rotor tips disposed at 120o on each rotor, causes the rotor set to be much more resistant to angular deflection along it's length, than two lobed rotor sets, which have lobe tips disposed at 180o each - this extra "stiffness" provides less deflection at any load, thus minimizing possible rotor contact with both the cylinder and it's sister rotor during operation.
Oil Preventive Arrangement
Due to efficient & improved oil prevention arrangement, gas or air is delivered uncontaminated; oil free state unaffected by high temperatures. No shaft wear.
Splash oil lubrication
Assures improved bearing life and operational simplicity.
Tri-Lobe rotors
Involute contoured impeller profiles for maximum efficiency.
Air seals
air seals provide dependable non-wearing operation to minimize air leakage past the shafts.
Heavy-duty and ribbed housing
Reduce noise levels and Use of fins increases heat dissipation.
Gear
Rotation of the impellers is synchronized by a pair of timing gears having helical, hardened and ground teeth.
This same tip orientation provides for more even load distribution between the rotor and gear sets, while under normal load cycling - this feature enhances the life of the bearings and gears - the six smaller volume chambers per revolution of the Tri-Lobe vs. four larger chambers of the two lobe, increases the pulsation frequency, allowing pulsation magnitude to be limited, and reducing characteristic noise levels.
