•
Bearings: Spherical/cylindrical roller and ball bearing
combinations; minimum 100,000 hour design life.
•
Tri-Lobe Rotors: Involute contoured impeller profiles
for maximum efficiency.
•
Impeller/Shaft Rigidity: Reduces mechanical deflection
and vibration.
•
Oil Seals: Simple non-wearing
slinger type oil seals, provide
positive sealing in both oil
sumps. Unaffected by high
temperatures. No shaft wear.
•
Air Seals: Piston ring air seals
provide dependable non-wearing
operation to minimize air leakage past
the shafts.
•
Heavy-Duty and ribbed cast iron housing and
end covers: Reduce noise levels and increase heat
dissipation.
•
Versatile Mounting: Horizontal or vertical airflow
is easily achieved by relocating the removable
mounting feet incorporated in all models.
•
Splash Oil Lubrication: Assures improved bearing
life and operational simplicity.
•
Gas or air is delivered in an uncontaminated,
oil free state.
•
The unit may be coupled directly or driven
by V-belts.
•
Rotation of the impellers is synchronized by a
pair of timing gears having helical, hardened
and ground teeth.
