Helical Gearing

COMPETITOR GT blowers are timed with hardened, precision
helical gears, keyed to the rotor shafts, not taper fit spur gears
offered by other manufacturers which have greater backlash,
and can slip and lose timing. Helical gears are also quieter,
further reducing mechanical noise.

Stronger Bearings

All COMPETITOR GT blowers include double row ball bearings
at the gear end, stronger than single row ball bearings offered by
other manufacturers. Drive shaft bearing is cylindrical roller type
for additional strength against side loading from V-belt drives.
As a result of this superior design, COMPETITOR GT blowers
offer significantly longer bearing life than models offered by
other manufacturers.

Rotors with Integral Shafts

COMPETITOR GT blowers include precision machined ductile
iron rotors with large, integrally cast shafts, not press fit and/or
pinned shafts offered by other manufacturers, which can loosen
over time and cause rotor clash. All rotors are dynamically
balanced for vibration-free rotation.

Positive End Clearances

End clearances are positively established at the blower gear end,
eliminating the risk of shifting end clearances when installing or
removing drive components. This also eliminates the need for
those special fork and saddle tools required by other brands to
reset end clearances.

Polished Drive Shaft Sealing Surfaces

Driveshaft is polished to reduce seal wear and risk of leakage.

The factory does not paint the blower.  

They only apply a light primer spray to slow down rusting.  

If you want us to take the blower out of the box and paint it, please let us know and we can do this for an extra fee.
