COMPETITOR PLUS™ blowers are designed to be interchangeable with equivalent sizes of Roots Universal RAI®, and many Sutorbilt® California Series B and F, and Legend™ Series L and P blowers. COMPETITOR PLUS models are rated up to 15 PSIG discharge pressure or 16" Hg dry vacuum. In addition to interchangeability, Competitor Blowers have superior features ordinarily found only on premium blowers - see table below.

Timed with hardedened, precision helical gears, keyed to the rotor shafts (NOT taper fit spur gears as offered by all other manufacturers, which have greater backlash, and can slip and lose timing). Helical gears are quieter, reducing mechanical noise. |

For increased strength compared to single row bearings offered by competing brands. This feature increases bearing life by as much as 50% compared to competing brands. |

- Rotors with Integral Shafts
|
|
COMPETITOR PLUS™ blowers are available in two-lobe or tri-lobe variations. The tri-lobe variation offers reduced pulsation and lower noise levels. The two-lobe variation is ideal for processes with heavy contamination. For vibration free operation all rotors are dynamically balanced. Shafts are integral to the rotors, which prevents loosening over time. |

- Polished Sealing Surfaces
|

Every COMPETITOR PLUS™ blower is factory tested to assure you of the highest quality. While some manufacturers perform only sample testing, we go the distance to insure that your blower meets our rigid ISO 9001 registered quality standards. |

Rotary Positive Gas Blowers
Designed with features found ordinarily on high-end
blowers, COMPETITOR GT blowers are still designed to be
interchangeable, with respect to foot print, shaft height and
diameter, with equivalent sizes of Roots Universal RAI-G®, and
many Sutorbilt® California Series Legend™ Series L and P, as
well as M-D Pneumatics COMPETITOR PLUS™ blowers.
Splash Oil Lubrication at One End
COMPETITOR GT blowers include splash oil lubrication at gear side and grease on shaft side.
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.
When you open the box all new blowers are rusted.
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.
