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.

Performance Specifications:

Pressure range: up to 15 PSIG (1.03 bar g)
Vacuum range: up to 16" Hg (540 mbar g)
530 CFM @ 3600 RPM

Material Specifications:

Housing: Cast iron
End Plates: Cast iron
End Cover: Cast iron
Rotors: Ductile iron
Shafts: Ductile iron, cast integrally with rotors
Drive Shaft: Ductile iron, cast integrally with drive rotor
Gears: Heat treated alloy steel, helical cut
Seals: Lip seals on rotor shafts and drive shaft
Lubrication: Oil splash on gear end, grease on drive end

Bearings:

Gear end: Double row ball, both rotors
Drive End: Cylindrical roller on drive rotor, Single row ball on driven rotor

Helical Gearing		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.

Double Row Ball Bearings		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.

Positive End Clearances		Eliminates the risk of shifting end clearances when installing or removing drive components.

Polished Sealing Surfaces		All shaft surfaces in contact with sealing members are polished to reduce seal wear and risk of leakage.

Individually Tested		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.

This can be used an exact drop in replacement for Dresser Roots URAI #47 vacuum blower (same footprint, same dimensions, same port openings). Shaft diameter is 7/8".

Model 4007 Performance Curves

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.

Every Tuthill blower is backed by the Tuthill Vacuum & Blower Systems limited warranty:
