Rotary Positive Blowers COMPETITOR PLUS rotary blowers are designed to be interchangeable with equivalent sizes of Roots Universal RAI®, and many Sutorbilt® Legend® Series L and P blowers. COMPETITOR PLUS models are rated up to 15 PSIG discharge pressure or 16” Hg dry vacuum. Features Helical Gearing COMPETITOR PLUS blowers are timed with precision helical gears, keyed to the rotor shafts, not taper fit spur gears as offered by other manufacturers, which have greater backlash, and can slip and lose timing. Helical gears are also quieter, reducing mechanical noise. Material Specifications: Housing: Cast iron End Plates: Cast iron End Cover: Cast iron Rotors: Ductile iron Shafts: Ductile iron, cast integrally with rotors Bearings: Gear end - Double row ball, both rotors Drive end - Cylindrical roller on drive rotor Single row ball on driven rotor 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 Stronger Bearings All COMPETITOR PLUS 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 PLUS blowers offer design bearing life as much as 50% greater than models offered by other manufacturers. Rotors with Integral Shafts COMPETITOR PLUS 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. Model Size Reduced Noise Versions Available Many COMPETITOR PLUS models are available with trilobe rotors and specially tuned housing to reduce blower noise. Versatility COMPETITOR PLUS blowers can be field converted from horizontal to vertical flow, or vice versa, without any special tools or additional components. *Approximate shipping weight. All Competitor Plus blowers are factory tested to meet ISO 9001 registered quality standards. Rotors are dynamically balanced to meet ISO1940 Grade 6.3 specifications.
