Rotary Positive Blowers

COMPETITOR PLUS rotary blowers are designed to be

interchangeable with equivalent sizes of Roots Universal

RAI

, and many Sutorbilt

™

Series L and P blowers. COMPETITOR PLUS

Legend

models are rated up to 15 PSIG discharge pressure or 16" Hg

dry vacuum.

In addition to interchangeability, M-D has improved on

existing designs with the following superior features ordinarily

found only on premium blowers:

Helical Gearing

OMPETITOR PLUS 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, reducing mechanical noise.

Stronger Bearings

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 an average design

bearing life of up to 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. 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 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, M-D goes the distance to insure that your

blower meets our rigid ISO 9001 registered quality standards.

California Series B and F, and

ISO 9001 Registration

COMPETITOR PLUS blowers are manufactured under M-D's

ISO 9001 registered quality assurance program, the first

American manufacturer of rotary blowers to gain such

international recognition.

Warranty

Every COMPETITOR PLUS blower is backed by M-D's limited

warranty for a period of 18 months after installation or 2 years

after original blower shipment, whichever occurs first.

Versatility

COMPETITOR PLUS blowers can be field converted from

horizontal to vertical flow, or vice versa, without any special

tools or additional components.

Metric Availability

All COMPETITOR PLUS blowers are available with metric drive

shaft and process connections.

Page 6: Introduction
INTRODUCTION CONGRATULATIONS on your purchase of a new Tuthill Pneumatics COMPETITOR PLUS Rotary Positive ™ Displacement Blower from Tuthill Pneumatics Group. Please examine the blower for shipping damage, and if any are found, report it immediately to the carrier. If the blower is to be installed at a later date make sure it is stored in a clean, dry location and rotated regularly.
Page 7: Installation
INSTALLATION WARNING: Customers are cautioned to provide adequate protection, warning and safety equipment necessary to protect personnel against hazards involved in the installation and operation of this equipment in the system or facility. Do not use air blowers on explosive or hazardous gases. Casing pressure must not exceed 25 PSIG (1.72 bar g). Each size blower has limits on pressure differential, running speed, and discharge temperature, which must not be exceeded.
Page 8: Lubrication
LUBRICATION The bearings at the drive shaft end of the blower are grease lubricated. The timing gears and bearings at the other end are lubricated by the lower timing gear (when in the horizontal flow configuration) acting as a oil slinger, carrying oil to the upper timing gear and providing splash lubrication for the bearings.
Page 9: Preventative Maintenance
PREVENTATIVE MAINTENANCE A good maintenance program will add years of service to your blower. A newly installed blower should be checked frequently during the first month of operation, especially lubrication. Check oil level in the gear housing and add oil as needed. Complete oil changes are recommended every 1000 operating hours, or more frequently depending on the type of oil and oil operating temperature.
Page 10: Troubleshooting
TROUBLESHOOTING Although COMPETITOR PLUS blowers are well designed and manufactured, problems may occur due to normal ™ wear and the need for readjustment. The chart below lists symptoms that may occur along with probable causes and remedies. SYMPTOM PROBABLE CAUSE REMEDIES Loss of oil.
Page 11: Recommended Shutdown Procedure
RECOMMENDED SHUTDOWN PROCEDURE TO MINIMIZE RISK OF FREEZING OR CORROSION When high humidity or moisture is present in an air piping system, condensation of water can occur after the blower is shut down and the blower begins to cool. This creates an environment favorable to corrosion of the iron internal surfaces, or in cold weather, the formation of ice.
Page 12: Disassembly And Inspection
DISASSEMBLY & INSPECTION With proper maintenance and lubrication, normal life expectancy for gears, bearings, and seals can be achieved. However, over a period of time these parts must be repaired or replaced to maintain the efficiency of your blower. This section is written in a way that will allow you to completely disassemble your blower. The inspection of certain repairable or replaceable parts is referred to at the point of disassembly where these parts are exposed.
