Rotary Positive Blowers

COMPETITOR PLUS rotary 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, 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.

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.

Worldwide Sales and Service
