INTRODUCTION
YOUR KEY TO TROUBLE FREE SERVICE
Thank you for investing in Sutorbilt quality. The Sutor-
bilt reputation for rugged dependability has been
earned by over 50 years of service in demanding,
industrial operations where downtime cannot be
tolerated and efficient blower performance is expected.
Your Sutorbilt blower is a precision engineered blower
that has been carefully manufactured and thoroughly
tested at the state-of-the-art Gardner Denver Blower
Factory in Sedalia, Missouri.
As with other precision machinery, there are several
relatively simple installation, operation and mainte-
nance procedures that you must observe to assure
optimum blower performance. There is no guesswork
in the manufacture of your highly advanced Sutorbilt
blower and there must be none in preparing the blower
to get the job done in the field.
The purpose of this manual is to help you properly
install, operate and maintain your Sutorbilt blower. It is
essential that you review all sections of this manual in
preparation for installing your blower. Follow the
instructions carefully and you will be rewarded with
trouble--free Sutorbilt service ...yearinandyearout.
OPERATING PRINCIPLES -- The 4500 Series rotary
blowers are the positive displacement type with two
figure--eight shaped impellers rotating in opposite
directions inside the casing. As each lobe of an
impeller passes the blower inlet, it traps a quantity of air
equal to exactly one--fourth the displacement of the
blower. This trapped air is forced around the case to
the blower outlet. Timing gears accurately position the
impellers in relation to each other to maintain the
minute clearances so vital to the high volumetric
efficiency of the rotary positive displacement blower.
