INTRODUCTION
YOUR KEY TO TROUBLE FREE SERVICE
Thank you for investing in Sutorbilt quality. The Sutorbuilt 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 maintenance
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 for installing your blower. Follow the instructions carefully and you will be rewarded with trouble-free
Sutorbilt service year in and year out.

SECTION 1
EQUIPMENT CHECK
Before uncrating, check the packing slip carefully to
be sure all the parts have been received. All
accessories are listed as separate items on the
packing slip, and small important accessories such
as relief valves can be overlooked or lost. After
every item on the packing slip has been checked off,
uncrate carefully. Register a claim with the carrier
for lost or damaged equipment.
Customers are cautioned to provide
adequate protection, warning and safety
equipment necessary to protect personnel
against hazards involved in installation and
operation of this equipment in the system or
facility.
STORAGE
Your Gardner Denver Blower was packaged at the
factory with adequate protection to permit normal
storage for up to six (6) months.
If the unit is to be stored under adverse conditions or
for extended periods of time, the following additional
measures should be taken to prevent damage.
1. Store the blower in a clean, dry, heated (if
possible) area.
2. Make certain inlet and discharge air ports are
tightly covered to prevent foreign material from
entering the air box.
3. All exposed, non-painted surfaces should be
protected against rust and corrosion.
4. Provide adequate protection to avoid
accidental mechanical damage.
5. In high humidity or corrosive environments,
additional measures may be required to prevent
rusting of the blower internal surfaces.
6. To prevent rusting of gears, bearings, etc., the oil
reservoirs may be filled with normal operating oil.
Before running the blower, drain the oil and
replace to the proper operating level with clean,
fresh lubricant.
7. Rotate the blower shaft (10 to 25 turns) weekly
during storage. Inspect the blower shaft (near the
shaft seal area) monthly and spray with rust inhibitor
if needed.
8. For long term storage (over six (6) months),
contact Gardner Denver Compressor Division
Customer Service for recommendations.
REMOVING PROTECTIVE MATERIALS
The shaft extension is protected with rust inhibitor
which can be removed with any standard solvent.
Follow the safety directions of the solvent
manufacturer.
Blower inlet and outlet are temporarily capped to
keep out dirt and other contaminants during
shipment. These covers must be removed before
start-up.
The internal surfaces of all Sutorbilt units are mist
sprayed with a rust preventative to protect the
machine during shipment. Remove this film upon
initial startup, using any commercial safety solvent.
Position the blower so that the inlet and discharge
connections are in the vertical position (vertical
airflow). On vertically mounted units, it will be
necessary to lay the unit on its side supporting the
ends of the unit so as not to restrict the port on the
bottom side. Place a shallow pan on the under side
of the unit. With the blower disconnected from
power, spray the solvent in the top port, rotating the
impellers by spinning the shaft manually. Continue
this procedure until the unit is visibly clean.
Rotating components will cause severe
injury in case of personal contact. Keep
hands and loose clothing away from blower
inlet and discharge ports..
