Piping should be accurately squared with the booster and supported independently. Stress imparted from
incorrectly aligned piping or mounting will create problems with bearing and seal life, possibly leading to
premature internal contact. The booster should sit stress free and evenly on its supporting surface. Care
should be taken to evenly tighten the mounting bolts to not impart undue stress into the booster. Stress can
be checked in a free state with feeler stock or veried on a previously installed blower with the aid of a dial
indicator. Less than .002” (.05 mm) spring or gap should be found.
A booster may be driven by direct-coupling to the driver or by V-belt drive, to obtain other speeds within
approved range. (See the Motor Drives section for more information.)
Boosters from Tuthill Vacuum & Blower Systems are internally and externally treated after factory assembly
and testing to protect against rusting in normal atmospheric conditions prior to installation. The maximum
period of internal protection is considered to be up to 6 months under average conditions, provided closing
plugs and seals are not removed. Protection against chemical or salt water atmosphere is not provided. Avoid
opening the booster until ready to begin installation, as protection will be quickly lost due to evaporation.
(For recommended preparations for long term storage (longer than 6 months), please see the Long Term
Storage section in this manual.)
5.1.1 LOCATION
Install your booster in a room or outdoor area that supplies adequate space and lighting for routine
maintenance. Indoor installation areas should be well ventilated and kept as cool as possible, because
operating the unit at elevated temperatures can result in nuisance overload or temperature shutdowns. An
unprotected outdoor installation is only satisfactory when correct lubrication for expected temperatures is
provided, as per the Recommended Lubricants section in this manual.
5.1.2 FOUNDATION
Your booster does not need a special foundation, however it does require a solid, level oor and adequate
frame support. Bolt the booster to the oor and seal any cracks.
5.1.3 BOOSTER AIR INTAKE
To minimize maintenance, supply your booster with the cleanest air possible. It is important that the air
does not contain any ammable or toxic gases, as the booster will concentrate these gases. This could
result in damage to the unit and surrounding property, lead to personal injury or death. Do not block or
restrict the opening or the booster and/or motor may overheat and fail.
Do not use boosters on explosive or hazardous gases. Each size booster has limits on pressure differential,
running speed, and discharge temperature. These limits must not be exceeded. Consult Table 1 for details
pertaining to the allowable performance criteria.
If it is necessary to take air from a remote source, such as in a vacuum application, the piping should be
at least the same diameter of the booster inlet. For distances greater than 20 feet (6 m) the pipe diameter
should be enlarged to reduce inlet restriction. Excessive restriction will reduce the efciency of the booster
and elevate its discharge temperature. The piping used should also be corrosion resistant, and free of
scale and dirt. The inlet should be covered to keep out precipitation, insects, and small animals. Vacuum
kits are available.
