Figure 5-1 – Typical Blower Installation
A blower may be driven by direct-coupling to
the driver or by V-belt drive for the purpose of
obtaining other speeds within the approved
range.
See Motor Drives on page 19
for more
information.
Blowers 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 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 blower 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),
see Long-Term
Storage on page 29
.
Location
Install the blower in a room or outdoor area that
supplies adequate space and lighting for routine
maintenance. Make sure that indoor installation
areas are well ventilated and kept as cool as
possible, because operating the blower at elevated
temperatures can result in nuisance overload or
temperature shutdowns. An unprotected outdoor
installation is satisfactory only when correct
lubrication for the expected temperatures is
provided, as per
Recommended Lubricants on
page 42
.
Foundation
The blower does not need a special foundation.
However, it does require a solid, level
À
oor and
adequate frame support. Bolt the blower system to
the
À
oor and seal any cracks.
Blower Air Intake
To minimize maintenance, supply the blower with
the cleanest air possible. The air must not contain
any
À
ammable or toxic gases, as the blower will
concentrate these gases. This could result in
damage to the blower and surrounding property
and lead to personal injury or death. Do not block
or restrict the opening of the blower, as the motor
could overheat and fail.
Do not use blowers on explosive or hazardous
gases. Do not exceed the limits described in
Table
4-2 on page 9
on performance criteria such as
pressure differential, running speed, and discharge
temperature.
If it is necessary to take air from a remote source,
such as in a vacuum application, make sure the
diameter of the piping is at least equal to the
diameter of the blower inlet. For distances greater
than 20 ft (6 m), enlarge the pipe diameter to
reduce inlet restriction. Excessive restriction will
reduce the ef
¿
ciency of the blower and elevate its
discharge temperature. The piping used should
also be corrosion-resistant and free of scale and
dirt. Keep the inlet covered to keep out foreign
objects and rain. Vacuum kits are available.
