3. Installation
As illustrated in Figure 1, the Airtech 3BA blower can be installed in any physical
configuration.
CAUTION! Regenerative blowers can have surface temperatures in excess
of 320° F. To avoid burns or other physical injury, take care to avoid
contact with the surfaces of the blower during and immediately after
operation.
To ensure adequate cooling of the blower during operation, install the blower with
the minimum clearance as indicated in the table below.
Minimum installation clearances, 3BA blowers
Range Distance from fan guard
to closest obstruction.
(inches/mm)
Distance from cover
(opposite of fan) to
closest obstruction.
(inches/mm)
3BA11 through 3BA14 1.4/34 0.79/20
3BA15 through 3BA19 2.1/53 1.57/40
3BA72 and 3BA73 1.3/34 1.18/30
3BA74 through 3BA76 2.1/54 1.18/30
Please note that it may be desirable, where possible, to allow for larger
clearances to allow access for maintenance or repair personnel. The noted
clearances are to ensure adequate air flow for cooling only and are a minimum
requirement.
Failure to allow for the noted clearances may result in premature failure of the
blower due to lack of cooling, even if all other precautions are taken as
recommended. For specific advice about installations requiring closer
clearances, please contact Airtech, Inc. for recommendations.
Airtech regenerative blowers can be mounted in any configuration, either
horizontally or vertically mounted. It is not usually necessary to bolt the smaller
blowers to a rigid surface during operation, though this may be desirable to
reduce pipe vibration, movement and noise. Larger models should be bolted in
place, especially when installed vertically, to prevent possible rotation, damage
or injury due to start-up torque.
CAUTION! For installations at altitudes greater than 3250 Feet above sea
level there will be a loss in capacity. Please contact your factory
representative for assistance in determining the extent of the loss of
capacity likely at your specific location.
