PPV Set-up Procedures
Single Blower Placement
When using one blower, it should be positioned so
that the cone of pressurized air
just covers
the
entrance opening
(Figure 5.1)
. If the blower is
too close to the opening, the opening will not be
completely covered by pressurized air. If the
blower is too far from the opening, pressurized air
will strike the building around the opening and
reduce the amount of pressurized air being forced
inside the building. Therefore, optimum
placement is dependent on the size of the entrance
opening, the size of the blower, and the distance
between the blower and the entrance opening.
Figure 5.1
Due to the size of the "cone" of air issued from a
blower, small blowers need to be moved back
from entrance openings while larger blowers
should be placed closer to entrance openings to
properly cover the opening with pressurized air.
By tilting blowers back about 17° maximum, the
entrance opening may be more effectively
covered with the cone of air. All Tempest
Blowers have "tilt-back” features to facilitate
operation. However, if a blower cannot be tilted
