| AIR-JET
Models
AIR-JET units
are available in two distinct configurations, each
satisfying a particular requirement.The varying designs
allow the AIR-JET units to meet most installation
demands.
Model FA (100%
Fresh Air)
This unit possesses a single motorized
damper on the rear of the unit, which serves to allow
fresh air to enter the fan unit when functioning or
to inhibit infiltration when the unit is off. The
fan motor and damper motor are controlled by a customer
supplied and installed starter, which is normally
at the floor level. If required, the customer can
interconnect the AIR-JET system with other exhaust
systems. Units are completely prewired and require
only primary electrical connection. The two position
damper motor (open or closed) is equipped with an
emergency return function to ensure this damper closes
during a power outage. The FA unit brings 100% fresh
air into the building and thus would be selected when
there is an abundance of hot air available to offset
the incoming air during winter operation.
Model FA-R (Fresh
Air and Recirculation)
The FA-R unit is similar to the FA unit
with the following exceptions. A second mixing or
recirculation damper (Y) is provided within the fan
cabinet. The two dampers (X and Y) are interconnected
and controlled by a modulating damper motor and proportional
electronic thermostat. (Thermostat is located on the
fan housing if not otherwise requested). Unlike the
FA model which can take air only from outside, the
FA-R unit can mix fresh outside air with warm inside
air before being distributed in the building through
the air tube. The FA-R unit would thus be selected
where some tempering of outside air is required before
discharge into the building environment. Units are
completely prewired and require only primary electrical
connection. Emergency return of the damper motor to
the closed (shut) position is provided. |
SPECIFICATIONS:
Housing
Construction is 16 gauge galvanized steel. The housing
is equipped generally with two access doors giving
simple access to the units' components which may require
attention. Electrical terminal box is located on the
outside of the fan housing providing easy access for
electrical hookup, controls or maintenance.
Fan
An axial fan is employed in standard units, both statically
and dynamically balanced to ensure proper operation.
The fan blade sits on two industrial quality pillow-block
bearings. High pressure applications require an optional
blade which can be made available at an additional
cost.
Motor
Continuous use TEFC motors are used wherever practical.
Available voltages are 115/230/1/60 or
208/230/460/575/3/60 for 1/3, 1/2, 3/4 or 1 HP motors.
Available voltages are 208/230/460/575/3/60 for 3,
5, 7.5 HP motors.
Motorized Dampers
Constructed of industrial quality galvanized steel,
the fresh air damper provides minimum leakage with
gap seals. Optional insulated air foil dampers are
available at an additional cost.
Tube
AIR-JET air discharge tubes are fabricated
to meet each individual application. Constructed of
high density polyethylene fabric which is coated on
both sides, this material meets government self-extinguish
requirements. Tubes are perforated as required and
available in standard configuration or dual mode (summer/winter). |
