5 Description
5.1 General
• The fan conveys air in an axial direction from the intake side via the electric motor to the outlet side.
• The electrical connection is made through a terminal box installed on the outside of the housing.
• Jet fans – also known as impulse or induction fans – support the natural flow between the supply-air and extract-air zones.
They provide motion in regions with low airspeeds.
5.2 Intended Use
• The model AJR is intended for installation in underground and above-ground parking structures, to facilitate ventilation
where occupants may be exposed to elevated levels of harmful pollutants.
• The temperature of the air transported through the fan must not exceed the temperature range stated on the name plate.
• For optimum operation, the jet fan must be suspended from the ceiling in a horizontal configuration so that the intake and
outlet are unobstructed.
5.3 Incorrect Use
Incorrect use refers to using the fan in ways other than that described above (section 5.2). The following examples illustrate incorrect
and hazardous applications:
• Not suitable for Hazardous location environments (Class 1, Class 2, or Class 3)
• Not suitable for use in environments containing grease-laden air
• Not rated for re or smoke extraction
