5 Description
5.1 General
◊ Centrifugal design: As installed, the fan conveys air in an upward direction from the intake side, via the electric motor, to the
horizontal outlet where the air is forced downward at an angle.
◊ Jet fans – also known as impulse or induction fans – support the natural ow between the supply-air and extract-air zones. They
provide motion in regions with low airspeeds.
5.2 Intended Use
◊ The IV50-EC is an induction jet fan intended to operate in an enclosed vehicular facility where occupants may be exposed to elevated
levels of harmful pollutants.
◊ Rated for continuous duty.
◊ The temperature of the air transported through the fan must not exceed the maximum ambient temperature stated on the
nameplate.
◊ For optimum operation, the jet fan must be suspended from the ceiling in such a position 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.
5.4 Type key
The following table shows the model name breakdown for the Jet Fan products in this manual:
◊ Do not stack the fans on top of one another after uncrating.
◊ Use hoisting and/or lifting equipment that is suitable for the weight to be vertically moved.
Preconditions:
◊ Store the devices in a clean, dry and vibration-free environment.
◊ Storage temperature should be between –20°C and 60°C.
Storage for more than 3 months:
◊ Turn the impeller at least 10 revolutions, once per month.
o Please ensure that the impeller is at a different position afterward.
Storage for more than 12 months:
◊ Contact Systemair. We recommend an inspection by Systemair or its representative before commissioning.
