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.
5.1.1 IV Smart EC
The IV Smart EC is a centrifugal jet fan driven by two EC motors, which can be controlled via an analog 0-10V signal, PWM signal, or
jumpered to run at full speed.
5.1.2 IV Smart EC - Modbus
The IV Smart EC - Modbus is a centrifugal jet fan driven by two EC motors which can be controlled via a digital Modbus signal.
5.2 Intended Use
◊ The IV Smart EC Series fans are induction jet fans intended to operate in an enclosed vehicular facility where occupants may be
exposed to elevated levels of harmful pollutants.
◊ Fans are 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. Fans are:
◊ 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.
◊ 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.
