IV Jet Fans

      Compact, smart solutions for smoke extraction

      • Up to 400°C/120 min (F400)

      • Continuous medium temperature up to 45°C

      • Flexible

      Flexibility

      The IV Series jet fan is for daily ventilation requirements and smoke extraction in case of fire. The compact housing design is ideal for low ceiling heights. Depending on the model, the discharge direction from the integrated deflector can be adjusted.


      Reliability

      The casing is made out of galvanised steel for corrosion protection.

      The combination of casing and motor construction minimises the need for maintenance of the fans and allows long, continuous operation.

      Construction

      The casing is made of galvanized steel for best corrosion protection.

      Compact casing for thin ceiling height with variable outlet depends on the model.

      Impeller

      The IV fans use an aerodynamic radial impeller for maximum thrust and low noise emissions. These are made of galvanized steel or aluminium, dynamically balanced and paired with corresponding IEC motors with efficiency IE3 or EC motors.

      Motor

      Depending on the type, IV fans are designed with high-temperature motors for temperature classification (insulation class B or H) up to F400 (400°C/120 min) AC or EC Motors. The Motors are suitable for 50 Hz and 60 Hz.

      Motor protection

      Depending on the type, AC motors have integrated thermal protection with manual (electrical) reset, prewired integral thermocontact TK or thermistor PTC with leads to a motor protection device.

      Fans with EC motors have integrated electronic thermal protection, including locked-rotor protection and soft-start.

      Control

      EC motors with a built-in potentiometer to adjust the working point can also be controlled by external signal 0-10V.

      Depending on the type, EC motors are also equipped with Modbus communication or alarm signals.   

      AC motors can be controlled by a 5-step, stepless speed regulator, D/Y switch or frequency converter.

      Installation

      The IV jet fans are designed for horizontal installation.
