Series Vents VK EC

Series Vents VK EC - Centrifugal - Inline Fans
Supply and exhaust ventilation and air conditioning systems of various premises requiring cost-saving controllable ventilation
  • Motor type: EC
  • Impeller type: Centrifugal backward curved blades


  • The best ventilation solution for exhaust ventilation of bathrooms, kitchens and other humid premises.
  • Compatible with Ø 4” up to 12” round air ducts.


  • Durable, impact-resistant and corrosion-free ABS-plastic casing.
  • Aerodynamically shaped casing.
  • Airtight terminal box for connection to power mains.


  • High-efficient electronically commutated direct current motors with backward curved blades. Such motors are the most state-of-the-art energy saving solution. Power consumption of EC motors is 35 % less as compared to standard motors. The fans with EC motors have excellent aerodynamic performance and low-noise operation.
  • EC motors are featured with high performance and total speed controllable range.
  • High efficiency reaching 90 % is the premium advantage of the electronically- commutated motors. The motors are equipped with ball bearings designed for at least 40 000 operating hours.

Speed control

  • The fan is operated with an 0-10 V control signal. (ordered separately)
  • The air capacity is controlled depending on air temperature, pressure level, smoke content, etc.
  • The speed of the EC motor changes proportionally to fluctuations of the control parameter and the fan delivers a required air volume to the ventilation system. Maximum fan speed does not depend on the current frequency.
  • The fans may be integrated into a unified data processing control system. The specially designed software provides precise control of all the fans integrated into the system.


    • The fans are designed for duct mounting in any point of the ventilation system with the casing mounted at any angle. In case of vertical mounting a protective outer hood must be installed on the top.
    • Fixation to the floor, wall or ceiling is performed with the supplied mounting brackets.
    • Electric connection and installation must be performed in compliance with the manual and the wiring diagram on the terminal box.

    Mounting bracket for easy installation supplied with the fan
