Description
Description
APPLICATIONS
  • Supply and exhaust ventilation and air conditioning systems of various premises requiring cost-saving controllable ventilation. 
  • The best ventilation solution for exhaust ventilation of bathrooms, kitchens and other humid premises.
  • Compatible with Ø 100, 125, 150, 200, 250 and 315 mm round air ducts.
DESIGN
  • Durable, impact-resistant and corrosion-free ABS-plastic casing.
  • Airtight terminal box for connection to power mains. 
  • VK … EC P is fitted with a built-in smooth speed controller and power cord with IEC C14 electric plug.
MOTOR
  • 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 external 0-10 V control signal.
  • 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 fan is compatible both with 50 or 60 Hz power mains.
  • 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.
MOUNTING
  • 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.
