    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.
