  • BIM
  • Exhaust ventilation systems for commercial, office and other public or industrial premises for various premises that require reasonable energy saving solutions and controlled ventilation systems.

  • The use of fans equipped with EC motors, provides significant savings in electricity consumption and is the most effective and modern solution in ventilation systems.

  • Such characteristics are especially important for application in public premises as banks, supermarkets, restaurants, hotels, residential premises or domestic spaces.
  • The fan casing is made from steel with polymeric coating (VKV EC).

  • The fans are equipped with high-efficient electronically-commutated direct current motors with external rotor and impellers with backward curved blades.

  • EC motor is free of friction and wear parts as a commutator and brushes. These components are replaced by a maintenance-free electronic circuit board.

  • EC motors are featured with high performance and well controllable speed range.

  • Premium efficiency reaching 90 % is a definite advantage of electronically commutated motors.

Integrated functions and control
  • The fan is controlled by an external 0-10 V control signal. The fan capacity is regulated depending on temperature, pressure, smoke level etc.

  • The fan has low energy consumption at any speed.

  • Maximum fan speed does not depend on the available current frequency and is suitable for operation both at 50 and 60 Hz.

  • Several fans can be integrated into a single computer-driven control system.

  • Custom designed software provides high accuracy control of the fans integrated into a network.

  • The LED-display of the computer shows all the system parameters and the operation mode can be set individually for each fan in the network.

  • VKV…EC fans are designed for mounting on the roof.

  • The mounting plate enables the fan installation on a level surface directly above a ventilation shaft or air duct and the holes on this mounting plate provide reliable rigid fixing of the fan to a static surface.

  • For connection of the fans to round air ducts use the following accessories: KKV damper, GVK flexible connector, FKV counter flange.

  • For mounting of the fans to flat surface use the mounting frame RKV.
