VENTS VKH 355 EC

The fans are rated for exhaust ventilation and air conditioning systems 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.

The fan casing is made of galvanized steel (VKHz EC), aluminum (VKHA EC) or from steel with polymeric coating (VKH 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.

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.

VKH…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.

While mounting the VKH...EC fans to the level surface provide a support to exclude possible water or snow ingress into an exhaust vent of the respective ventilation shaft.

While installing the fan provide enough space for maintenance works.

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.
