Description
APPLICATIONS
  • Supply and exhaust ventilation systems for various premises with energy-efficient and low-noise requirements. 

  • The VS EC fan design enables both inline and 90° air outlet due to changeable positions of the removable panels.

  • The aluzinc casing with high corrosionresistant properties and heat-insulating material enables outdoor installation of the fan.
DESIGN
  • The fan casing is made of aluminium frame, fastened with aluminium bends and removable double-skinned aluzinc panels, heat- and sound-insulated with 20 mm non-combustible mineral wool.

  • The connecting pipes that also serve as vibration absorbing connectors are available with round and square sections.

  • The round connecting pipes are fitted with rubber sealing rings.

  • The connecting pipes are not included into the delivery set and are available upon separate order.

     

MOTOR
  • The impellers with backward curved blades powered with high efficient electronically commutated (EC) motors with external rotor.

  • As of today, such motor type is the most advanced solution for energy saving.

  • EC motors are featured with high performance and the optimal control over the whole range of fan speeds.

  • Premium efficiency reaching up to 90% is the absolute advantage of electronically commutated motors.

Built-in functions and control
  • The fan is controlled with the external control signal 0-10 V (air capacity as a function of temperature level, pressure, etc.).

  • Should the control value factor get changed the EC motor changes its speed and the fan boosts as much air flow to the ventilation system as required.

  • Maximum speed of the fan does not depend on the current frequency and it can operate at 50 or 60 Hz mains supply.

  • The fans can be integrated to the unified PC control system.

  • The respective software allows controlling all the fan units with high accuracy and setting particular operation mode for each fan.

MOUNTING
  • The fans are designed for connection to rectangular or round air ducts with a flexible connector of respective cross section.

  • The fan can be fixed with supports, suspension or mounting bracket and it is suitable for any mounting position, on condition that the pointer on the fan casing matches the air motion direction in the system.

  • While mounting the fan provide enough access for its servicing.
