Description
APPLICATIONS
  • Supply and exhaust ventilation systems for various premises with high noise level requirements.

  • The VS fan design enables to assemble various ventilation configurations due to changeable positions of the removable panels.

  • Such design enables air supply in all directions, both linearly and at the angle 90 °C.

  • The aluzinc casing with high corrosion-resistant properties and heat-insulating material allows outdoor installation of the fan.

  • The fans may be integrated into an assembled supply ventilation system.

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 pipes are fitted with rubber sealing rings. 

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

MOTOR
  • 4- or 6-pole asynchronous external rotor motor and centrifugal impeller with backward curved blades.

  • The motors are equipped with overheating protection, which is connected to the external protection device (i.e., the model VS 355-4E has thermal switches with automatic restart).

  • The specially greased ball bearing motor ensures low noise and maintenance-free operation.
SPEED CONTROL
  • Smooth or step speed control with a thyristor or autotransformer speed controller.

  • Speed control is adjusted by the supply voltage regulation.

  • Air flow is regulated by the motor speed.

  • Several fans may be connected to one speed controller provided that the total power and operating current do not exceed the rated speed controller parameters.

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

  • The fan are designed for inline mounting.

  • While connecting the fan to flexible connectors, provide its fixing to a building with supports, suspension or fixing bracket.

  • The fan 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.
