Description
APPLICATIONS
  • Supply and exhaust ventilation systems for various premises suitable for external surface mounting. 
  • For premises with high requirements to noise level, we offer units in low-noise modification (VC…Q).
DESIGN
  • Fan casing is made of steel with polymeric coating. 
  • Various fan modifications for surface or flush mounting are available.
MOTOR
  • The plastic impeller with backward curved blades is powered by means of the single-phase motor with external rotor and overheating protection with automatic restart.
  • For some dimension types high-powered motors are available (VC…S). 
  • Motor is equipped with ball bearings for longer service life designed for at least 40 000 hours.
  • For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly.
  • Motor protection rating IP 44.
SPEED CONTROL
  • Smooth or step speed control with a thyristor or autotransformer speed controller.
  • 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
  • Fan is designed for surface wall mounting (VC…PN and VC…VN models) or through-the-wall mounting (VC…PK and VC...VK) depending on design modification.
  • The fan is mounted to the wall with the mounting plate.
  • The fan is powered through the external terminal box.
  • Electric connection and installation shall be performed in compliance with the manual and wiring diagram on the terminal box.
