  APPLICATIONS
  Supply and exhaust ventilation systems for various rooms suitable for external surface mounting.
  For rooms with high noise requirements we offer units with silent modification (VKMz ... Q).
  DESIGN
  The fan body is made of galvanized steel.
  For easier connection and operation, the fan can be equipped with the power cord with plug ( VKMz ... R ).
  THE ENGINE
  The backward curved impeller is powered by a single-phase motor with external rotor and overheating protection with automatic restart.
  The motor features ball bearings for a long service life designed to last at least 40,000 hours.
  For precise characteristics, safe operation and low noise, each impeller is dynamically balanced during assembly.
  Motor protection class IP 44.
  SPEED CONTROL
  Smooth or gradual speed control with a thyristor or autotransformer speed controller (TO BE PURCHASED SEPARATELY).
  Multiple fans can be connected to one speed controller as long as the total power and operating current do not exceed the rated speed controller parameters.
