  • The KSV ES ventilation units are designed for integration into supply ventilation systems requiring high cleaning of intake air and low-noise operation.
  • The fans are compatible with round air ducts Ø 100, 150 and 200 mm.
  • Corrosion resistant casing made of polymer coated steel, internally lined with sound-insulating layer.
  • The pre-filter and the electrostatic filter are installed at the unit inlet.
  • Power is supplied through the airtight terminal box inside of the casing.
  • The ventilation unit design provides convenient maintenance access to the internal parts.
  • The single-speed models are equipped with a four-pole asynchronous electric external rotor motors and centrifugal impellers with backward curved blades. The impellers are dynamically balanced. The motors are compatible with mains frequency 60 Hz.
  • The double-speed models (Duo) are equipped with asynchronous electric external rotor motors and centrifugal impellers with forward curved blades. The impellers are dynamically balanced. Double-speed control. The ball bearings enable a long operating life.
  • The motors are equipped with an integrated overheating protection with automatic restart.
  • The compact design offers the ideal mounting solutions for limited mounting space, including suspended ceiling mounting.
  • Wall or ceiling mounting is performed by means of the supplied mounting brackets.
  • The unit is designed for strict horizontal installation. A service access must be provided.
  • Single-speed models: smooth speed control with the external speed controller RS-1-400 (specially ordered accessory).
  • Two-speed models: smooth speed control with the external speed switch P2-10 (specially ordered accessory).
  • The service panel in the casing enables quick access to the filters.
  • Pre-filtering with a G4 filter.
  • Fine filtration with an electrostatic filter.
  • Electrostatic filter enables purification of air from fine dust and soot, spray, smoke and other particles with the size of 0.01 microns and less.
  • Max. filter cleaning efficiency 98%.
  • The electrostatic filters rely on gravity of oppositely charged particles.
  • The polluted air stream flows through the spray charging unit for the particle ionization.
  • As a result of the adsorption of the ions on the particle surface the ionized particles are moved by the airstream and accumulated on the collecting plates, which are oppositely charged.

  • The filter cleaning interval depends on the inlet air pollution density and may vary from 7 up to 21 days. 
  • The filter cleaning interval is determined according to the results of the visual inspection of the filters.
  • Vacuum cleaning is allowed.
