Blauberg EC SB 550, with S14 controller

HRV unit for efficient energy saving supply and exhaust ventilation in flats, houses, cottages and other premises.Heat and humidity recovery minimizes ventilation heat losses during cold season and reduces air conditioner load during hot season.Controllable air exchange for creating the best suitable indoor microclimate. Compatible with round Ø 125, 160 or 200 mm air ducts


  • The HRV unit is equipped with high-efficient EC motors with an external rotor and a centrifugal impeller with backward curved blades.
  • EC motors have the best power consumption to air capacity ratio and meet the latest demands concerning energy saving and high-efficient ventilation.
  • EC motors are featured with high performance, low noise level and optimum control across the entire speed range.
  • The impellers are dynamically balanced.



  • The KOMFORT EC SB(-E) units are equipped with a bypass for ventilation (air cooling by the cool air from outside).



  • The casing is made of double-skinned polymer-coated steel panels, internally filled with 20, 25, 30, 40 mm (depending on the unit model) mineral wool layer for heat- and sound-insulation.
  • The unit is equipped with a hinged service panel to enable convenient access for maintenance or repair operations.
  • The spigots are located at the top of the unit and are equipped with rubber seals for airtight connection to the air ducts.


Air Filtration

  • The built-in F7 filter provides efficient supply air filtration. The G4 filter is used for extract air cleaning.
  • The G3 filters are used for supply and exhaust air filtration in the KOMFORT EC S(B)200units.
  • Supply air in the KOMFORT EC S(B)250 units is purified by the G4 and F7 filters. The G4 filter is used for extract air cleaning.
