LWS&I Windows and Doors

AIR INLETS

Thermal comfort and health of the house's inhabitants are a priority. The heat transfer coefficient and air tightness are determinants when purchasing windows, but it is worth remembering that the building needs adequate ventilation.

Air Inlet: AERECO EMM

  • A two-stream air ventilator, the flow of which depends on the relative humidity in the room.
  • It also allows for manual closing, causing only minimal airflow.
  • Air flow at 10 Pa: 5–30 m³/h.
  • Acoustic attenuation: Dn, e, w = 32 dB.

Air Inlet: AERECO AMO.

  • Self-regulating air ventilator by means of the pressure difference inside and outside the room.
  • Air flow at 10 Pa: 6–27 m³/ h.



  • Acoustic attenuation: Dn, e, w = 32 dB.

Air Inlet: BROOKVENT AIRA HY

  • Maintenance-free air ventilator, the flow of which is regulated depending on the humidity in the room.
  • Can be used with an anti-smog filter.



  • Air flow at 10 Pa: 5–35 m³/h.
  • Acoustic attenuation: Dn, e, w = 34 dB.

Air Inlet: BREVIS VENTAIR

  • The air ventilator is automatically controlled by the pressure difference, with the possibility of closing for minimal air flow.
  • Air flow at 10 Pa: 6–24 m³/ h.


  • Acoustic attenuation: Dn, e, w = 34 dB.

Air Inlet: SLIMLINE 2000

  • The diffuser is controlled by the differential pressure and is distinguished by its narrow design.



  • Air flow at 10 Pa: 15 m³/h.


  • Acoustic attenuation: Dn, e, w = 36 dB.

Air Inlet: REGEL-AIR

  • A rebate vent, which is placed in the inner part of the frame, makes it almost invisible when the window is closed.



  • This allows air to circulate at the point of installation.
  • Air flow (for two diffusers) at 10 Pa: 5 m³/h.
  • Acoustic attenuation: Dn, e, w = 34 dB.
