The GECCO ventilation system Published on: 17. 12. 2016 - 9:12

The little flap with IQ

A controlled exchange between outside and inside air is a prerequisite for a pleasant room climate and greater living comfort. That is why the automatic ventilation system GECCO (GEALAN CLIMA CONTROL) is now available as an option for our windows. The little flap with IQ reliably prevents annoying draughts and mould formation in window reveals. It turns your normal windows into ventilation windows, for your own personal optimum living climate.

The flap is open in normal position, allowing air to circulate freely. The flap automatically closes the ventilation duct as wind speeds increase to prevent unpleasant draughts. GECCO works fully automatically.

The GECCO ventilation system also meets all requirements from a technical point of view. Tests have proven that this type of air exchange does not result in any significant heat losses.

The benefits of GECCO

  • Optimum air exchange at normal air pressures
  • Minimal energy losses
  • Continuous basic ventilation
  • Patented, fully automatic ventilation control
  • No draughts at high wind speeds
  • Automatic operation rules out incorrect operation
  • High heat and sound insulation
  • No whistling noises caused by draughts
  • Low-cost
  • Avoids mould formation



It is fitted on the room side at the top edge of the window sash. As well as being used in new windows, the GECCO 3 can be retrofitted into existing windows.

The inflowing air enters the rebate via the GEALAN ventilation gasket (1) and flows through the GECCO 3 (2) into the room.

GECCO 4 is designed to be added into head extenders or in tall head jambs. It offers additional benefits like a pollen and fine particulate air filter and an insect screen.

The fresh air flows through the GECCO 4 (1) and directly into the room (2). There is also a rain cover available for the GECCO 4.
