• The Titon Ultimate® Active Vent maintains consistent airflow by adjusting to changes in internal and external pressures
  • The vent’s vane automatically adapts to high wind pressure and gusts, ensuring indoor air comfort
  • The rotational vane balances airflow, preventing impact noise when exhaust apertures are fully closed off
  • Can be installed alongside intermittent, decentralised and centralised extract fans
  • High rotational sensitivity
  • Responsive at low air flows
  • Manual shut off
  • Easy screw-fix installation via hinged covers
  • Quiet action and fully automated
  • Specifically designed to work in conjunction with the energy efficient constant flow Titon Ultimate® dMEV

How it works

LOW wind pressure MEDIUM wind pressure HIGH wind pressure
Natural ventilation occurs in either direction at low pressure differentials. Control begins at airflows as low as 5m3/h
As the external pressure increases the vane reacts and closes the exhaust aperture accordingly reducing the incoming airflow whilst maintaining comfortable ventilation. At maximum pressure difference the vane will close the exhaust aperture preventing high airflow from entering the property whilst maintaining comfortable ventilation.

Why do we need Active background ventilators?

Titon Ultimate Active Vent

Background ventilators are a safe and energy efficient way of providing fresh air. Movement of air helps disperse general moisture in other habitable rooms (besides bathrooms and kitchens); if the moisture doesn’t escape, it can build up, leading to potential mould growth problems, affecting not only occupants’ health but also damaging the building itself.

Traditional background ventilators require human intervention to adjust the opening to match outside weather conditions and to maintain adequate ventilation. Often, people are unaware of this and the ventilators are left in the closed position with consequential poor indoor air quality.

The volume of air flow through the ventilator can increase significantly in windy conditions. More airflow leads to discomfort in cold weather conditions and heated air loss, this can lead to the ventilator being closed.

What is an Active ventilator?

The passive Titon Ultimate Active Vent technology, which has been developed by and is soley available from Titon, means a ventilator which automatically controls air flow, both into and out of a dwelling while at all times meeting the ventilator size requirements of all UK building regulations and technical standards.

A revolutionary new design, the technology is not too be confused with basic pressure control or self-regulating ventilators already available. These may shut off completely and therefore not control flow into and out of the dwelling.
