Pressure ventilators

VENTAIR II TRDn and VENTAIR II differential pressure controlled ventilators are used to achieve a constant, proper quantity of fresh air to the rooms. Automatic pressure control stabilizes airflow performance and protects against excessive exchange of air during cold and windy periods, allows for the realization of the concept of controlled ventilation, ensuring comfort and healthy indoor climate with minimum heat energy consumption. They are used in rooms equipped with gravitational or mechanical exhaust ventilation.

Product Description

VENTAIR pressure ventilators are equipped with a self-acting flow controller (which responds to the pressure difference), thanks to which the amount of supplied air is constant and independent of weather conditions (wind, cold). In addition they allow manual adjustment of the air flow including a shut-off.

They belong to a group of slot ventilators mounted in the upper, horizontal profile of the windows. They consist of two elements - a canopy mounted on the outside, and a ventilator mounted on the inner side of the window. These elements are connected by a slot made in the window profile, allowing for the air to flow.

A self-acting (automatic) flow controller is located in the canopy. The regulating part is an aerodynamic piece of aluminum "floating" in a stream of flowing air. As the air speed increases the airfoil rises and rotates around the upper edge shutting the internal area of the passage. When the speed decreases the airfoil drops. The airfoil fulfills the function of a proportional and automatic flow controller providing a constant flow regardless of external conditions.

The canopy shields against the ingress of rainwater, it is also fitted with an insect net.

The internal regulator allows for a manual change of the flow through the use of a liftable flap. Manual adjustment can be performed directly by a knob of the driving mechanism (BS version) or with the help of cords with weights (L left handed version, P right handed version).

Both the canopy and the ventilator are made of pressed aluminum profiles merged with plastic components. The controller is additionally equipped with thermal and acoustic insulation.
