VENTAIR II TRDn, VENTAIR II i VENTAIR SIMPRESS air inlet vents controlled by means of the pressure differences serve to transfer the regular amount of fresh air to the rooms. The automatic pressure control stabilizes the air supply capacity, protects against extensive exchange of air in the winter and windy seasons, makes allowances for controlled ventilation assuring comfort and healthy atmosphere inside the room and the heat energy savings. They are applied in the rooms equipped with gravitational ventilation and mechanical air exhaust ventilation.
VENTAIR pressure air inlet vents are equipped with an automatic flow controller (reacting to pressure differences), thanks to which the amount of supply air is regular and independent of the weather conditions (wind, cold). Plus, it is possible to adjust and close it manually.
They belong to the group of slotted air inlet vents mounted in upper horizontal window structural profiles. They consist of two elements – intake vents mounted outside, and a controller mounted on the internal side of the window. These elements are combined by means of the slot in the window profiles, which assures a flow of air.
The automatic flow controller is located in the intake vent. The controlling unit is an aerodynamic aluminum plane “floating” in the stream of air. With the increase of airflow, the plane floats and rotates around the upper edge. When the speed decreases, the plane falls. It serves as a proportional automatic flow controller to assure a regular stream, regardless of the weather conditions.
The intake vent provides extra protection against rainwater penetration and is equipped with anti-insect net. VENTAIR pressure air inlet vents are equipped with automatic flow controller (the internal controller allows changing the flow manually thanks to the use of deflecting flap). The manual adjustment can be operated directly. With regard to VENTAIR II TRDn and VENTAIR II air inlet vents – by means of driving gear knob (BS version), while with regard to VENTAIR SIMPRESS air inlet vents – by a lever. VENTAIR II TRDn and VENTAIR II air inlet vents may be equipped with controllers with strings and weights (left-sided version L, right-sided version R). VENTAIR II TRDn and VENTAIR II air inlet vents are made of aluminum profiles combined by means of plastic elements. VENTAIR SIMPRESS air inlet vents elements are made of plastic in their entirety. All pressure air inlet vent models have thermal and acoustic insulation.
