Pressure controlled trickle vent TRDN II

Window vents enable efficient air circulation in the room and sustain optimal moisture. With window vents the air in the flat is fresh and our family lives in healthier environment. Our vents are an aesthetic and functional device designed for easy assembly.

They are dedicated to PVC and timber windows. Available in three popular colours: white, golden oak and brown. Mounted in the upper part of the window they prevent drafts. They can be used both in new windows and windows already fitted in the house. The body of the vent is made from high-quality aluminium, whereas drive unit elements are made from polyformaldehyde- with special attention to details and usage comfort.

Trickle vents TRDN II are elements of a ventilation system enabling proper air circulation:

• AUTOMATIC  AIR CIRCULATION REGULATOR  (reacting to the pressure difference)- air input is stable independent from weather conditions (wind, cold). AIR CIRCULATION REGULATOR – it is placed in the inlet probe. Aerodynamic aluminium sheet works as steering element “floating” in the stream of inflowing air.
• INLET PROBE – protects against rainwater absorption, equipped with an insect net.
• INTERNAL REGULATOR – directs air stream diagonally upward, enables manual regulation of air circulation by means of tilting flap
