Discover Variavent – an alternative to AR75
AIR VENTS
3/10/2025


In the new technological distribution, Variavent enters the scene as an improved version of the popular Renson AR75 ventilator. This solid, pressure-driven model is going out of fashion at the end of the year, and its place is taken by this fresh proposal.
What makes Variavent more modern?
Modern form and construction – its minimalist frame with simple lines fits perfectly into modern aesthetic interiors.
More airflow options – Variavent allows for airflow regulation at five levels, which is a step forward compared to the four-level AR75; the mechanism operates autonomously but can also be controlled manually.
Universal fit – installation possible on window glass, in aluminum, wooden, as well as PVC profiles; additionally prepared for installation in the transom.
Thermal insulation – has a thermal break, which improves energy efficiency and reduces thermal bridges.
Ease of hygiene maintenance – the interior of Variavent can be easily cleaned, and its mesh effectively blocks insects.
Variavent is a step into the future of window ventilation — it combines the valued functionality of AR75 with modern design, additional airflow regulation, and increased user comfort. It is the natural choice for those who want to prioritize innovation and elegance in one.
