Simple Design. Smart Control. Built for Effortless Fresh Air.
The Fresh Air Valve with Thermostat is a quiet embodiment of intelligent simplicity—a compact, self‑adjusting system that keeps indoor air fresh while reducing energy loss. No wiring, no motor, no electricity—just natural airflow guided by smart physics that adapts automatically to outdoor conditions.
At its core, a mechanical thermostat senses external temperature and adjusts airflow in real time. When it rises above +10 °C, the valve opens fully to deliver a steady stream of fresh air. As temperatures fall below –5 °C, it gradually closes, preventing cold drafts and protecting interior warmth. Built on precise thermal‑expansion mechanics, the design operates continuously without noise, electronics, or maintenance.
For added flexibility, the valve can also be closed manually—allowing quick, intuitive control over ventilation whenever needed. Compact, silent, and completely passive, it provides background fresh air that feels effortless day and night.
Ideal for homes, offices, kitchens, and meeting areas, the Fresh Air Valve with Thermostat offers sustainable comfort through pure mechanical intelligence—air renewal that quietly runs itself.
