Non-Mechanical, Low-Heat-Loss Vent for Passive Moisture Control. The Passyfier Vent is a passive ventilation unit designed to combat condensation build-up in problem areas such as bathrooms, kitchens, and utility rooms. It features a through-the-wall telescopic sleeve filled with mineral wool insulation, combined with a discreet internal louvre and external cover. This non-mechanical system works continuously without power or moving parts, allowing moisture-laden air to escape while preventing draughts and heat loss.. Key Features & Benefits. Effective Condensation Control: Reduces or eliminates surface condensation by enabling passive ventilation in high-humidity spaces.. No Draughts: Mineral wool insulation restricts airflow back into the room, eliminating cold draughts.. Energy Efficient: Allows vapour to escape without significant heat loss thanks to the insulating core.. Zero Maintenance: No moving parts or power required – the system works continuously, 24/7.. Discreet Design: Includes a louvered internal vent and a clean external cover for a low-profile appearance.. Product Details. Type: Passive through-wall ventilation unit.
