Passyfier Dehumidifier Vents

About

The Passyfier Dehumidifier Vents range offers an effective solution for controlling indoor humidity levels without the need for mechanical systems. These through-the-wall vents work continuously and silently, making them ideal for use in habitable rooms, such as living rooms, bedrooms, and kitchens. Unlike mechanical systems, Passyfier vents rely on natural airflow principles, using a mineral wool slab to control the moisture vapour transmission rate. This ensures that moisture is efficiently removed from indoor environments without causing draughts, making them an excellent choice for both retrofit projects and new builds. The extended range now also includes heritage-sensitive and high-rise variants, along with an advanced external grille option for exposed elevations, so you can match performance and appearance to the building type and location. Why Use Passyfier Dehumidifier Vents? Excess indoor humidity can lead to issues such as condensation, dampness, and mould growth, all of which can compromise indoor air quality and the structural integrity of a building. Passyfier Vents help to prevent these issues by promoting the natural diffusion of moisture vapour through walls, maintaining a balanced humidity level without the need for powered ventilation systems. By extracting up to 2.3 litres of water per day in larger rooms, these vents are highly efficient while being energy-free and maintenance-free. Their non-mechanical operation makes them especially suitable for spaces where silent, continuous operation is required. In multi-storey properties where external access is difficult, dedicated high-rise models can be installed entirely from the inside to deliver the same passive humidity control without scaffolding. Key Features of Passyfier Vents The Passyfier range includes several models designed to meet different requirements. The Passyfier Sleeved 230 Vent is ideal for larger spaces up to 20m², effectively managing humidity with minimal heat loss. For smaller
