Passyfier® 230 - Sleeved Dehumidifier Vent - Rustic/Condensation Control

Product Information

It is important to realise that the release of moisture vapour pressure within a dwelling to avoid condensation does not require a specific ventilation rate.

water vapour produced in a short time scale in kitchens and bathrooms without the additional use of mechanical

continuous extract

The Passyfier Core 100 Vent provides an opening on a section of wall normal to the airflow direction with an effective area well in excess of the minimum requirement. Airflow through the opening is controlled automatically by the intervening mineral wool slab and thereby avoids undue draughts. Looking at Ventilation Strategy & Options Mould caused by ineffective ventilation and poorly insulated loft space.

The Passyfier Sleeved 75AB Vent provides an opening on a section of wall normal to the airflow direction. Airflow through the opening is controlled automatically by the intervening mineral wool slab and thereby avoids undue draughts. In my experience, mechanical extraction to the loft space would have little effect or benefit. You should focus on the following: Versatility: Passyfier vents come in various sizes, making them suitable for installation in habitable rooms such as bedrooms and living rooms.Passyfiers take advantage of the differential partial moisture vapour pressure that is normally higher inside an For the Passyfier 100 and Passyfier 140, you can create the opening using a Dry Core Bit (Use a 132mm size for Passyfier 100 and 162mm size for a Passyfier 140). This is a special drill bit that can be used to cut a clean, circular hole in the wall. Begin by marking the centre of the desired location for the vent on the external wall using a pencil or marker. Then, using the dry core, drill through the wall from the outside until you reach the inside surface. Insert the Passyfier Vent tube into the prepared opening, connect the internal plastic grille and the external cowl to the Passyfier vent tube, and fix to the wall surface following the manufacturer's instructions. Ensure that the vent is level and held firm in the opening. https://www.insulationsuperstore.co.uk/product/felt-lap-vent.html?msclkid=90848a0451d111343a62e9a446445ea3&utm_source=bing&utm_medium=cpc&utm_campaign=%5BAll%20Products%5D%20%5BCatch%20All%5D%20%5B14.02.19%20RL%5D%20%5BLP%5D%20PLA&utm_term=4579465931580105&utm_content=All%20Products

Kill any mould that exists on the floor, wall and ceiling surfaces with a good quality fungicidal wash before redecorating. Passyfier vents have no moving parts, making them incredibly silent and energy-efficient. Unlike electric or desiccant dehumidifiers, they don't require any electricity to function, relying instead on natural pressure differences. within a dwelling is always higher than on the outside during the condensation season, and the moisture vapourThe external diameter of the tube is 104mm so the core should be cut larger eg. 4.25” (107mm).
