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

Product Information

Note: Passyfier Vents are used as an aid to help control humidity and are NOT to be used as a method of providing ventilation to any gas, oil, or solid fuel appliance. They allow air to flow through a mineral wool slab in a controlled manner, tapping into the pressure differences between interior and exterior spaces to allow moisture-laden air to escape from your home. Installing Passyfier vents is relatively simple and can be done by most DIY enthusiasts without any professional assistance. The manufacturer provides detailed instructions with each vent, but here's a basic installation guide to help you get started. 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.

The diffusion process is slow compared with mechanical ventilation and would not cope with a copious amount of However, it will be necessary to install two Passyfier Core-140 Vents to achieve almost the same (albeit slightly more) water vapour transmission as one Passyfier Sleeved-230 Wall Vent. The diffusion process is slow compared with mechanical ventilation and would not cope with the copious amount of water vapour produced in a short time scale without the combined use of mechanical ventilation in kitchens and bathrooms.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. Tip: Apply a bead of sealant around the perimeter of the opening to ensure a water-tight installation. occupied building than on the outside . This pressure is completely independent of that in the air. For example, a

Passyfier 140 Core Vent: With a water vapor transmission capacity of up to 1.4 liters per 24 hours, this vent requires a 162mm diameter core and is suitable for rooms with a floor area not exceeding 10m².The Perma-vent passive air vent is environmentally friendly and requires no power, saving you money on your energy bills. It also has no moving parts and doesn’t require any maintenance. Passive Ventilation Products from Permagard 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.

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. The first step in installing Passyfier vents is to determine where you need them. Passyfier vents are ideal for installation in areas habitable rooms, such as bedrooms and living rooms. Keep in mind that the vents should be installed at a maximum distance of 12 inches below the ceiling height. In the absence of a modern whole house MVHR (mechanical ventilation and heat recovery) system, which few of us have, then your choices for how best to ventilate your property fall to single room options such as extractor fans or vents, or a PIV system may be recommended. The vast majority of properties that we deal with will rely on standard extractor fans, which more often than not are poorly chosen, poorly installed and poorly understood. General Principles for Ventilation

A typical house needs about four/five Passyfier units. QuiteIt is important to realise that the release of moisture vapour pressure within a dwelling to avoid condensation does not require a specific ventilation rate. Important Note: Passyfier vents must not be used for providing ventilation to gas, oil, or solid fuel appliances. 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 The opening where the Passyfier vent will be installed must be cleaned and prepared beforehand. Remove any loose debris, paint, or dirt and ensure that the surface is smooth and level.
