It works on the scientific principle that when the room temperature and humidity are greater internally than externally, moist air will be ventilated outside the building due to vapour air differences. Important Note: Passyfier vents must not be used for providing ventilation to gas, oil, or solid fuel appliances. Passyfiers take advantage of the differential partial moisture vapour pressure that is normally higher inside an Increase ventilation where practical, IE when cooking close the kitchen door and open the window, when showering or bathing do the same.

Use the compatible wind blast cowl, with every vent in exposed or coastal locations. Use in conjunction with mechanical extraction in kitchens and bathrooms. 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. Energy-Efficient: Passyfier vents are incredibly energy-efficient, requiring no electricity to function. They rely on natural pressure differences instead, making them cost-effective and environmentally friendly. PIV did not directly save any energy but may save a little when compared to conventional extraction providing the same level of ventilation exchange. This is because roof space temperatures are usually a minimum of 3OC higher than outside.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 The Passyfier Sleeved 230 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.

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 moisture vapour pressure within a dwelling is always higher than the outside pressure therefore there will always be an escape of moisture vapour by the diffusion process through the Passyfier Vent. escapes by diffusion through Passyfier Vents, which have been tested by ADAS for airflow rate versus appliedOur Passive Ventsare a form of natural ventilation and work on this scientific principle. When the room temperature and humidity are greater internally than externally, moist air will ventilate outside the building due to vapour air differences. This pressure-driven ventilation reduces condensation and helps prevent mould growth. programmes or installed directly in newbuild. A typical house needs about four/five Passyfier units. Quite Integrated Fly Screen: Passyfier vents come equipped with an internal white plastic grille with an integrated fly screen to keep insects at bay.

In the field monitored houses input ventilation was not consistently effective in reducing relative humidity. When internal humidity levels over those outside was examined, PIV was found to be effective in the most humid houses but did little in the dryer houses. Even in the cases where it was effective there were often inconsistencies between rooms in the same house. Looking at Ventilation Strategy & Options Mould caused by ineffective ventilation and poorly insulated loft space. For ventilation in smaller areas such as cupboards, wardrobes or box rooms, see the Passyfier 75AB Sleeved Vent. Tip: Apply a bead of sealant around the perimeter of the opening to ensure a water-tight installation.Use the Passyfier Sleeved Vent Kit wherever practical to maximise the transmission of water vapour. The best solution is an air heat recovery unit which heats up incoming fresh air using the warm stale humid air which it exhausts at the same time. The unit contains a matrix through which the warm humid air from your property is directed as it is extracted to the outside. The fresh but cold external air is then pulled in accross this matrix warming it up and giving you pre heated fresh air into your home or property. These fans are now up to 92% efficient at heat recovery and 90% efficient for power consumption. These units efficiently combat condensation and improve air quality within the home. Some units cost less than a lightbulb to run. The unit is designed to be very unobtrusive, with a 6" (152mm) internal white plastic grill. Externally all that can be seen is a 6" white plastic external grille.

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. Condensation is a complex subject, primarily ventilation is the answer but this can be problematic in the cold eg during winter. There are lots of opinions on prevention but as a fully trained and qualified surveyor I can confirm that every property is different. 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. Allow one vent per cupboard / wardrobe space or box room with a maximum floor area not exceeding 5m². Kill any mould that exists on the floor, wall and ceiling surfaces with a good quality fungicidal wash before redecorating.Kill any mould that exists on the floor, wall and ceiling surfaces with a good quality fungicidal wash before redecorating (See our Mould Eradication Range). Passyfier 100 Core Vent: With a water vapor transmission capacity of up to 1 liter per 24 hours, this vent requires a 132mm diameter core and is suitable for rooms with a floor area not exceeding 7m². With the airtightness of newer properties and the new building regulations where new properties must pass an air tightness pressure test, extractor fans may not be suitable, they can create a negative pressure which stops them working effectively. PPU's or positive pressure units are great in summer but in winter they are forcing minus degree air into your home, this can result in freezing hall landing areas.
