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

Product Information

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. Internal grilles in white plastic, plaster, brass & stainless steel with built in fly screens. Plastic version has extra coverage for ease of retro fitting. The Passyfier Core 140 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.

escapes by diffusion through Passyfier Vents, which have been tested by ADAS for airflow rate versus applied Increase ventilation where practical, IE when cooking close the kitchen door and open the window, when showering or bathing do the same. 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.

Until recently very little research had been done to prove the effectiveness of PIV and yet it widely specified. The BRE recently set up a parallel study to investigate the performance of PIV systems and carried out trials in their Watford test house and field studies in 16 Welsh properties. The study concluded with the following key findings: 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. Our 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.

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 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.programmes or installed directly in newbuild. A typical house needs about four/five Passyfier units. Quite

Tip: Apply a bead of sealant around the perimeter of the opening to ensure a water-tight installation. Ensure that there is a good seal to the loft hatch. Many hatches are very poorly sealed and allow moist air to migrate into the roof space.
