The Passyfier Core 100 Vent is a through-the-wall Core Dehumidifier Vent capable of transmitting up to 1 Litre of water vapour per 24 hours. Airflow through the opening is controlled automatically by the intervening mineral wool slab and thereby avoids undue draughts.
The Passyfier Core 100 Vent is suitable for use use is in habitable rooms where it operates continuously without noise and over a 24 hour period can extract a maximum of 1 litre of water/day even at low vapour pressures. For ventilation in smaller areas such as cupboards, wardrobes or box rooms, see the Passyfier 75AB Sleeved Vent.
The Passyfier Core 100 Vent requires a 132mm Core Bit for application.

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.
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.
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.
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.
Its main use is in habitable rooms where it operates continuously without noise and over a 24 hour period can extract a maximum of 1 litre of water/day even at low vapour pressures. For ventilation in smaller areas such as cupboards, wardrobes or box rooms, see the Passyfier 75AB Sleeved Vent.
It is easier to fit the Passyfier Core-100 Vent in existing clinker/concrete walls.
However, it will be necessary to install two Passyfier Core-100 Vents to achieve almost the same water vapour transmission as one Passyfier Sleeved-230 Vent.
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.
