Product Details ＋

The Passyfier Sleeved 75AB Vent is a through-the-wall Sleeved Dehumidifier Vent.

The Passyfier Sleeved 75AB capable of transmitting up to 0.75 Litres of water vapour per 24 hours and are designed for use in smaller areas such as cupboards, wardrobes and box rooms.

Airflow through the opening is controlled automatically by the intervening mineral wool slab and thereby avoids undue draughts. Available in SIX colour options.

Description

Passyfier Sleeved 75AB Vent

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.

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 0.75 litres of water/day even at low vapour pressures.

Key Features & Benefits:

Maximum Water Vapour Transmission Per Kit = 0.75 Litres / 24 hours
Maximum Floor Area Guide Per Vent Kit = 5m²
Used In Solid, Cavity & Timber Frame Walls
Being Non-Mechanical Works Passively 24 Hours Per Day
Makes No Noise & Has No Moving Parts
Easy installation to replace an existing single airbrick wall vent kit (Cannot be used to replace an existing combustion air vent.)
Reduces Draughts & Heat Loss But Still Provides Ventilation
Costs Nothing To Run
Works At Peak Condensation Time
No Night Time Disturbance From Fans Or Compressors

Recommendations:

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 (See our ).
Install the Passyfier Vent at a high level in retrofit and new-build applications if possible.
Use the Passyfier Sleeved Vent Kit where ever practical to maximise the transmission of water vapour.

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.
