Assisted Ventilation

• BBA certified
Certified under certificate 96/3273, this offers assurance of a high quality performance and compliance with relevant building regulations.

• 24 hour ventilation
Provides 24-hour condensation control with continuous gentle extraction. This ensures that the dwelling will be continuously ventilated preventing condensation and giving a high level of indoor air quality.

• Range of controls strategies
The ventilation rate within the Passivent AV system is controlled by extract grilles located in wet rooms. A range of controls are available to suit the individual need of each project. Controls options include humidity control, motion sensing, timed boosts, and manual occupant controlled boosts.

• SAP Appendix Q eligible
Being SAP Appendix Q eligible, the Passivent AV system has been shown to reduce energy consumption compared to default SAP systems. By using the data from the Appendix Q database, the Passivent AV system can be used to improve SAP ratings compared with standard non-Appendix Q systems.

• Low energy DC fan
The A151DC fan which forms the central part of the Passivent AV system uses a DC motor which minimises electrical consumption, contributing towards a low energy whole house ventilation solution.

• Reduces background ventilation requirement when compared with standard extract fans
With the BBA certified Passivent AV system the requirement for background ventilation is one vent per room. This is far less than standard intermittent extract fans which require many more to comply with building regulations.

• Only one façade penetration per fan system
As there is only one penetration per fan system, this can greatly reduce noise penetrating the building envelope.

• 1 fan can serve multiple dwellings
This is ideal for multi-occupancy dwellings such as care homes, student accommodation and apartment blocks. This reduces energy consumption, running costs, and noise, when compared to systems which require fans in each dwelling.

• Ideal for apartment blocks, care homes & student accommodation
This is due to the fact that one fan can be shared across dwellings. This minimises costs and improves quality of life for occupants.
