Applications:
Mechanically Assisted Ventilation Systems are suitable for dwellings, commercial buildings and flats, where, due to the room layout or the number of extract points required, PSV systems are impractical. They have the additional advantage that all extract ducts can be vented through a single roof terminal.

Authority:
Mechanically Assisted Ventilation systems are recognised by the BRE and are included in the revised Building Regulations England and Wales Approved Document F1: 1995 and Scotland Approved Scottish Technical Standard 3 2005 as an effective alternative to traditional methods.

System Design:
Mechanically Assisted Ventilation systems incorporate the whole house ventilation concept of PSV systems. However, the addition of a 'quiet running' fan unit increases flexibility of design and allows more complex requirements to be met.
The fan unit, which is generally located in the loft space (or a convenient cupboard), eliminates noise or vibration annoyance and ensures optimum performance.
As with PSV systems, Ubbink offer a complete design service, providing a customised ventilation system to meet the specific requirements. The design service offers specifiers the guarantee of an effective ventilation system that conforms with all relevant Building Regulations and individually specified criteria.

Control:
Mechanically Assisted Ventilation systems incorporate a manually operated speed controller (normally sited in the kitchen area). The controller has three settings: regular setting is suitable for everyday conditions, boost can be used when internal activities such as cooking etc. generate unusual levels of moisture. There is also an economy setting for background ventilation.
Humidity control options are also available for Mechanically Assisted Ventilation systems.

Building Regulations:
The Building Regulations England and Wales Approved Document F1 :1995 and Scotland Approved Scottish Technical Standard 3 2005 recognises the benefits of Mechanically Assisted whole house ventilation systems as an alternative to mechanical fans and provide guidelines for their use.
