Technical Details

Using a combination of the tried and tested range of ArrestAir-Pro Plus DiffuseAir products, this background ventilation version has been skilfully modified to ensure the internal grille has a closing plate and incorporates a fly mesh.

Having been fully tested the Building Research Establishment has determined the equivalent areas of ArrestAir-Pro Plus through wall assemblies opposite with circular ducting up to 150mm and rectangular ducting, up to a nominal size of 225mm x 150mm, to enable compliance with Building Regulations minimum requirements.

Although not shown the ArrestAir-Pro, being the external grille, and the DiffuseAir internal grille together can be used for upgrading existing wall vents to save energy and prevent draughts. For optimum performance ArrestAir-Pro and DiffuseAir should be fixed centrally over any wall duct.

The Building Regulations Require:

Table 1.7 From Part F Building Regulations June 2022 Minimum Equivalent Area of Background Ventilators For Natural Ventilation
Room Minimum equivalent area of background ventilators for dwellings with multiple floors Minimum equivalent area of background ventilators for single-storey dwellings
Habitable Rooms 8,000mm2 10,000mm2
Kitchen 8,000mm2 10,000mm2
Utility Room No Minimum No Minimum
Bathroom 4,000mm2 4,000mm2

Background ventilators should be sited to avoid draught, i.e. not less than 1.7m above floor level.
