Air filter
The Airtech Air+ is provided with G4 filters which are suitable for removing airborne
contaminants such as pollen and dust.
Where improved filtration is required optional F7 filters can be used. These filters
are effective at removing finer particles such as particulate emissions from diesel
engines. In urban areas close to main roads F7 filters are advisable in order to
ensure the supply air is clear of these particles which are potentially harmful to
health.
Where F7 filters are fitted, please ensure the flow rate of the fan is as expected. F7
filters cause extra system resistance so it may be necessary to increase the fan speed
to compensate
