TAC air purifiers – which model for which purpose?

The possible applications of the TAC air purifiers depend on the contamination of the air by hazardous substances and the size of the room.

Various filters must be used depending on the level of contamination of the room air by hazardous particles. The use of individual filters or a combination of various filters of different classes may be necessary depending on the task, for example class G3 coarse dust filters, fine dust filters from class F7 or HEPA filters from class H13 for separating ultra-fine suspended matter.

You will find a practice-oriented guide to the filter classes and their specific use with regard to the type of room pollution in our comprehensive view of the different pollutant particle sizes.

Whereas coarse filters or fine filters can be used as individual filters, it is important to be aware that filters for suspended matter cannot. Hence if a HEPA filter is used, it is compulsory to use a fine filter in addition, which in this case serves as a pre-filter for the suspended matter filter.

The following table shows the cleansing capacities of the TAC models with regard to their degree of pollution (normal rooms, workrooms) and the different filter combinations:
