Air volume & air exchange

Air purifier for rooms up to 220m²

AIR VOLUME / REQUIRED DEVICE SIZE

LUFTVOLUMEN / ERFORDERLICHE GERÄTEGRÖßE

Each environment must be evaluated individually!

The number of 3 air changes per hour is recommended as an absolute minimum for a quiet area, significantly more frequent air changes are required in busy areas. A minimum of 6 air changes is recommended for normal public traffic, 10 air changes and higher for heavy public traffic and sports.

The specification of the air volume in m³ cannot be understood as well as the specification for the air cleaning related to the room area (m²). That is why we always like to use an example: For example, units from other suppliers start with a capacity of 80 m³/hour. With a ceiling height of 2.50 m, the air on 32 m² would be exchanged 1 x per hour. With the minimum exchange of 3 x per hour only 10.66 m² remain, with 6 x exchange only 5.33 m² - this would not even be enough for a toilet room.

Now an air purifier of the ETS Group for comparison: With our air purifier AP-90, with a performance of 720 m³/hour we reach purely mathematically with a ceiling height of 2.50 m with one complete cleaning of the rooms air 288 m² and with 3-fold cleaning 96 m² - this result is rounded off the number in the model designation.

Below are some examples assuming a ceiling height of 2.50 m (values rounded) for reference:
