– 3 simple steps when calculating air amount
STEP 3Which air amount was the highest?You have now entered two different air amounts. The highest of the two numbers is the recommended amount of air for your house, see building regulation Bygningsreglementet BR2015.For example:The air amount according to Schema1 is 140m3/h or 39l/s.The air amount according to Schema 2 is 198m3/h or 55l/s.The last air amount is the highest one and is the one that suits your house best.
Are you allergic?People who suffer from allergies can benefit a lot from a ventilation system. The most common kinds of pollen particles are around 20-80µm, but some pollen particles, for example from forget-me-nots, can be as small as 2.5µm.If you choose an F7 filter for the intake, 99% of particles larger than 2.5µm will be removed.Particle size of other allergensFungus particles are around 2-20µm.

If the filters get blocked, it takes a lot of energy to force the air through, and some particles might be forced through.You can connect a filter alarm to the controls to remind you when to change it. To keep everything working optimally, you can also enter into a service agreement to have the system cleaned and the filter changed every six months.Need a filter?
