PAS 3300 - Pure Air Shield

The PAS 3300 has been specially designed for large spaces. The basic setting on the PAS 3300 carries out five air exchanges* per hour at low noise level. The number of air exchanges is dictated by the number of people in the space, how long they have been in the space, the type of movement or activity performed by those people in the space and the presence, or absence, of an existing ventilation system.
