Ventilation and filter system
The Negative Pressure Units are used to filter contaminated room air and to maintain negative pressure in contaminated rooms. Due to the negative pressure, no contaminated air can escape from the black area. All the air passes through the unit where it is filtered several times. In addition to preliminary and intermediate filters, a choice can be made between H13 and H14 class Hepa filters. The negative pressure units can be attached to airlocks or work tents.
