Ventilation is driven by negative Pressure in the Room

VengSystem offers a range of ventilation systems. The most common is a system with negative pressure in the room. Other possibilities are system with neutral pressure, positive pressure or natural ventilation (no fans, ACNV).

A system with negative pressure has an air intake, which can be fixed (diffuse ceiling) or motorized inlets in wall or ceiling. The air outlet is typically a “chimney” with a fan and a shutter, which always is motorized at VengSystem. The controller sets the air intake and the air outlet to the best individual position, which is a progressive shutter in the air outlet and a delayed air intake, all balanced to get the right negative pressure at all air flows.
