Ventilation based on negative pressure can be set up in many combinations. Fresh air enters the room through wall or roof vents, whereas air is drawn out of the room through ventilation canals with fan. This creates negative pressure.
We offer ventilation based on specific need – ventilation controlled as a minimum to set temperature and with possibility also to measure moist or gases to further optimize the ventilation.
For safety the system is delivered with 24 V emergency opening that controls the system in case of power failure and an alarm system with GSM transponder that warns system failure or alarm limits in the rooms that are ventilated.
