AWENTIS II is used when one or two rooms are to be ventilated.

Advantages from operating the AWENTIS system:

• The ventilation process is not stopped if the ventilator is off (e.g. during a blackout) because the air is continually exchanged through the screened opening (gravitational ventilation).
• The ventilator does not need to be switched on for the ventilation system to operate properly. Lower electricity bills and total silence are undeniable advantages.
• The ventilator may be switched on and used instead of the screened duct if the air is to be exchanged more quickly.
• Unfavorable atmospheric conditions may render the gravitational ventilation useless. The ventilator may be switched on to ensure proper operation of the ventilation system.
