Aircool® Ventilator

Passivent Aircool® is a range of controllable insulated wall and window ventilators primarily for installation in external façade in commercial buildings. Electrically actuated dampers provide controlled air intake and extract in natural (passive) ventilation systems and may also be used for air intake or extract in mechanical ventilation systems. They are particularly suitable for night cooling strategies where daytime heat build-up is dissipated from the structure during the night. They also have excellent weatherability which allows the units to remain open even in inclement weather conditions.

The Aircool is available as a standard version, a thermal version, an acoustic version (two options – single baffle and double baffle) and a hybrid air-mixing variants known as the Hybrid Plus2 Aircool
