Outside-In: How the ASV brings fresh air into your home

ASV is made of tough ABS polymer. Can be cut to fit any wall thickness up to 14 inches. Outside air enters ventilator through a louvered grill, which provides protection from rain. Insects and vermin are excluded by a separate screen located directly behind grill.

Air flows into your house through an internal tube. Manually-operated damper controls airflow.
