Broan-NuTone 353 Gable Mount Ventilator 1020 CFM

The Broan-NuTone 353 Gable Mount ventilator is for ventilation to expel hot, stale air from a building used in HVAC systems. It has an airflow capacity of 1020 CFM and is mounted on the gable end wall of the attic. It works by sucking fresh air from the attic as well as pushing stale air out of the home constantly. This ventilation helps eliminate heat build-up and therefore decreases the cooling load on the home's heating ventilation and air conditioning system and may therefore result in reduced energy expenses.
