A dependable supply of outdoor air is one of the foundations of good indoor air quality. The Fresh Air Ventilation System by Wadbros is designed to introduce fresh outdoor air into occupied spaces while supporting the removal of stale indoor air. Fresh air ventilation can be particularly important in buildings with limited natural airflow or tightly sealed envelopes. Modern construction methods often focus on reducing uncontrolled air leakage to improve energy efficiency. While this can be beneficial, controlled mechanical ventilation becomes increasingly important to ensure adequate air exchange.
