A fresh air fan is designed to improve indoor air quality by bringing in clean, natural air from outside and expelling stale or polluted air. It helps maintain proper ventilation, reduces humidity, removes odors, and creates a healthier and more comfortable living environment. Fresh air fans are ideal for homes, offices, kitchens, and industrial spaces where continuous airflow is essential. With energy-efficient performance and durable design, they ensure a constant supply of fresh air while reducing the need for heavy air-conditioning or artificial cooling.
