Metal ventilation grille with shutters
This metal ventilation grille with shutters is designed for outdoor installation as part of an exhaust ventilation system. Shutters effectively prevent air backflow, protecting interiors from outside pollutants and reducing heat loss. The grille is used in ventilation, heating, and air conditioning systems. The frame is made of high-quality metal with a polymer coating, and shutters are made of durable PVC.
