Round Air Vent Grille 150 mm Stainless Steel with Metal Mesh

70 80 mm 100 mm 150 mm ventilation grills currently offer 4 sizes of ventilation grilles. When buying, please carefully measure the inner diameter of the hose and choose the ventilation grille that suits you best. Ideal for indoor and outdoor heating of homes, air circulation and other problems. Duplex Air Vent Cover has a flap cover tilted at about 45º to prevent rainwater from entering the pipe. Inside there is also a wire guard that prevents birds or other unwanted flying insects from entering. This allows for more ventilated and cooler air circulation in the room. Compared with PVC grills, which become brittle under UV rays, stainless steel ventilation grilles are more durable because they are windproof, rain and sunshine, not easy to deform and fade. You can adjust the side clips directly, then slide the grid into the pipe to fix it, or nail it to further strengthen it. The supplied nail-free glue can fill gaps, while steel hose clamps can better secure softer tubes like aluminum foil tubes. Please note that the ventilation grille is stamped and the edges are sharp. So please wear gloves during installation to avoid cuts. We always focus on the user experience. If you have any questions or suggestions, please feel free to contact us.
