ceiling air inlet

The frame is formed by a high-quality ABS engineering plastic model, and the sides and flaps of PVC plastic steel are anti-ultraviolet, anti-aging, and durable. The brand-new double-opening door design, two doors open at the same time, the opening state can be adjusted arbitrarily, the air volume can be adjusted freely, and the use effect is better.
