This PVC register is used for outside air intake openings, indoor air exhaust openings, or indoor air supply openings.

How to Use

The intake register produces little noise and allows reliable air volume adjustment. For operation, see the section below.

2. For the indoor air exhaust register, install it near a window with a structure that prevents rainwater from entering. Install insect-proof mesh on the back side of the indoor air exhaust grille. The exhaust register produces little noise and allows reliable air volume adjustment. For operation, see the section below.

3. The indoor air supply register has a neat appearance, does not generate noise, and provides reliable air supply performance. The shutter provided on the back side has a sturdy structure, does not cause vibration or noise, and allows reliable air volume adjustment.

Operation Function
1. The front grille can be manually adjusted to freely change the airflow direction up, down, left, and right. Move it with your fingertips to the desired direction.

2. The shutter can be opened and closed by turning the screw on the shutter operation section with a flathead screwdriver. For air volume adjustment, check the indicator plate (S - O). Turning the screwdriver toward S closes the shutter, and turning it toward O opens the shutter. Adjust the air volume using the method described above.
