And the ABS plastic clamp stand between blades can be used. The fixed filters can be drawn along the track when washing. After washing, can put into along the track to use continuously.

    Fixed bar type air opening can be fitted on the sidewall or on the ceiling in heat/cold supply air conditioning system.

    Natural-hung shutter can escape air automatically in the positive pressure room. Generally, depending on the shutter’s own weight hangs naturally to separate the air exchange. When the indoor air pressure is bigger than that of the outdoor, air current will blow the shutter opening and go out of the room. On the contrary, when the indoor air pressure is smaller than that of the outdoor, air current can’t come into the room. So this shutter has one-way function.

     Diffuser is an ordinary air intake opening.

    The twist outlet sends out swivel jet, and has many characteristics such as big induction ratio and quick air deceleration. It may be used for air supply of large air flow and large temperature difference to reduce the quantity of tuyeres. It may be mounted on ceiling, supplies air for either the less than 3m short space or the middle height and large area, the height may be above 10m.
