FSS ceiling curtain system mainly consists of tubular motor and elastic tension system. One end is the drive shaft, which is equipped with tubular motor; the other end is the driven shaft, which is equipped with spring mechanism. The positive rotation of the motor drives the fabric forward. The spring at the other end tightens gradually, stretches the fabric, loosens the reverse spring of the motor, and rolls back the sunshade fabric. Its operation is simple, the motor works with little noise and runs smoothly.
