Working Principle

The FCS ceiling curtain operates using a tubular motor, which drives the fabric to open and close through a continuous wire loop movement, achieving sun shading. The Eifoo FCS ceiling curtain mechanism is divided into two parts: transmission and fabric. The other end of the upper transmission part is the power end, which uses the tubular motor's rotation to drive the reel and the reel rope mechanism attached to it, allowing a wire rope to be wound or unwound. The other end of the transmission part is a fixed spring pulley, through which the wire changes direction, allowing both ends of the wire to be fixed simultaneously on the reel mechanism, and to maintain tension with the wire. The upper part of the fabric section is a wire that is fixed at both ends and kept taut (a sliding door track is used instead if the ceiling curtain span is too large). The lower part is the fabric itself. The fabric is installed starting from the top with a guide roll, evenly spaced (usually around 1m). Rolling pulleys are mounted on the guide roll, which rolls on a fixed wire. The first guide roll is connected to the transmission wire, allowing the fabric to be opened or closed along the fixed wire as the motor drives it.

Knowledge for practical application
1. The FCS system is compatible with domestic motor series and the French SOMY series of tubular winding machines.
2. Utilizes wire rope transmission, low noise level, mainly used for large-area folding roofs.
3. The largest area can reach up to 35 square meters. When the width exceeds 3.5 meters, it can be made in a two-to-one or three-to-one configuration.
