The SI 163VSD Roll-Fast Doors are produced for internal openings up to 4500mm high by 4000mm wide, and are capable of being installed in areas with an air-pressure differential of no more than 15 pascals.
All doors are fitted with a durable vinyl panel with a clear PVC centre section, 1000mm high by the full width of the door opening enabling vision through the door.
Emergency access is available via a hand chain.
The standard operational speed of the SI 163VSD Roll-Fast Door is 1200mm - 1500mm per second (with speed variator
mounted to motor/gearbox).
A photoelectric cell is installed within the doorposts to prevent the door from closing, should the cell be obstructed.
ACTIVE REVERSING EDGE:
Within the bottom rail, a self-guarding safety edge system is fitted. When triggered, this system will return the door to the open position and “lock” the door in the open position until reset.
