Abstract

The invention relates to a ventilation system as emergency provision at fire. Two cylinders with parallel piston rods are used. The one cylinder is designed for typical operation and can be single or double acting and is connected to a source of pressurised air. The other cylinder is sealed and acts as gas spring en is kept pre loaded by a fuse. The gas spring can be replaced by a mechanical spring.
