RWA access covers (German short for fire protection and smoke extraction) have all required fire protection components. RWA helps to save lives in case of an emergency. They enable a fast extraction or backflow of smoke thanks to the easy opening with gas struts. The access covers will be opened with a special key from the fire departement. It is also possible to receive the cover for a fire ventilator with a hose adapter. The RWA access covers can be produced with a hydraulic system or a manual handling to ensure an excellent heat-extractor.
