Prestan Professional's Rescue Mask adapters are for use when training with pocket masks.
Use these affordable, disposable adapters in place of expensive filter and valves for cost-effective training.
The valve features an integral air filter that obstructs the flow of contaminants and they fit all standard rescue masks (15mm I.D. or 22mm O.D.).
