The Dräger Automatic Switch over Valve (PAS® ASV) enables the user to connect compressed air breathing apparatus to an external air supply, such as a factory ring main, and be safe in the knowledge that if the external supply were to fail, there would be a safe and uninterrupted transition to the wearer’s back-up air supply.
The PARAT® filtering escape hoods were developed with users, placing the focus on the fastest possible escape. Optimized operation and wearing comfort, a robust case and a sealed filter ensure protection from toxic industrial and/or fire-related gases, vapours and particles for at least 15 minutes.
