Dräger PAS® ASV: The Seamless Automatic Switchover Valve

Ensure uninterrupted breathing air with the Dräger PAS® ASV, an Automatic Switchover Valve that provides a critical layer of safety for professionals. Designed to seamlessly connect a compressed air breathing apparatus to an external air supply, this device automatically switches to the wearer’s backup cylinder if the external source fails, all while maintaining positive pressure in the facemask.

✨ Product Features

• Automatic & Uninterrupted Air Supply: The PAS® ASV automatically transitions from an external air supply (like a factory ring main) to the wearer’s SCBA cylinder if the primary supply fails. This process is seamless and maintains positive pressure in the facemask at all times.
• Compact & Lightweight Design: With its low-profile and light construction, this valve is easy to use in confined spaces and won’t add unnecessary bulk to the SCBA system.
• Integrated Warning Device: A built-in warning device alerts the user with a distinct audible signal (over 90 dBA) when they are breathing from the backup cylinder, prompting them to exit the hazardous area.
• Robust & Reliable: The device is engineered to operate in a wide temperature range and is approved for use with Compressed Air Breathing Apparatus certified to EN137 and EN402 standards.
• Versatile Compatibility: The PAS® ASV is an ideal accessory for various Dräger SCBA systems, including the Dräger PAS® Lite, and can be easily integrated with a range of breathing apparatus and chemical protection suits.
