Compatible with both the Ultraflow™ analgesic and oxygen demand valves, this single use AGSS exhalation valve with adult face mask (not included) enables high flows of Entonox or Oxygen with very low inspiratory effort.

Designed for self-administration of medical gas, it incorporates an ultralow resistance one-way valve and viral filter, directing exhaled gas away from the Ultraflow™ handset to an AGSS (Active Gas Scavenging System) and other closed systems such as the Nitrous Oxide Cracking Technology.

Lifespan – 30 days after use by single patient, otherwise single patient use.
