Technomed’s FA valve with humidifier bottle is a precision oxygen‑flow regulator that attaches directly to a cylinder outlet, offering accurate control of oxygen flow. The FA valve uses a flow‑meter mechanism, allowing adjustment from very low flow rates up to typical therapeutic levels, depending on the model. Attached to its outlet is a reusable humidifier bottle, which ensures that dry oxygen is moistened before being delivered to the patient, improving comfort. The bottle is designed for sterility, typically made from strong, autoclavable materials that can be cleaned between uses. This setup reduces the risk of upper airway irritation by preventing dry gas from reaching the patient. The unit includes a control knob—easy to operate even in critical situations. Safety is prioritized through built-in pressure regulation to avoid over‑delivery of gas. The streamlined design integrates both the flow‑meter and humidifier to minimize clutter and simplify bedside oxygen delivery. This FA valve system is widely used in hospital wards, ambulances, and home-care settings. It reflects Technomed’s commitment to providing safe, efficient, and user‑friendly medical gas delivery solutions.
