AIR LIQUIDE Selectaflo HP Preci Gas flowmeter, pressure regulator Brand NEW FEATURES: Flowmeter-pressure regulator combination designed to be mounted directly on high-pressure medical gas cylinders (e.g., oxygen) to deliver a controlled flowrate to the patient regardless of upstream cylinder pressure. Key Features of Selectaflo HP Integrated pressure regulation and flow control in one device – simplifies installation and handling. Ergonomic, easy-to-use design with comfortable grip and intuitive adjustment. Accurate and reliable flowrates , even if cylinder pressure varies. Durable construction : robust ABS/polyamide housing, resistant to shock and UV rays. Simple maintenance , smooth surfaces and rounded shape for easy cleaning. High safety level : parts carefully selected, design based on long experience in high-pressure medical devices. Role of Preci The Preci component is the pressure-reducing regulator that ensures stable, safe downstream pressure from a high-pressure cylinder. It works together with the Selectaflo to provide smooth, controlled gas delivery suited for medical therapy applications like oxygen therapy. How it Works Mounted on the cylinder valve, the Preci regulator first reduces cylinder pressure to a usable level. The Selectaflo HP then controls the flowrate (often in calibrated steps) delivered to the patient or system. Benefits in Use Combines pressure reduction and flow control in one unit — simplified setup. Ergonomic and intuitive for healthcare professionals. Robust and low-maintenance , suited to frequent clinical use.
