Compressed Air powered suction units generate the vacuum with the compressed gas, usually air or oxygen. For the conversion of compressed air into vacuum, an ejector (Venturi device) is used. This eliminates the need of a separate installation of a vacuum pipeline. The Venturi suction unit can be connected to the central system of the compressed gas or to a cylinder. A knob for fine or rough vacuum regulation, a manometer (from 0 to -0.7 bar) for the display of currently selected vacuum power, a silencer and a bacterial filter are installed on the device. Some of the advantages of medical venturi ejector units:

1. Precise Gas Delivery: Medical venturi ejector units provide a precise and controlled delivery of medical gases to patients, ensuring that the correct concentration of gas is delivered for optimal patient care.
2. Cost-Effective: Medical venturi ejector units are a cost-effective way to deliver medical gases to patients, as they require no electricity or moving parts and are easy to maintain.
3. Safety: Medical venturi ejector units are designed to meet strict safety standards, ensuring that the gases delivered to patients are free of contaminants and at a safe pressure.
4. Flexibility: Medical venturi ejector units can be used with a variety of medical gases and are suitable for use in a wide range of medical applications, from critical care to home oxygen therapy.
5. Quiet Operation: Medical venturi ejector units operate quietly, making them ideal for use in hospital wards and other settings where noise levels need to be kept low.
6. Energy Efficient: Medical venturi ejector units require no electricity or moving parts, making them an energy-efficient and eco-friendly option for delivering medical gases to patients.

Overall, medical venturi ejector units provide a safe, precise, cost-effective, and flexible solution for delivering medical gases to patients in hospitals and other medical facilities.
