AV Venturi suction units

The Venturi AV/500 and AV/1000 vacuum generating system units are particularly suitable in all hospital applications in which it is necessary to get values of vacuum up to -850 mbar and where a central facility of vacuum generation for suction is missing, often for technical choice.

As it is well known, the physical principle called “Venturi” allows to get depression from a fluid under pressure, which is obtained, in case of these devices, using medical compressed air coming from the centralized distribution plant. Such devices are composed essentially of a brass chrome-plated body, a needle valve with vacuum adjustment knob and a vacuum gauge. The version AV/1000 fits also a quick I/0 button switch and a large gauge, while in the version AV/500 a protective silicone cover on vacuum gauge avoids damages caused by possible impacts during transport or use.
The AV/500 and AV/1000 Venturi vacuum generating system units are manufactured with outlet threaded connection for screwing in the usual collection containers for suctioned fluids, or for direct connection to the EasySAFE®PLUS safety jar, through a specific quick release integrated connection.
