Their function
The AIRTEC central ejectors function according to the Venturi principle. Compressed air with 4 to 6 bar flows through a protective filter in the compressed air supply port (1.1) into the ejector creating a vacuum in the mixing chamber (C). The vacuum line is evacuated via connection (2) and another protective filter.
A check valve (D) between the mixing chamber (C) and connection (2) as well as in connection (1.2) seal off the vacuum system to the atmosphere so that in the event of the compressed air supply being interrupted in an airtight vacuum system, the vacuum remains unaffected.
To this end, the production series HV-SA with flange-mounted electronic vacuum switches has a parts control or an electronically controlled saver circuit with parts control.
With an integrated mechanical-pneumatic vacuum regulator, the production series HV-P is able to carry out an automatic saving function. Electronic vacuum switches also enable a parts control.
An air blast in connection (1.2), which also has a protective filter fitted against the infiltration of dirt, quickly relieves the vacuum and in the process, also cleans the protective filter in (2).
All ejector models can also be delivered with integrated solenoid valves, in the form of a compact unit.
A fully pneumatic ejector control system with a pneumatic vacuum switch is possible on request.
