Their function
production series HV-P isable to carry out an automatic saving function.
Electronic vacuum switches also enable a parts
control.An air
blast in connection (1.2), which also hasa 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 withintegrated
industrial solenoid valves, in the form of a com-
pact unit.A fully pneumatic ejector control system with apneumatic vacuum switch is possible on
request. The AIRTEC central ejectors function accordingto 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 ejec-
tor creating a vacuum in the mixing chamber
(C). The vacuum line is evacuated via connec-
tion (2) and another protective filter.A
check valve manufacturer (D) between the mixing chamber(C) and connection (2) as well as in connection
(1.2) seal off the
vacuum system to the atmos-
phere 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 With an integrated mechanical-pneumatic vacu-
um regulator, the >
