Function
AIRTEC Classic ejectors work according to the Venturi principle. Air compressed between 4 and 6 bar, which is as dirt and oil free as possible, flows through the Venturi nozzle (B) via the compressed air supply (A); this is protected against large particles of dirt by a protective filter.
As a result of the flow cross-section in the nozzle being narrowed considerably, the flow velocity increases to the supersonic level.
In the mixing chamber (C), the quick-moving air jet hits the atmospheric air of the vacuum line (D) and whisks this along into the up-take nozzle (E), also known as a diffuser.
In this process, the required negative pressure is creating vacuum. A protective filter in the vacuum connection (D) prevents large particles of dirt getting into the vacuum area, thus preventing malfunctions in the mixing chamber (C), which can lead to the vacuum failing to be generated.
The granular silencer in the exhaust air outlet (F) reduces the noise of the exhaust air flow and allows the fine dirt from the vacuum area to pass without resistance. With the protective filters in (A) and (D) a longer service cycle is achieved.
By installing a blow off valve in the exhaust air outlet (F), the vacuum can be dispelled very quickly. It frees the work piece from the suction cup or ventilates the container and simultaneously blows the dirt from the protective filter.
