Installation
7.3.2 Instructions for the Pneumatic Connection
Use only screw unions with cylindrical G-threads for the compressed air and vacuum connection!
To ensure problem-free operation and a long service life of the ejector, only use adequately maintained
compressed air and consider the following requirements:
•
Use of air or neutral gas in accordance with EN 983, filtered 5 μm, oiled or unoiled.
•
Dirt particles or foreign bodies in the ejector connections, hoses or pipelines can lead to partial or
complete ejector malfunction.
1. Shorten the hoses and pipelines as much as possible.
2. Keep hose lines free of bends and crimps.
3. Only use a hose or pipe with the recommended internal diameter to connect the ejector, otherwise
use the next largest diameter.
- On the compressed air side, ensure that the internal diameter has the dimensions required for the
ejector to achieve its performance data.
- On the vacuum side, ensure that the internal diameter has the necessary dimensions for preventing
high flow resistance. If the selected internal diameter is too small, the flow restrictor and the evacu-
ation times increase and the blow off times are extended.
The following table shows the recommended line cross-sections (internal diameter):
Performance class
SCPS-L 2-07
SCPS-L 2-09
SCPS-L 2-13
SCPS-L 2-16
SCPS-L 3-16
SCPS-L 3-20

Based on a maximum hose length of 2 m.
4 For longer hose lengths, the cross-sections must also be larger.
