※
1. Secure supply pressure as listed when the vacuum generator is in operation. (Take pressure drop into account.)
※
2. The values in the table are reference values only. Suction flow varies according to the vacuum system conditions; vacuum
port dia. or tube length.
※
3. The values in the dark highlight show the characteristics at the rated supply pressure.
