*1. Continuous operation time from the maximum suction pressure to 400Pa should be within 20minutes.
*2. Measure with a Pirani gauge (approx. 6.7 × 10
-2
Pa for MacLeod vacuum gauge).
*3. You can select a 200V or a 400V class motor. However it does not apply to different voltage motors and
the explosion-proof motors. Confirm the motor's name plate.
*4. JIS B 2290:1998 Flange for vacuum devices Appendices (for reference) Flange for maintenance
*5. Please use it in the environment of no be dewy when the temperature of cooling water is low.
*6. This value changes depending on the performance of the backing pump.
The above data is obtained when the pump is used in combination with a standard backing pump.
