Notes:
- When additional air flow pressure is set to 0.2MPa and supply pressure to the dust collector to
0.4MPa.
- Discharge time is the time required to reduce electricity on the static plate (150 mm x 150 mm, static
capacity 20 pF) from 1000 V to 100 V.
- The above shown values are measured using SMC's measurement instruments and conditions, and not
the guaranteed values.
