Hi guys,

Vacuum again ;o)

Would you like please to look to this pump specs, and let me know what you think.

FPZ SCL 15DH two stage side channel blower

0.55kW 230V single phase 50Hz electric motor

Displacement 50 m3/hr

Pressure to +30 kPa

Vacuum to -27.5 kPa


That would be close with 3.988537788 PSI......


If you already have done the vacuum table, would you use a pump like this ?
