Acoustic noise test data ***
* The ambient air temperature must be less than 30℃.
** The gas ballast flow rate is set by a built-in orifice. (at atmosphere pressure)
When the gas ballast is supplied with high pressure, please set the supply pressure
(0.05MPa(Gage pressure) or less) and set the gas ballast flow rate to 8.4Pam3/s.
The pumping speed and the ultimate pressure might be effected by the gas ballast frow rate.
Install valve, check valve, and filter to the ballast port if necessary.
The ability for moisture exhaust in the gas ballast is 10g/hr at the maximum.
*** Measured on the following condision
(1) Pump is operating under ultimate pressure. (no gas ballast)
(2) Measured at 1m distance from cover.
