User Guide
In addition to vessel pressure, the hydrostatic pressure generated by the height difference
between vessel liquid level and pump level may assist or hamper the exhaust flow
Pump line (d) -
Located on the P-Box. The line connects the P-Box to the Diaphragm
Pump. A hydrophobic 0.2micron filter in this line provides both a sterile barrier and also
a potential barrier to the back flow of liquid from Diaphragm Pump to controller should
a diaphragm rupture.
Be sure to use the hydrophobic filter in the pump line to prevent accidental flow of liquid
from the Filtration Assembly to the P-Box.
Air Pressure regulator
- Typical range of regulator is 0
-60psi
/
4.1bar
. This is a
second
stage pressure regulator for regulating service air inlet pressure to a specified, user
required, value.
Typically, the secondary air
pressure is regulated to 35psi/2.4bar. That value is selected because that pressure is
recommended to drive the proportional pressure control valve PRV1 and it is
generally the upper limit of the pressure required to achieve set flow rates.
Air Pressure Gauge (i) -
Located on the upper side of the P-Box. Typical range of gauge is
0-60psi. It shows second stage system pressure.
Vacuum Gauge (h) -
Located on the upper side of the P-Box. Typical range of gauge is 0
to -30inHg / -0.95 bar. It shows primary vacuum pressure status.
