Replace pumps in pump module
The pumps in the Particle Monitor pump module and in the Particle Profiler pump module can easily
be replaced.
The Particle Monitor contains a sample pump: (
AQS R10
) and a purge pump (
AQS R34
). The Particle
Profiler only has a sample pump (
AQS R10
)
Typically the pumps last between 12 and 18 months. However the pumps should be replaced when
the correct flow can no longer be maintained.
Figure 6-21 The Particle Monitor contains two pumps, the Particle Profiler has one pump.
Leak check gas module
If the correct flow rate cannot be achieved through a gas module, this may indicate a leak. An
individual gas module can be checked for leaks by using a small diaphragm pump and a flow meter in
the configuration shown in Figure 6-22
