VAC-U-GO Sampler
For Flows up to 30 L/min and Sonic Flow Applications
The Vac-U-Go non-compensating vacuum pump is a rotary vane-type pump that provides
flows
up
to
30
L/min
and
maintains sonic flow when used with the SKC
BioSampler ®. The
AC-powered
Vac-U-Go
features
a protective housing with handle and can be used for a variety of ambient and
indoor air sampling applications including asbestos, bioaerosol, stack, VOC,
and
fenceline monitoring. It is ideal for sampling bioaerosols using the
BioSampler ® or the AGI-30 Impinger. The SKC BioSampler does not require
a critical orifice accessory for sonic flow.
The line operated Vac-U-Go Sampling pump has a permanently lubricated
motor that is mounted in a housing with a vacuum pressure gauge
to indicate sonic flow. and a throttling valve to adjust flow. Both
models are supplied with an extension rod for mounting media and
a power cord.
The Vac-U-Go Sampler can be operated in two different modes: non-compensating
and BioSampler. Vac-U-Go is a non-compensating, therefore, it is
not suitable for compliance sampling in non-sonic mode. For indoor air
studies, compliance, or other applications that require a quiet,
compensating vacuum pump, use the QuickTake 30 or Quicktake 15 Sample
Pump.
Note: Sonic flow is attained when a vacuum pump pulls
air through an orifice create a condition where the downstream pressure
is 52% of the upstream
pressure. At this point, air velocity through the orifice has reached
the speed of sound and cannot increase, therefore the orifice becomes
"critical." The fixed air velocity at the critical orifice also
limits the airflow so that the condition remains constant regardless
of pressure variations in the system. Airflow will remain constant
at vacuum levels >15 inches Hg.
