Sampling Pump
Catalog No. 228-9605 and 228-9605B
The Vac-U-Go non-compensating vacuum pump is a rotary vane-type pump
that provides fl ows up to 30 L/min and maintains sonic fl ow when used with the
BioSampler
of ambient and indoor air sampling applications including asbestos, bioaerosol,
stack, VOC, and fenceline monitoring. It is ideal for sampling bioaerosols using
the SKC BioSampler or the AGI-30 Impinger.
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 fl ow
and a thro ling valve to adjust fl ow. Both models are supplied with an extension
rod for mounting media and a power cord.

Cautions
• Pump only clean, dry air.
• Protect pump from dirt and moisture.
• Pump is not intended for use outdoors.
• Protect surrounding items from pump exhaust air.
• Use only a three-wire grounded cable.
• Pump produces a high-pitched whine when operated.
• Do not pump fl ammable or explosive gases.
• Do not operate pump in hazardous locations; not UL Listed for intrinsic safety
Operation
The Vac-U-Go Sampler can be operated in two diff erent modes: non-compensating
and BioSampler. Vac-U-Go is 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.
Non-compensating Mode
1. Use fl exible tubing to connect the outlet of a
representative sample medium to the pump
inlet.
2. Connect a rotameter or calibrator to the
sample medium inlet.
3. Using the provided power cable, plug the
pump into a wall outlet and press the pump
power switch to the “on” position.
4. Use the valve adjust to set the desired fl ow
rate (see rotameter/calibrator operating instructions).
5. Remove rotameter or calibrator and replace representative sample medium with a
new unexposed medium.
6. Sample for the desired sampling period.
7. Turn off pump and unplug from wall outlet.
8. Package sample appropriately for shipment to a laboratory.

3. Use the valve adjust to open the
valve fully. The pressure gauge
should indicate > 15 inches Hg vacuum.

Note: The BioSampler features built-in critical orifi ces. No other orifi ce is needed to achieve
sonic fl ow.
