Vac-U-Go Sampler

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 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 Sample Pump.

Note: Sonic flow is attained when a vacuum pump pulls air through an orifice to 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.
