Personal or Area Sampling

The result of extensive research and development, the PCXR4 is a constant flow air sampling pump suited for a broad range of applications. With an operating range of 1000 to 5000 ml/min (low flow applications of 5 to 500 ml/min require an optional adjustable tube holder), this battery-operated air sampling pump is ideal for industrial hygiene studies as well as environmental testing. Specifically designed for on-worker and fenceline applications, the PCXR4 air sampling pump is typically used with collecting devices such as:

  • Sorbent sample tubes and long-duration detector tubes for collecting most hazardous chemical gases and vapors from the air
  • Cyclones for collecting respirable dust
  • IOM samplers for collecting inhalable dust
  • Filters for collecting total dust, asbestos, or chemical hazards
  • Tedlar sample bags for collecting airborne chemical hazards
  • Impingers for collecting reactive chemicals into liquids

Powerful Pneumatic System

With its broad flow range, the powerful PCXR4 does the work of both a high flow and low flow pump in a single unit. Its state-of-the-art pneumatic system delivers a constant flow, resulting in accurate air volumes without the need for frequent sampler adjustments. This system includes four components:

  • Pulsation dampener for smooth airflow
  • Built-in flowmeter to monitor pump flow
  • Pressure regulator for low flow sampling
  • Filter assembly to prevent clogging of pump

Long-life NiMH Battery Pack

The NiMH battery pack provides a minimum 12-hour continuous run time. The battery charge test ensures the pump runs the entire shift.


High-accuracy Timer

Using a precision timing circuit, the PCXR4 provides an instant readout of the duration of sampling. A convenient Hold feature allows a pause in sampling; one stroke of the keypad allows the user to resume sampling.

  • Testing possible up to 12 hours
  • Timing accuracy ± 0.05%
  • Large, easy-to-read LCD

Back Pressure Compensation

The PCXR4 is factory-preset to compensate for back pressures to 40 inches water over the most commonly used flow ranges. As back pressure increases, the motor voltage automatically corrects to maintain a constant flow over the operating range. There is no sacrifice to air volume accuracy, even in dusty environments.



Multiple-tube Sampling Capability

The PCXR4s built-in constant pressure regulator allows users to take up to four simultaneous samples with rates up to 500 ml/min each using an optional adjustable tube holder (not included). Reduce time in the field and use fewer pumps with multiple-tube air sampling.


Automatic Fault Shutdown

To ensure the integrity of results, the air sampling pump is programmed to shut itself off in the event of:

  • Excessive back pressure
  • Low battery voltage

The pump will automatically enter the Hold mode, and the appropriate indicator (LoBatt or Flow Fault) will light. The LCD will show the elapsed sampling time recorded at the point of shutdown.


A High Standard of Safety

Intrinsically safe, the PCXR4 air sampling pump is UL Listed for explosive gas and dust atmospheres of Class I, Division 1 and 2, Groups A, B, C, D; Class II, Division 1 and 2, Groups E, F, G; and Class III Temperature Code T3C. ATEX-approved model is available. Contact SKC.


RFI and EMI Shielding

PCXR4 case material and unique circuitry are designed to provide shielding from radio frequency in the range of 27 to 1000 MHz. This shielding prevents fluctuations in the flow caused by electrical effects on the pump control circuitry. CE marked

A Variety of Ordering Options

The PCXR4 and its accessories can be purchased together in single and five-pack pump kits or separately for a more customized setup. Accessories include chargers (single or five station), adjustable tube holders, filter cassette holders, impinger holders, and a protective nylon carrying pouch with shoulder strap and belt. Note: Kits do not contain all the accessories listed here. Contact your SKC regional sales representative for complete ordering information. CE marked
