Simple to Operate

With its broad flow range, the powerful 44XR air sampling pump does the work of both a high flow and a low flow pump in a single pump unit. Designed for rugged environments and repeated use, its state-of-the-art pneumatic system delivers a constant flow, so users can get accurate air volumes without the need for frequent sampler adjustments. This system includes:
  • Pulsation dampener for smooth airflow
  • Built-in flowmeter to monitor pump flow
  • Pressure regulator for low flow sampling
  • Filter assembly to prevent clogging of the pump

All SKC XR Series Universal Air Sampling Pumps are equipped with a stainless steel belt clip, built-in accessory mount for impinger brackets, anti-tamper control cover, and external exhaust port for bag sampling applications. For easy repair, replacement parts are available in preassembled modules.

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 low flow 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
The 44XR air sampling pump is so dependable, we guarantee its performance for a period of one year from date of purchase.

Ordering Information

Back Pressure Compensation

The 44XR 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.

Lightweight and Durable

Weighing only 34 ounces, the 44XR is suited ideally to personal sampling. A tamper-resistant cover and durable construction allow the pump to withstand the rigors of on-worker use time and time again. Rechargeable batteries provide a reliable power source that can be restored overnight. The 44XR is a workhorse air sampling pump, designed for rugged, repeated use.

RFI and EMI Shielding

44XR 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's control circuitry. CE marked.

A High Standard of Safety

Intrinsically safe, the 44XR 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.

The Indispensable Air Sampling Pump

Highly accurate yet easy to operate, the versatile 44XR is suited for industrial hygiene studies as well as environmental testing. Specifically designed for on-worker or personal applications, this sampler is typically used for TWA, STEL, or Ceiling sampling using a wide range of sampling media including: Ordering Information

Multiple-tube Sampling Capability

The 44XR 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 low flow holder (not included). Reduce time in the field and use fewer pumps with multiple-tube air sampling.

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.

 

A Variety of Ordering Options

The 44XR 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 low flow 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.
