Simple to Operate
With its broad flow range (5 to 5000 ml/min), 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 you can get accurate air volumes without the need for frequent sampler adjustments. This system includes:
Pulsation dampener for smooth air flow
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 44XR air sampling pump is a constant flow sample pump suited for a broad range of applications. With an operating range of 5 to 5000 ml/min (low flow applications of 5 to 500 ml/min require a 224-26 series Adjustable Low Flow Holder), this battery-operated pump is ideal for industrial hygiene studies as well as environmental testing. Specifically designed for ''on-worker'' and ''fenceline'' applications, the 44XR 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.
Back Pressure Compensation
The 44XR air sampling pump is factory-preset to compensate for back pressures to 40 inches water (over the most-used flow ranges). As back pressure increases, the motor voltage is automatically corrected to maintain a constant flow over the operating range. You will not sacrifice air volume accuracy, even in dusty environments.
Lightweight and Durable
Weighing only 34 ounces, the 44XR air sampling pump is ideally suited to personal sampling. An anti-tamper cover and durable construction allow the pump to withstand the rigors of ''on-worker'' use, time and time again. Rechargeable NiCad 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
SKC's 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.
A High Standard of Safety
Intrinsically safe, the 44XR air sampling pump is UL listed for explosive gas and dust atmospheres of Class I, Groups A, B, C, D: Class II Groups E, F, G; and Class III for Temperature Code T3C.
The Indispensable Air Sampling Pump
Highly accurate yet easy to operate, the versatile 44XR air sampling pump 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:
Sorbent Sample Tubes
Sample bags
Long-duration detector tubes
Impingers
Filters
Cyclones
Ordering Information
Multiple Tube Sampling Capability
The 44XR air sampling pump's built-in constant pressure regulator allows you to take up to four simultaneous air samples with flow rates of up to 500 ml/min each using an optional 224-26 series Adjustable Low Flow Holder (not included). With multiple tube sampling, you'll reduce time in the field and use fewer pumps.
Long-life NiCad Battery Pack
The NiCad battery pack provides a minimum 8-hour continuous run time. The battery charge test ensures the pump runs the entire shift.
A Variety of Ordering Options
The 44XR air sampling pump 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 protective nylon carrying pouch with shoulder strap and belt. Note: Kits do not contain all of the accessories listed here. Contact your SKC regional sales representative for complete ordering information.
