Sample Draw Pump Unit

Connects to a gas detector and draws samples of air into the gas detector from hard to access locations such as shafts, tall ceilings, wells, pits, small rooms, etc.

Uses a pump to pull sample air through a length of tube into the gas detector, across the sensor and exhaust it from the outlet port

  • Sample draw pump and adjustable flow meter
  • Compatible with many types of gas detectors
  • Standard water / dust tight, corrosion resistant enclosure (drip proof)

Description

The PRU-24 is a self-contained Sample Draw Pump Unit that can be utilized with most gas detectors. It contains a pump that is designed to draw samples of air from hard to access locations such as shafts, tall ceilings, wells, pits, small rooms and other locations where it is difficult to install gas detectors. The sample draw pump pulls air from the sampling area through tubing connected to the inlet port, over the sensor and exhausts it from the outlet port. If the gas readings are higher than a specified set point, the gas detector will go into alarm.

The unit can be purchased with 24 VAC or 24 VDC operating power and includes a sample pump, adjustable flow meter, in-line particulate filter with a water tight, polycarbonate enclosure.

The tubing and flow adapter that fits CETCI gas detectors are sold separately.

Caution: The Sample Draw Pump Unit should not be used inside classified hazardous areas or to sample draw combustible gases exceeding 50% LEL concentrations or Oxygen concentrations above 30% vol because the pump is not intrinsically safe.
