The PRU 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.
