Selecting an Air Source
The Geocontrol PRO is an easy-to-use portable compressor and logic unit specifically
designed to operate Portable Bladder
Pumps deployed down to 180’ (55 m) or less.
Air consumption depends on the volume of tubing and the size of deployed Bladder Pump.
Follow the general guidelines and examples below to calculate the air consumption for
specific sampling configurations.

Calculation guideline :
Volume of Tubing (in³/cm³)
+ Volume of Bladder Pump (in³/ cm³)
= Air Consumption per cycle (in³/ cm³)
If planning to use an air compressor, use one with a reserve tank to ensure proper air
supply to the pump. If using a Nitrogen Tank, see Figure 3-1 for Nitrogen Tank Volume vs.
Bladder Pump consumption. Ensure the air compressor is constructed from suitable
materials for sampling PFAS compounds.
