Air/gas sampling apparatus for compressed air/gas sources

An air/gas sampling apparatus to retrieve, store, and ship an air/gas sample from a high-pressure air/gas source comprising:

• a filter housing including:
• a filter housing inlet segment including an inlet orifice and defining a flow restrictor passage,
• a filter housing outlet segment including a central outlet passage and removably connected to the filter housing inlet segment, the filter housing inlet segment and the filter housing outlet segment defining a filter chamber at a flow restrictor passage outlet, the filter chamber having a chamber inlet and a chamber outlet, and
• a filter pad disposed in the filter chamber, whereby the entirety of the air/gas sample flows into the flow restrictor passage and through the filter pad to ensure the quality of the test of the air sample, the flow restrictor passage reducing the air/gas sample flow to the filter chamber;
• and
• a sample bag for receiving and storing the air/gas sample from the chamber outlet, the sample bag including an inlet fitting within an internal check valve, the inlet fitting in fluid communication with the filter housing.
