T-piece and Tubing

T tubing
The T-piece is used for pump-based detectors where users need to detect a positive pressure stream from a gas source (i.e. gas bottle). Pressure seen by the detector micro-pump should remain as constant as possible. Comes with a particle filter.
???? How does it work? The setup works in two basic ways: 1) Gas source airflow exceeds the flow supplied by the micro-pump. In this case, the excess air will be exhausted out from the particle filter. 2) Gas source air flow does not meet the micro-pump volume demand. In this case, the micro-pump needs "make up" air volume, which will be supplied from the surroundings. The ambient air will be directed through the particle filter and into the micro-pump. In this case, the incoming airflow will dilute the gas source concentrations.
