Pressure airflow

Pro-Tech manufactures the PTAF 2 and PTAF Lite pressure-based sensors, which generate accurate signals of respiratory airflow. Both generate an accurate flow-based snore channel. The PTAF2 can be used in either AC or DC configurations and during nCPAP titrations. The PTAF Lite is an AC only device most often used during diagnostic studies.

  • Discrete airflow and snore signals
  • Gain Control
  • AC and DC Compatible
  • Differential pressure ports (PTAF2 only)
