Breath Actuation Controller Model BAC 2100

A cut-down version of the Critical Flow Controller Model TPK 2100, the Breath Actuation Controller Model BAC 2100 is an electrically operated, timer controlled two-way solenoid valve.

The BAC 2100 is a microprocessor-controlled instrument specifically designed for use in three test applications:

  1. Conventional Metered Dose Inhalers (MDIs) when testing to USP specifications
  2. Breath Actuated (or Breath Operated) Metered Dose Inhalers
  3. Spacers and Valved Holding Chambers (VHCs) used with MDIs

In practice, it is positioned in the line between the DUSA collection tube/cascade impactor and the vacuum pump in order to control the air flow supply to the inhaler under test.

The solenoid valve employed provides near instantaneous starting and stopping of the air flow during testing and has both delay and inhaled time functions.

Two versions are available, the BAC 2100 and BAC 2100-R.
