27. What is the function of the magnehelic gauge located on the front of my Baker BSC?

The magnehelic gauge provides a "gross" or approximate indication of HEPA filter loading, i.e., the volume of particulate matter the filter has accumulated as the cabinet operates. It provides one indication of how rapidly the filter's capacity is being diminished. This is measured by reading either motor blower suction or pressure. For example, the SterilGARD measures suction in the motor blower compartment, whereas the BioGARD samples pressure in the plenum behind the HEPA filter. - Updated: July 31, 1999
