Cleanroom Equipment Pressure:
In medical settings, a positive pressure room (protective environment) allows staff to keep vulnerable patients safe from infections and disease. In contrast, a negative pressure room uses lower air pressure to allow outside air into the segregated environment.
1. Positive Pressure.
2. Negative Pressure .
Differential Pressure Gauge : Pressure Gauge is used in Equipment’s to check the Pressure Drop across HEPA with respect to Ambient . Range -0-50 MM WC / 500 Pascal .
