Differential pressure is the difference in air pressure between two locations within a system.
A room with higher pressure thanits surroundings is said to have positive pressure.
A room with lower pressure than adjacent areas is said to have negative pressure.
Positive pressure areas keep particles out, while negative pressure areas prevent the escape of potentially harmful substances.
The pressure differential is maintained according to the Standard ISO classes. ISO 14644-4 recommends a pressure differentiportant in pharmaceutical environments.

A room with lower pressure than adjacent areas is said to have negative presnces.
The pressure differential is maintained according to the Standard ISO classes. ISO 14644-4 recommends a pressure differential from room to room of 5 to 20 Pascal.
According to WHO guidelines on HVAC system 10-15 of pascals.
Differential pressure is important in pharmaceutical environments.
