Positive pressure definition

Positive pressure means a room or device with higher pressure than adjacent space so that air flow moves out of, rather than into, the room or device.

Positive pressure means a condition that exists when more air is supplied to a space than is exhausted, so the air pressure within that space is greater than that in surrounding areas.
