A standard dew point that is expected by a regenerative dryer is −40 °C (−40 °F); this means that when the air leaves the dryer there is as much water in the air as if the air had been "cooled" to −40 °C (−40 °F). Required dew point is dependent on application and −70 °C (-94 °F) is required in some applications.
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
Purge or "sweep" air is thus expanded (to atmospheric pressure) and subsequently vented to the atmosphere. The "dryer" purge air which is carried or swept along the outside of the hollow bundle of fibers creates a vapor pressure gradient between the "wet" compressed air on the inside the fibers and the "dryer" sweep air on the outside the bundle.
In some applications, air and water streams are simultaneously pushed upwards through the granular media followed by a rinse water wash. [3]: 213–4 Backwashing continues for a fixed time, or until the turbidity of the backwash water is below an established value. At the end of the backwash cycle, the upward flow of water is terminated and the ...

The impact tube pressure is connected to "Chamber B" on the side of the air metering diaphragm farthest from the carburetor body. As the air pressure in chamber B is increased, the diaphragm is moved toward the carburetor body. [14] The difference in pressure between chambers A and B creates what is known as the air metering force'. [14]
