The procedure of entering an airlock from the external or ambient pressure environment, sealing it, equalizing the pressure, and passing through the inner door is known as locking in. Conversely, locking out involves equalizing pressure, unsealing the outer door, then exiting the lock compartment to enter the ambient environment.
The key can then be used to unlock the kiln door. While the key is removed from the switch interlock, a plunger from the interlock mechanically prevents the switch from closing. Power cannot be re-applied to the kiln until the kiln door is locked, releasing the key, and the key is then returned to the disconnecting switch interlock. [1]
'S' trap inlet to drain [further explanation needed]. The air lock phenomenon can be used in a number of useful ways. An 'S' trap (a pipe that descends from a reservoir, then curves back up, then down again) allows liquid to flow from top to bottom unhindered, and gas cannot flow through the trap unless it has enough extra pressure to overcome the liquid head of the trap.
Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.
Principal view of the pumping action of a twin-screw pump with a six-lobe female screw and a five-lobe male screw. A compressor (as opposed to a pump) would be shaped the same way, except that the shape of the lobes would change along the length of the screw, so that the volume of the trapped pockets would get squeezed smaller as they get closer to the exhaust port.

Electro-pneumatic—the motor drives an air compressor and may be located away from the door. The air pressure is used to drive the operator above the door. This type is not common, and noise can be a factor if compressor is located close to a door. Typically, the compressor can be located up to 200 feet away ensuring that noise is not a factor.
