The unobstructed vertical distance through free atmosphere between the outlet of the waste pipe and the flood-level rim of the receptacle into which the waste pipe is discharged.

The unobstructed vertical distance through free atmosphere between the lowest opening from any pipe or faucet that supplies water to a receptacle (sink, tank, fixture, or other device) and the flood-l [..]

In networks, air gap is a type of security where the network is secured by keeping it separate from other local networks and the Internet. While this provides security, it also limits access to the ne [..]

The "external" distance from one pole of the magnet to the other though a non-magnetic material (usually air).

In the drainage system, the unobstructed vertical opening between the lowest opening of a waste line and the flood level of the device into which it empties. Its purpose is to prevent backflow contamination.

1) The negative pressure that can result when a hand-held shower faucet or sink sprayer is dropped into a sink or tub. If negative pressure exists, wastewater can be siphoned out into the supply system. Newer products have backflow protection or a vacuum breaker (vertical spray bidet) to prevent the problem. 2) The distance between the flood level [..]

Short gap in the magnetic material forming a magnetic circuit.

The space between the rotating and stationary member in an electric motor.

In a permanent magnet alternator, the distance between the magnets and the laminates.

the physical separation that completely isolates a computer from the Internet. When absolute security of a computer or the files it contains is essential, it is disconnected from the Internet and all [..]

Short gap in the magnetic material forming a magnetic circuit.

The space between the fork cap and top of the oil inside a fork.  Used as a tuning variable to help with bottoming and harshness.

The space between magnetic poles or between rotating and stationary assemblies in a motor or generator.

"An air gap" means a visible, unobstructed and complete physical air break between the lowest level of water discharge and the level of potentially contaminated fluid downstream (critical wa [..]

serif"> - The free space that the magnetic flux must cross when a magnetic circuit contains a break. Cracks produce small air gaps on the surface of a part.

In an electrical machine, the space between the rotor and stator across which magnetic lines of flux must travel through air.

In a speaker's motor section, the space between the top plate and the pole piece. This is where the magnetic flux field is concentrated and where the voice coil interacts with it.

Open vertical gap or empty space that separates drinking water supply to be protected from another water system in a treatment plant or other location. The open gap protects the drinking water from co [..]

Open vertical gap or empty space that separates drinking water supply to be protected from another water system in a treatment plant or other location. The open gap protects the drinking water from [..]

An open vertical drop, or vertical empty space, that separates a drinking (potable) water supply to be protected from another water system in a water treatment plant or other location. This open gap p [..]

The distance between the outlet of a faucet and the overflow level of the fixture.

An air gap is a security measure implemented for computers, computer systems or networks requiring airtight security without the risk of compromise or disaster. It ensures total isolation of a given s [..]

The distance from the die lips of a polymer-melt extruder and the chill roll.

An unobstructed vertical air space that separates the end of a supply line and the flood level rim of a sink, tank, floor drain, etc. Maintaining air gaps is the best method for preventing backflow because it is simple, economical, and fail safe.

An open, vertical drop, or vertical empty space, between a drinking (potable) water supply and potentially contaminated water. This gap prevents the contamination of drinking water by backsiphonage be [..]

A clear vertical space between a water, or drain, line and the flood level of a receptacle, used to prevent backflow or siphonage from the receptacle in the event of a negative pressure or vacuum.

The space between the top plate and the pole piece. This is where the voice coil sits.

The space between magnetic poles, or between the rotating and stationary assemblies in a motor or generator.
