Several types of air gap but most often describes the space between insulation and sheathing to allow air flow. Also between masonry and framing.
The nonconductive air space between traces, pads, conductive matter, or in any combination.
A clear vertical space between a water or drain line and the flood level of a receptacle to prevent back-flow or siphoning from the receptacle in the event of negative pressure or vacuum. Most plumbing codes require the air gap to be at least twice the diameter of the water or drain line, with a minimum of 1-1/2 inches (3.8 cm). (See vacuum breaker or back-flow presenter.)
A non-magnetic discontinuity in a ferro-magnetic circuit. For example, the space between the poles of a magnet, if filled with brass, wood, or any other non-magnetic material, is nevertheless called an air gap. Air gaps are often introduced into soft ferrite cores to prevent saturation at high DC bias currents or to simply hold a tight inductance tolerance.
a check valve used on dishwashers that prevents waste water from flowing back into the dishwasher and is usually on the countertop behind the sink
a device usually mounted at the back of your kitchen sink, that connects between your dishwasher and your
an actual physical separation between the supply pipe (faucet) and the receiving vessel (bucket, etc
a physical separation between the discharge end of a potable water supply line and the top of an open or nonpressure receptacle
a physical separation of the supply pipe by at least two pipe diameters never less than one inch) vertically above the overflow rim of the receiving vessel
a vertical, physical separation between the end of a water supply outlet and the flood-level rim of a receiving vessel
a vertical separation between a water outlet and the highest level of a potential fluid contamination source
Air gap pipes, comprise a tube within a tube with a gap between them. Used to reduce thermal inertia for faster catalyst warm up and/or to improve heat and noise insulation.
The clearance between the rotating rotor and the stationary winding on an open motor. Known as a vapor gap in a hermetically sealed compressor motor.
1. the unobstructed vertical distance between the lowest opening of a faucet which supplies a plumbing fixture (such as tank or wash bowl) and the level at which the fixture will overflow. 2. In a drainage system, the unobstructed vertical distance between the outlet of a waste pipe and the flood-level rim of the receptacle into which it discharges.
Basically the "external" distance from one pole of the magnet to the other though a non-magnetic material (usually air).
The air space between two magnetically related or electrically related parts. (i.e the space between poles of a magnet or the poles of an electric motor)
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 contamination by backflow or back siphonage.
The distance between the outlet of a faucet and the overflow level of the fixture.
Vertical, unobstructed distance, between the flood level in a plumbing fixture and the lowest water supply inlet, such as the distance between the rim of the tub and the faucet.
is a low permeability gap in the flux path of a magnetic circuit. Often air, but inclusive of other materials such as paint, aluminum, etc.
A devise mounted at the back of a kitchen sink connecting to the drain line between a dishwasher and disposer to allow the dishwasher to discharge freely into the disposer while preventing contaminated water from siphoning back into the dishwasher.
The space between magnetic poles or between rotating and stationary assemblies in a motor or generator.
A device mounted at the back of a kitchen sink that connects the drain line between a dishwasher and disposer. Allows the dishwasher to discharge freely onto the disposer while preventing contaminated water from siphoning back into the dishwasher.
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.
According to the AWWA M14 Manual - "Recommended Practice for Backflow Prevention and Cross-Connection Control", an approved air gap is the unobstructed vertical distance through free atmosphere between the lowest point of a water supply outlet and the flood level rim of the fixture or assembly into which the outlet discharges. These vertical, physical separations must be at least twice the diameter of the water supply outlet, but never less than 1 in. (25 mm). A common air gap would be that of a typical household sink in which there is a gap between the water in the sink and the faucet above it.
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 prevents the contamination of drinking water by backsiphonage or backflow because there is no way raw water or any other water can reach the drinking water.
An air space (open space) between the hose or faucet and water level, representing one way to prevent backflow of liquids into a well or water supply.
In a magnetic circuit it is the distance, in cm, of non-magnetic length introduced into the magnetic circuit. Most commonly the gap is air, but it can also be non-magnetic shims or spacers. The gap is used to introduce a magnetic resistance, () to flux lines thereby reducing the saturation effect of high levels of superimposed current onto the magnetic coil.
Air-filled space allowing contaminated water to discharge freely, preventing the contaminated water from ever siphoning back into the potable water supply.
Also called daylight clearance, air gap refers to the distance between the bottom of the hovercraft skirt and the surface beneath it.
An open vertical drop, or vertical empty space, that separates a drinking (potable) water supply from other water systems. This open gap prevents the contamination of drinking water by backsiphonage or backflow since there is no way the "other" water or any other water can reach the drinking water.
In extrusion coating, the distance from the die opening to the nip formed by the pressure roll and the chill roll.
The space between the top plate and the pole piece. This is where the voice coil sits.
The distance between the inner diameter of a V-Band clamp and the outer diameter of the associated flange. ( Click here for full definition.)
A clear vertical space between the end of the water treatment device's drainline and the flood level rim of a receptacle which holds water.
The space between the rotating (rotor) and stationary (stator) member in an electric motor.
The unobstructed vertical distance through the free atmosphere between the outlet of a water pipe and the flood level rim of the receptacle into which it is discharging.
The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture, or other device and the flood level rim of the receptacle.
An air gap, as it relates to the plumbing trade, is the unobstructed vertical space between the water outlet and the flood level of a fixture.
In Internet Protocol networking, an air gap specifically refers to a physical separation of two devices or networks. It is most recognizable in the time-honored configuration known as "sneaker-net" where the only connection between two devices or networks is via a human being providing media-switching, i.e.; floppies, CDs, USB drives, or connection/disconnection of network connections. The term derives from the fact that such networks have historically not had any physical connection to each other.
