Very generally, any moving- stream of air. It has no particular technical connotation.

A component on a compressed air line that provides wide are coverage with a thin sheet of air. Also amplifies compressed air flow, reduces noise. Used in blowing, cooling. Also known as air knife.

A component made up of a cylinder barrel, end covers, a piston rod, a steel or stainless steel piston. A device which induces action or motion with compressed air being the medium through which the power is transmitted.

A large body of air having similar horizontal temperature and moisture characteristics.

An air distribution outlet, typically located in the ceiling, which mixes conditioned air with room air.

One of the 3 possible distances:The max height from the water line to the topmost of a ship,The clearance between the topmost point and a bridge over a river,The max height from the water line to the top of the hatch coamings.

A device for drying compressed air by means of condensation obtained by over-compression or cooling, absorption, adsorption or a combination of the above methods.

The motion of air relative to a body in it.

A building energy auditing technique used to determine and/or locate air leaks in a building shell or envelope.

A component on a compressed air line that provides wide are coverage with a thin sheet of air. Also amplifies compressed air flow, reduces noise. Used in blowing, cooling. Also known as air curtain.

A crack or hole that accidentally admits a gas or lets it escape.

Device that permits passage between regions of differing air pressures, most often used for passage between atmospheric pressure and chambers in which the air is compressed. A typical modern air lock consists of a cylinder of steel plate with airtight doo ...

The mass density of a parcel of air expressed in units of mass per volume.

A small anemometer with flat vanes which indicates the number of linear feet or meters of air which have passed the instrument during its exposure.

Is a compact, low mass unit giving smooth, non-vibrating power. Several types include vane, piston, percussion and turbine type motors

A projecting aperture at the end of a tube, pipe etc. serving as an outlet for compressed air. Reduces the demand on the compressor by generating the highest thrust and volume for the lowest possible air consumption.

The presence of contaminants in the air in concentrations that prevent the normal dispersive ability of the air, and that interfere with biological processes and human economics.

The use of devices to limit or prevent the release of pollution into the atmosphere.

Indirect heat exchanger designed to transfer heat from combustion gas to the air stream added to the combustion zone.

The total gas pressure (static plus velocity).
