A faucet aerator (or faucet aerator) is often found at the tip of a modern indoor water faucet. Aerators can be easily screwed into the faucet head, creating non-splashing streams and often providing a mixture of water and air.

Function
An aerator can
- Prevents splashes
- The shape of the flow of water coming out of the spout of the faucet, to produce a straight flow and evenly suppressed
- Save water and reduce energy costs
- Reduce the tap noise
- Increase the perceived water pressure (often used in homes with low water pressure); sometimes described as pressure regulator or flow regulator
Prevent splash
When a stream of water touches the surface of the water must go to a place, and because the flow is uniform, the water will tend to flow in the same direction. If a single stream touches a curved surface, the flow will be in shape and easily flowed with the volume of falling water. Adding an aerator does two things; reducing the volume of falling water that reduces splash distance, and creates multiple "mini-streams" in the main stream. Each mini-stream, if it falls by itself, will splash or flow in a unique and different way when it hits the surface, compared to other mini-streams. Because they all fall at the same time, the flow will flow in their own way but eventually reach other splash streams. The resulting interference cancels out most of the spark effect.
Conservation and energy reduction
Since the aerator limits the flow of water through the faucet, water use is reduced compared to the same time of flow without the aerator. In the case of hot water, because less water is used, less heat energy is used.
The perceived water pressure
The perception of water pressure is actually the speed of water when it touches the surface, (hands, in case of hand washing). When the aerator is added to the faucet (or fluid flow), there is a high pressure area created behind the aerator. Because of the higher pressure behind the aerator and the lower pressure in front of it (outside the faucet), because Bernoulli Principle there is an increase in fluid flow velocity.

Process
Aeration occurs in two basic steps:
- The air is drawn into the water stream, breaking the stream into a stream of tiny droplets mixed with air.
- The mixture of air and water passes through the screen, further mixing air and water and evenly distributing the resulting stream.
Design and features
The three main components of the aerator are: housing, inserts and rubber washers.
The faucet air conditioner may be classified by the flow rate and type of water flow (aeration, non-aeration, spray) it produces. In general, standard sized aerators are available with women (M22x1) or male threading (M24x1). Bathtub spouts often have a larger diameter with male M28x1 threads. The United States uses different thread sizes: 15/16 "-27 for standard-sized and 55/64" -27 men for standard-size female threads.
Using a faucet aerator can help meet local regulations and construction standards such as ASME A112.18.1, US Leadership in Energy Certification and Environmental Design (LEED) or WELS (Australia/New Zealand). In Europe, the EN246 European standard "Sanitary tapware - A common specification for flow rate regulators" defines flow rates and noise reduction requirements.
