Foam Flow Aerator advantages and Functions : An aerator serves the following purposes: 1. Prevent splashing 2. Shaping the water stream coming out of the faucet spout, to produce a straight and evenly pressured stream. 3. Water conservation and reduction in energy costs Reducing faucet noise 4. To increase the perceived water pressure, (often used in homes with low water pressure) Prevents splashing: When a single stream of water hits a surface the water must go somewhere, and because the stream is uniform the water will tend to go mostly in the same direction. If a single stream hits a surface which is curved, then the stream will conform to the shape and be easily redirected with the force of the volume of water falling. Adding the aerator does two things; reduces the volume of falling water which reduces the splash distance, and creates multiple “mini-streams” within the main stream. Each mini-stream, if it were falling by itself would splash or flow in a unique and different way when it hit the surface, as compared to the other mini-streams. Because they are all falling at the same time, the streams will splash in their own way but end up hitting other splash streams. The resulting interference cancels out the majority of the splashing effect. 2. Conservation and energy reduction: Because the aerator limits the water flow through the faucet, water use is reduced as compared to the same time of flow without an aerator. In the case of hot water, because less water is used, less heat energy is used. 3. Perceived water pressure: The perception of water pressure is actually the speed of the water as it hits a surface, (the hands, in the case of hand washing). When an aerator is added to the faucet (or fluid stream), there is a region of high pressure created behind the aerator. Because of the higher pressure behind the aerator and the low pressure in front of it (outside the faucet), due to Bernoulli’s Principle there is an increase in velocity of the fluid flow.
