Faucet aerator

An aerator (English aerator, aerator or even mixing nozzle ) is a nozzle that is often attached to the spout of a faucet. He is largely responsible for the observable properties of the water jet and evaluates the beam on. Due to physical and psychological effects it reduces when washing your hands to water and energy consumption.

Application

The task of aerators is the shaping of the water jet on sanitary fittings. Under different circumstances at the operation (different water pressures), he tries to ensure the best possible beam, a soft, rippling stream. Characterized and the syringes will be prevented. The main purpose is to reduce the water flow. This results in a savings. The sensed current power increases, the perceived temperature is higher in cold water and the light rushing noise gives the beam also psychologically a stronger effect. When washing your hands can thus be saved and be the temperature of the water low water. The potential reduction works so (for example): a few fractions of a second, the water When the end of washing hands without motion goes according to you has turned off the tap completely. Without aerator would run from the tap at this time more water than with luftversetztem water. Every year, these are several hundred liters of savings at 5 times daily hand washing.

Aerator can in their characteristics have various objectives, such as Fittings sounds low to keep (some models) or local standards, comply with regulations and laws. There aerator with aerated jet, laminar jet and jet shower. Aerator is available in different flow classes, including a special water-saving models (eg, 7 l / min ), usually at 3 bar flow 15 liters per minute ( flow class A). A further development of the jet regulator is the water flow regulator.

The importance of the flow regulator was clarified in 2010 when two employees of the company Neoperl were nominated for the European Inventor Award for its further development.

Structure and variants

An aerator consists of a mouth piece, an inner part and a seal. The inserts are made ​​of either plastic or metal. Plastic components calcify generally slightly slower than devices with comparable metallic surface and can be designed more freely in the manufacture, so that the flow can be easily optimized. The advantage of the metal inserts is the higher robustness of the material so that they are not damaged in case of gross mechanical cleaning.

There aerator with internal thread ( screw-, 22 mm metric thread, trade name IG M22 ) and external thread ( for threading, 24 x 1 mm metric fine thread, trade name AG M24 ). Badewannenausläufe usually have aerator with more diameter ( outside thread 28 mm, trade name AG M28 ). In addition, there are the sizes M18, M19 and M21, which are too often get only on demand from distributors.

Aerator with 1.2 l / min flow rate

Water -saving model

A particularly economical model shows the following data: Consumption: an average of 1.2 l / min ( a high-quality air mixer shower when she starts to mix air, consumes at least 3 l / min) Drop size: 0.3 to 2 mm Details: For increasing the water pressure, the angle of the microdroplets widened. Despite the drop, it feels more like a water jet. Use: ideal for washing and hand washing, but for filling vessels only partially
