Faucet Aerators for Manufacturers: Best Stream Performance, Water Conservation & Flow Regulation

Faucet aerators – small parts, large effect

They are integrated into the spouts of washbasin, kitchen and bathtub faucets and seem fairly unremarkable at first glance. Yet faucet aerators are important components that we use on a daily basis.

Functions of faucet aerators

User comfort: aerators produce a gentle, splash-free water flow and shape the water stream to give it different patterns.
Reduced water consumption: Many models limit the flow rate at the faucet outlet. For hot water, this can also reduce the energy required to heat the water.
Standards and regulatory requirements: Depending on the model and application, aerators can help meet applicable national requirements for faucets.

Stream patterns

NEOPERL faucet aerators shape the water stream to give it different patterns. The spectrum ranges from laminar, aerated and spray to multi-stream. Our › video gives you a further impression of the various possibilities. They allow you to select stream shapes according to your individual requirements and design preferences.

Aerated stream

The aerator adds air to the water flowing through the faucet. This creates a soft, aerated stream that feels pleasant and plentiful.

Laminar stream

Thanks to its turbulence-free flow, the laminar stream appears crystal-clear and natural. Since no air is mixed into the water, this stream pattern is also suitable for use in hygiene-sensitive areas, depending on the specific technical and hygiene requirements.

Spray stream

The spray stream enables effective hand cleaning even at low flow rates. It supports efficient water use, especially in areas with frequent use.

Multi-stream

A multi-stream combines two different stream types in one aerator. The integrated switching function makes it easy to change between the two stream types.

Use aerators as problem solvers

Many models are available with additional features, for example, to save water, prevent limescale, increase user comfort, or improve the quality of the water stream through self-cleaning.

Helpful features

SLC: limescale protection

Thanks to the soft elastomer surface, you can easily remove limescale deposits on the underside of the aerator. Simply rub them off with your finger.

SSR: adjust the water stream angle

For aerators with SSR function, the angle of the water stream can be adjusted. This saves you having to replace the faucet if the water stream hits the basin at an angle that is less than optimal.

AC: automatic cleaning function

Aerators with a self-cleaning function automatically flush out solids up to 0.7 mm (0.03") in size. Especially in regions with high sand content, this feature can help reduce disruptions to the stream pattern caused by such solids and maintain stream quality for longer.

What is the flow rate of my aerator?

Aerators are available in many different flow rates. To help you navigate our range of products, we have developed a color coding system. Our watercolours concept makes it easy for you to distinguish between the various models in terms of flow rate and stream pattern. It also facilitates the production process and the procurement of spare parts.

Water-saving technologies in faucet aerators

Many NEOPERL aerator models limit or regulate the flow rate. This can reduce water consumption and, in the case of hot water, also lower the energy required to heat the water.

› Discover the technologies that are used to achieve this.

Stream shapers for non-pressurized water heaters

If you are using a non-pressurized water heater with low-pressure faucets, you will need a special stream shaper. Conventional aerator models create a pressure drop that is too high for these applications.

Neoperl offers the › NEOSTRAHL and FS Dripless stream shapers, which are specially designed for low-pressure faucets.

Low supply pressure

In low-pressure markets with a pressure range between 0.1-1 bar (1.4-14.5 psi), only the gravity generated in the building is responsible for the water pressure. The height of the water tank above the faucet determines the line pressure at the faucet/draw-off point.

A standard aerator cannot achieve aeration under these circumstances. Neoperl therefore offers special models that produce a comfortable, aerated stream of water even at low supply pressures.

Norms and approvals

Drinking water is our most important nutrient. Around the world, numerous mechanical and hygiene standards and approvals therefore apply to aerators and faucets in order to protect human health.

Noise-reduced models

One example is noise-reducing aerator models, which can help ensure compliance with relevant mechanical requirements. They are designed to reduce flow noise transmitted through the plumbing system—such as the noise in the pipes when water is drawn in a neighboring apartment.

The noise requirements for faucets in drinking water installations and their components are defined in Europe by standards such as EN 246.

Neoperl offers you a wide range of noise-reduced aerator models. All the necessary tests are carried out in-house, in our own sound laboratory.

How to remove and replace a faucet aerator

We show you how to replace a faucet aerator. This extends your faucet's lifespan, prevents scaling and ensures that the water stream is always pleasant and splash-free.
