The Neoperl CACHÉ Coin-Slot Aerator (Part No. 423230450) is a compact and easy-to-maintain faucet aerator designed specifically for taps operating under low to moderate water pressure. With an optimal performance range between 0.2 and 1 bar, it ensures a stable, comfortable flow even where plumbing conditions would normally create weak or uneven water delivery. The coin-slot removal system and concealed CACHÉ design make this model ideal for both residential and commercial environments.
Key Features
Optimised for Low Pressure (0.2–1 bar)
This aerator is engineered to maintain smooth, usable water flow in low-pressure plumbing systems. It helps prevent splashing, weak flow and inconsistent stream formation—common problems in older homes and gravity-fed systems.
Coin-Slot Removal System
The top of the aerator features a practical coin-slot, allowing effortless removal using any standard coin. This simplifies maintenance, especially in hard-water regions where limescale must be cleaned periodically to maintain performance.
Concealed CACHÉ Design
The aerator sits inside the faucet spout, offering a clean, minimalist appearance. This hidden format also makes it tamper-resistant, an important benefit for public washrooms, commercial buildings and high-traffic areas.
Stable Water Stream
Even under low pressure, the aerator creates a controlled and comfortable stream, improving handwashing efficiency and reducing unnecessary water waste caused by splashing or irregular flow.
Durable Construction for Long-Term Use
Like all Neoperl CACHÉ aerators, this model is built from high-quality materials designed to resist limescale, wear, temperature changes and daily usage over extended periods.
Applications
Homes with low-pressure or gravity-fed systems
Older buildings with inconsistent pressure
Commercial washrooms requiring tamper-resistant aerators
Public facilities and high-traffic areas
Properties located in hard-water regions
Water and Energy Benefits
Although not designed for ultra-low flow rates, this aerator’s main benefit is flow stability. By shaping the water stream efficiently, it improves washing performance and reduces water loss from splashing. In many cases, this leads to more effective water use, especially at lower pressures where standard aerators fail to deliver a usable stream.
Installation and Maintenance Notes
Concealed CACHÉ format – check faucet compatibility
Remove or reinstall easily using a standard coin
Periodic rinsing recommended to maintain performance
Ideal for users wanting low-maintenance, tool-free servicing
Suitable for both domestic and commercial taps
