The Neoperl CASCADE SLC Faucet Aerator (Part No. 400053023) is a highly reliable, pressure-compensating aerator designed to deliver a maximum flow of 2.2 gallons per minute. Incorporating Neoperl’s CASCADE internal structure and Smart Lime Care (SLC) coating, this model provides excellent long-term performance, reduced maintenance needs and a consistently stable water stream.
With the included housing, this aerator is easy to install and is ideal for retrofit projects, upgrades or new plumbing installations.
Key Features
Pressure-Compensated Flow (PCA 2.2 gpm Max)
The PCA technology keeps the water flow stable at a maximum of 2.2 gpm, even when water pressure varies. This prevents excessive water usage while ensuring a comfortable, predictable stream for everyday use.
CASCADE Technology
Unlike traditional mesh aerators, the CASCADE design uses a durable internal grid that resists clogging and maintains a steady flow pattern. This makes the aerator dependable even in hard-water areas where mineral buildup can quickly affect performance.
SLC – Smart Lime Care Surface
The SLC surface treatment dramatically reduces limescale adhesion. With its smooth, easy-clean finish, limescale can be wiped off effortlessly, improving hygiene and extending service life. This is especially beneficial in regions with hard water.
Complete Insert with Housing Included
This product comes with both the CASCADE insert and matching housing, ensuring proper fit and simplifying installation. This makes it particularly suitable for replacements or upgrades without the need for additional parts.
Comfortable, Controlled Stream
The aerator provides a smooth, consistent stream ideal for handwashing, rinsing and general faucet use. It improves user comfort while maintaining water efficiency.
Applications
Residential kitchens and bathrooms
Commercial washrooms
Office buildings and hospitality settings
Facilities with moderate to high water pressure
Hard-water locations where easy cleaning is essential
Water and Energy Performance
By limiting the flow to 2.2 gpm, this aerator helps reduce water consumption compared to older, higher-flow taps. This leads to lower hot-water usage, contributing to both water conservation and energy savings.
For buildings with many faucets, even minor flow reductions translate into substantial long-term savings.
