The Neoperl CASCADE SLC Faucet Aerator (Part No. 400053033) is a high-quality, pressure-compensating aerator designed to deliver a stable maximum flow of 2.2 gallons per minute. Featuring the renowned CASCADE technology with SLC (Smart Lime Care) treatment, this aerator provides long-lasting performance, improved hygiene, and reduced maintenance—making it ideal for both residential and commercial applications.
With its included housing and precision-engineered PCA insert, this model guarantees consistent water use and reliable stream quality even when pressure levels vary.
Key Features
Pressure-Compensated Flow (PCA 2.2 gpm Max)
The PCA mechanism ensures the aerator maintains a maximum flow of 2.2 gpm, regardless of fluctuations in supply pressure. This prevents excessive water use and stabilises performance across a range of plumbing systems.
CASCADE Technology
CASCADE aerators are known for their robust internal design. Instead of using mesh screens that clog easily, the CASCADE structure channels water through a durable grid system that is resistant to blockage. This ensures a steady stream over time, even in harder water conditions.
SLC – Smart Lime Care Surface
The SLC surface treatment significantly reduces limescale adhesion. The smooth, silicone-like finish makes scale easy to wipe away, improving hygiene and prolonging the aerator’s lifespan—particularly beneficial in regions with high mineral content.
Complete Insert with Housing
This product comes as a full set, including the aerator insert and housing. This makes installation simple, ensures perfect compatibility, and greatly improves retrofit convenience.
Stable, Comfortable Water Stream
The aerator produces a controlled and comfortable stream suitable for everyday tasks such as washing hands, rinsing, and general use in kitchens and bathrooms.
Applications
Residential bathroom and kitchen taps
Commercial washrooms
Hotels, offices and public facilities
Locations with moderate to high water pressure
Properties in hard-water regions due to SLC protection
Water and Energy Benefits
With a capped 2.2 gpm flow rate, this aerator ensures controlled consumption while still providing a full, comfortable stream. For many older faucets that run at higher flows, installing this aerator can offer immediate water savings.
Reducing flow also reduces hot-water usage, supporting energy efficiency and lower utility costs—particularly valuable in buildings with large numbers of faucets.
Installation and Maintenance Notes
Comes with complete housing for easy installation
Suitable for faucets requiring standard CASCADE-type aerators
SLC surface allows quick cleaning with a simple rub
Ideal for both professional installers and DIY maintenance
Performs well in hard-water environments
