Davey KAQ-S AquaSheild Smart Dual Stage Ultraviolet Water Filtration System 20" x 4.5" With Cover (84LPM)

The Davey KAQ-S AquaShield Smart Dual Stage UV System with Protective Cover delivers reliable whole-house water purification for properties using rainwater, bore water, or surface water supplies. Designed to safeguard homes where water quality varies throughout the year, this system combines high-capacity dual filtration with powerful ultraviolet disinfection to produce safe, clean, great-tasting water for every tap.

A key advantage of the With Cover model is its fully enclosed weather-resistant housing, engineered to protect the UV chamber and filters from sunlight, dirt, and environmental exposure. This makes it ideal for outdoor installations, pump sheds, tank stands, and exposed service areas where equipment protection and longevity are essential.

Offering a generous 84 LPM flow rate, long-life UV lamp performance, and a user-friendly Smart controller, the AquaShield system is built for dependable water quality and low-maintenance operation—no chemicals, no taste alteration, and no complicated servicing.
