The AQUA ULTRAVIOLET A00057 is a 57-watt ultraviolet sterilizer from the Classic Series, designed to eliminate algae, bacteria, and pathogens in recirculating water systems. Operating by exposing water to germicidal UV-C light as it passes through the unit, the A00057 features 2-inch inlet and outlet connections that integrate directly into existing plumbing runs. This unit is installed by licensed pool and aquatic system technicians as well as experienced pond and water feature professionals who require reliable biological control without chemical dependency.
The A00057 is suited for residential and light commercial applications including in-ground and above-ground pools, koi ponds, aquaculture systems, and water features where consistent UV sterilization is required. The 2-inch connection size accommodates higher flow systems compared to smaller-port UV units. The Classic Series design provides straightforward inline installation in standard plumbing configurations.
Designed as an OEM-style UV sterilizer for inline pool, pond, and aquatic system plumbing with 2-inch pipe connections.
Installation should be performed by a qualified pool or plumbing technician. Shut down the circulation pump and relieve system pressure before making any plumbing connections. The unit must be installed so that water flow direction matches the marked inlet and outlet ports. Lamp replacement and quartz sleeve service require powering down the unit completely and allowing internal components to cool before handling.
