A workhorse UV-C sterilizer for medium–large ponds and serious aquarium systems. This Classic 57W model with 3/4" ports adds a manual wiper to keep the quartz sleeve clear between services—great for maintaining consistent UV output in high-load systems.
Classic housing with 3/4" inlet/outlet for easy inline plumbing
Single low-pressure 57W UV-C lamp for algae, bacteria, and protozoa control
Integrated manual wiper helps maintain sleeve clarity and stable performance
Weather-resistant (non-submersible) body for indoor or protected outdoor installs
Clear end cap shows lamp-on status; service-friendly layout
Note: Wipers are not recommended for saltwater use; using a wiper on saltwater can void the wiper warranty. Many marine installs choose the non-wiper version and clean the sleeve during lamp changes.

Quick start/installation guide
Plumb after mechanical filtration on a pressure line; avoid gravity-feed.
Use unions/valves to service and to tune flow to your target dose.
Operate the wiper with the lamp off and pressure relieved.
Protect from weather; do not submerge.
Replace the lamp every ~9–12 months of continuous use to maintain dose.
