Aqua Ultraviolet – TWIST 40 Watt UV Sterilizer, 2" (White)
Overview
Mid-size UV-C sterilizer with a flexible plumbing layout. The TWIST 40W adds a rotatable union block so you can “twist” the inlet/outlet orientation to match your run—cutting elbows, head loss, and install time. 2" slip ports support high-flow pond and aquarium loops.

Rotating (TWIST) union block aligns ports to your plumbing in tight spaces
-
Single 40W low-pressure UV-C lamp targets algae, bacteria, and protozoa
-
2" slip inlet/outlet for clean, high-flow PVC installs
