Evo 15w/25w Replacement Quartz

If your Evo UV is running but clarity has dropped – or the sleeve is cracked or scaled – it’s time to replace the quartz. The quartz sleeve protects the lamp and keeps UV-C output working properly.

The Evolution Aqua Evo 15w/25w Replacement Quartz Sleeve – is the correct replacement for Evo 15w and 25w UV-C units.

Why it matters

The quartz sleeve:

• Protects the UV lamp from water
• Allows UV-C light to pass through effectively
• Maintains proper algae control performance

A cracked or heavily limescaled sleeve reduces UV efficiency, even if the lamp is new.

When to replace

Replace the quartz sleeve if:

• It is cracked or chipped
• It is heavily scaled and cannot be cleaned
• You notice reduced UV performance despite a new lamp

It’s good practice to inspect the sleeve during your annual lamp change.

Fitting notes

• Unplug the UV-C unit before opening.
• Allow the unit to cool fully.
• Handle the quartz carefully – it is fragile.
• Check seals and O-rings during reassembly.

Never operate the UV unit without the quartz sleeve correctly fitted.

Clear water depends on strong UV output. Pair a fresh quartz sleeve with a new lamp for best results.
