T245330 OPEN End Quartz Sleeve for Wonder models PC-2 G287 Lamp (QJ24330)

This open-ended quartz sleeve, part number QJ24330 and also listed as T245330, is the correct replacement for Wonder UV PC-2 systems fitted with the G287 lamp. It fits over the lamp inside the PC-2 housing, keeping it dry while letting UV-C light pass through to disinfect the water flowing past. Fit a new sleeve when the existing one has scaled, clouded or is due its annual replacement.

Signs your quartz sleeve needs replacing

• Scale, cloudiness or scratching visible along the sleeve
• Brown or yellow discolouration on the glass
• Water starting to taste or smell slightly off
• The sleeve has been fitted for roughly 12 months

In the Wonder UV PC-2, the quartz sleeve surrounds the G287 lamp, keeping it completely dry while letting UV-C light pass through the glass to treat the water flowing around it. As scale, staining or scratching build up on the sleeve, less UV light reaches the water, so the system can quietly under-perform even while the lamp continues to light up normally. Fitting a new QJ24330 sleeve restores the transmittance the PC-2 needs to disinfect properly.
