This is a direct replacement for the Wedeco QTZ36646 UV quartz sleeve. Also known as a WQR-1.
This UV quartz sleeve will be compatible with all Aquada, Ultima and Proxima models with a 1 designation.
This UV quartz sleeve has been manufactured with quality in mind. They are built to meet or exceed the quality of the Wedeco QTZ36646 UV lamp that they replace. This quartz sleeve is designed to operate in a UV disinfection unit for up to 5 years of constant running (just like Wedeco originals).
