This quartz sleeve is manufactured specifically for Aquacare 16 W UV lamps. With a length of 315 mm and a diameter of 25 mm, it acts as a protective barrier between the UV lamp and the water while efficiently transmitting UV radiation for optimal disinfection. Over time, the quartz sleeve is exposed to fouling and wear that can reduce UV output. We therefore recommend cleaning the sleeve once a year and replacing it every 3-5 years, as described in our guide to cleaning quartz sleeves. Key benefits: Fitted to Aquacare 16 W UV systems. 315 mm length and 25 mm diameter. Protects the UV lamp from water and damage. High-quality quartz glass with good UV transmission. Long service life with correct maintenance. Please contact us if you are unsure whether this quartz sleeve suits your system.
