POOL SAND FILTER PREMIUM UNI 3 BAG BLACK (5 year Warranty) The Premium UNI 3 Bag Black Pool Sand Filter with 5 Year Warranty is engineered for pool owners who demand long term durability, structural strength and reliable filtration performance in harsh outdoor conditions. Unlike standard filters, this unit is built with multiple reinforced zones designed specifically to handle continuous pump pressure, high flow rates and long operating hours common in South African swimming pools. The tank features an extra reinforced seam around the centre of the body, strengthening the area most exposed to internal pressure. A reinforced multiport connection section prevents stress cracking where plumbing and valve weight place constant load on the tank. In addition, the lid seating band is reinforced to ensure secure sealing and long term resistance against warping and leaks. Manufactured from UV stabilised corrosion resistant polymer, the 565mm tank delivers consistent water flow and efficient filtration while resisting sun damage, chemical exposure and environmental fatigue. The matte black finish offers improved UV resistance while matching most modern pool pumps, creating a clean professional installation appearance. This filter is suitable for medium residential swimming pools and supports multiple filter media types, allowing pool owners to choose between traditional sand or modern high efficiency alternatives. With a full 60 month tank warranty, this filter is designed to provide dependable service season after season.

FREQUENTLY ASKED QUESTIONS What makes this filter stronger than standard modelsThis filter includes three reinforced structural zones including the tank seam, the multiport connection area and the lid seating band. These reinforcements significantly improve resistance to pressure stress and long term fatigue. Why is the reinforced seam importantThe centre seam experiences the highest internal pressure. Reinforcement reduces the risk of deformation or cracking over time. Why reinforce the multiport connection areaThe valve and plumbing add constant weight and vibration. Reinforcement prevents stress fractures at the connection point. Does the black colour offer benefitsYes. Black polymer provides improved UV resistance and matches modern pump finishes. Is the valve includedYes. A 6 way multiport valve is supplied with the filter. Can I use ECO glass instead of sandYes. The filter supports up to 90kg ECO glass media.
