The Premium Uni 4 Bag Pool Sand Filter Black is engineered for pool owners who demand exceptional structural strength long service life and dependable filtration performance. Designed for medium to large residential swimming pools this premium filter focuses on build quality where it matters most under continuous pressure and high flow conditions.
The tank is manufactured from UV stabilised corrosion resistant polymer and features multiple reinforcement points. These include an extra reinforced seam around the tank body a reinforced section where the multiport valve connects and a reinforced band around the lid seating area. These structural enhancements significantly improve long term durability and reduce stress cracking often caused by repeated backwashing pressure fluctuations and outdoor heat exposure.
With a large 610 mm tank diameter the filter provides high media capacity and consistent water flow supporting effective debris removal and stable chemical distribution. The matte black finish improves UV resistance and delivers a clean modern appearance that integrates neatly with contemporary pool pump installations.
A side mounted six way multiport valve allows easy switching between filtration backwash rinse waste recirculate and closed modes. Backwash clarity is monitored through the integrated sight glass as this model does not use a pressure gauge. Filter media is not included and must be selected separately based on performance preference.
