Product Introduction
Filter nozzles are made of ABS engineering plastic, featuring high pressure resistance and being unbreakable even when stepped on or knocked. The structure includes reinforced threads and added rubber washers, ensuring secure connections that never come loose. The base design enhances bottom seams, eliminating dead water zones between the filter plate and preventing sludge accumulation. Widely used in water treatment filters, filter tanks, combined and return-flow softening water systems, and ion exchange column equipment.
>Material Selection Long-handle filter nozzles are used in air-water backwash distribution systems for filter tanks; short-handle filter nozzles are applied in single-water backwash systems, gravity and pressure filter tanks, and ion exchange filter beds. Suitable for both domestic drinking water treatment and industrial water applications such as beverages, printing, dyeing, and swimming pools, as well as industrial wastewater and domestic sewage treatment projects.
