Product Feature
Top-mounted valve for easy operation: The valve is mounted on the top, allowing for direct operation of backflushing and sewage discharge while standing, without the need for bending over.
Durable fiberglass tank: The winding process is a classic in the swimming pool industry, making it impact-resistant, crack-resistant, and reliable for years to come.
Sun-resistant and non-aging: The surface has an anti-UV coating, ensuring its appearance and performance remain consistent even when exposed to direct sunlight.
Pressure-resistant and fluctuation-resistant: It can withstand working pressure up to 250kPa, unaffected by temporary water pressure changes, and adaptable to various water supply environments.
6-position valve with comprehensive functions: One valve integrates 6 commonly used modes, eliminating the need for additional parts replacements, allowing even beginners to quickly learn how to use it.
ABS distributor prevents clogging: The water distribution system provides even water flow, preventing filter sand from clumping and ensuring more thorough rinsing.
Small size for flexible adaptation: A minimum diameter of 400mm can cover a flow rate of 4.68m³/h, suitable even for small swimming pools.
Low filter media cost: 0.5-0.8mm ordinary quartz sand is sufficient, eliminating the need to purchase expensive specialized filter media and saving money in the long run.
Standardized interfaces for easy connection: All interfaces are 1.5-inch, eliminating the need for pipe diameter changers on-site and saving labor time during installation.
Lightweight and easy to maintain: Weighing as little as 6.4kg, it can be easily moved by one person when changing sand or cleaning, without needing assistance.
