Special Advantages
High-Precision Filtration for Ultra-Clean Water
Uses DE precoat technology to achieve 1-3μm filtration with over 99% particle removal. Effluent turbidity <0.1NTU, vastly superior to sand filters.
Regenerable Filter Media for Eco-Friendly Operation
Supports reuse of DE and perlite, reducing replacement frequency and backwash water. Saves costs and promotes sustainability.
Smart Load Adjustment for Enhanced Durability
Automatically adjusts operation based on water quality and flow, optimizing energy use and extending filter media life.
Water Hammer Protection for System Safety
The soft starting/stopping technology prevents water hammer impact, protecting equipment and piping, and enhancing system stability and longevity.
Intelligent Control System for Easy Operation
Integrated PLC system allows one-touch switching between precoat, filtration, and regeneration modes. Fully automated, no manual monitoring required.
Highly Integrated Design for Space Efficiency
Combines pump, dosing tank, filter, and control system into a compact unit. Takes up only half
the space of traditional systems for faster installation.
Ultra-Quiet Performance for Comfortable Environments
Features a 4-pole low-noise pump and optimized flow design for noise reduction – ideal for high-end hotels and clubs.
Multi-Media Compatibility for Greater Flexibility
Works with a variety of filter media including DE and perlite, allowing flexible adaptation to different pool and spa water treatment needs.
Regenerative Media Filtration System – An All-in-One Premium Water Treatment Solution
High-Precision Filtration
Utilizing diatomaceous earth (DE) precoat membrane filtration technology, the system delivers 1–3 μm filtration accuracy and captures over 99% of suspended solids, parasites (e.g., Cryptosporidium), and fine particles. Effluent turbidity remains stable at <0.1 NTU, delivering cleaner and safer water.
Intelligent PLC Control
Equipped with a PLC-based smart control system, the unit automatically switches between precoat, filtration, and regeneration modes, reducing manual operation and ensuring efficient, stable system performance.
Flexible Filter Media Compatibility
Compatible with both diatomaceous earth (DE) and perlite, providing strong adaptability to different water conditions and filtration requirements.
Wide Range of Applications
Ideal for swimming pools, water parks, hot springs, and upscale hospitality venues where high water quality and reliable filtration performance are required.
