Product Overview
The 400G Press-Type Filter Element Water Purifier is an efficient water treatment device based on reverse osmosis (RO) technology, featuring a press-type filter element structure. It is suitable for drinking water purification in residential, commercial, and industrial settings. Its core advantages include high flow processing capacity (400 gallons/day) and modular design, allowing for quick disassembly and replacement of filter elements, thereby reducing maintenance costs.
Core Technology and Structure
Multi-stage Filtration System
Stage One: 5μm PP cotton filter cartridge, intercepting rust, sediment, and other large particles.
Stage Two: Granular activated carbon (UDF), adsorbing chlorine, odors, and organic matter.
Stage Three: 1μm PP cotton (CTO), further filtering small particles.
Stage Four: RO reverse osmosis membrane (precision 0.0001μm), removing heavy metals, bacteria, viruses, and dissolved solids.
Stage Five: Mineral stone or UV sterilization (optional), enhancing water taste and ensuring safety.
Press-Type Filter Design
Features direct insertion installation, with filter elements tightly secured by mechanical pressure, avoiding leakage issues caused by loose traditional filters. The filter plates and frames are made of stainless steel or engineering plastics, resistant to corrosion and high temperatures, extending the service life.
Performance Parameters
Flow rate: 11.8L/H under standard pressure.
Suitable water quality: Municipal tap water, salt content ≤ 1000ppm.
Operating pressure: 0.15-0.3MPa, supports intelligent pressure regulation.
Installation method: Available in countertop or built-in options, suitable for kitchens, laboratories, and industrial production lines.
Application Scenarios
Residential: Kitchen water purification, compatible with direct drinking machines, solving secondary pollution of tap water.
Commercial: Restaurants, hotels, hospitals, and other high-flow water demand venues.
Industrial: Water purification for food processing and pharmaceutical industries, meeting GMP standards.
Advantages and Features
High Efficiency and Energy Saving: RO membrane recovery rate up to 75%, with a waste water ratio as low as 1:1.
Smart Control: Some models support TDS water quality monitoring and filter life reminders.
Eco-friendly Design: Replaceable filter elements reduce single-use material waste.
