Stainless Steel Pre-filter

1、304 stainless steel explosion-proof bottle

Integrally die-cast thickened 304 stainless steel housing with pressure & explosion resistance to avoid rust and leakage. It has passed 320,000 pulse tests and 50kg burst pressure tests. Built-in PPR lead-isolation liner physically separates water from stainless steel to block heavy metal precipitation, far more durable than ordinary plastic filter housings.

2、High-throughput water pressure regulation design

Max rated flow rate reaches 20 tons per hour, far exceeding conventional filters. Stable water pressure is maintained even with multiple water outlets in use or slightly clogged cartridges, ideal for large villas and commercial premises. High flow ensures simultaneous bathing and kitchen use without pressure interference for a smoother water experience.

3、Siphon self-draining quick-release buckle

No disassembly required. Siphon principle automatically flushes sticky dirt off the filter screen instantly. Flushing once every 1–2 months greatly extends cartridge service life. Quick-connect clips replace traditional wrenches for tool-free cartridge replacement, cutting maintenance time and labor.

4、Flexible installation that doesn't take up space

Supports single-stage or multi-stage series connection for full pre-treatment to deep purification. Compact design allows wall-mounted or floor-standing installation, fitting neatly into small utility rooms, under-kitchen cabinets, whole-house recirculation systems and 5-constant comfort systems without occupying extra space.

5、Ten-year full machine warranty

10-year full-unit warranty guaranteed. Stainless steel housing offers lifelong durability; only sealing rings and cartridges are standard consumables. It greatly reduces after-sales compensation pressure for decoration and engineering companies, widely recognized by high-end fine decoration, school, hospital and other long-term engineering projects.
