400GPD High-Flow Reverse Osmosis (RO) Membrane Element

RO System

A reverse osmosis (RO) water filter system that is installed under the sink and does not use a pump is known as a gravity-fed reverse osmosis system. These systems rely on water pressure from the incoming water supply to push water through the RO membrane. Manufactured at our 20,000+ m² ISO 9001:2015 certified facility in Yuanhua Town, Haining City, Zhejiang Province, China, this product is part of our full-stack water filtration line — independently tested to NSF/ANSI 42 & 53 standards by SGS, with CE marking for European import compliance and FDA-grade material declarations on request. OEM/ODM private-label customization is available: brand printing, custom end-cap molding, color matching and packaging. Standard MOQ from 1,000 pcs; bulk wholesale FOB Shanghai/Ningbo with T/T 30/70 or L/C at sight payment terms. We currently export to 50+ countries including the United States, Germany, Russia, Saudi Arabia, Malaysia, Indonesia and Brazil, with full halal (JAKIM) certification on file for Muslim markets.
