Import 5-Stage Ro Water System — Buy in wholesale FOB from Supplier in China

The 5-stage RO water system from Guangzhou Jiefa Filtering Equipment Co., Ltd. is an under-sink reverse osmosis unit designed around universal cartridge standards, with three flow-rate options: 50, 75, or 100 gallons per day (GPD). Stage one is a sediment filter using either NSF string-wound or melt-blown polypropylene cartridge; stage two is a UDF granular activated carbon filter; stage three is a CTO carbon block; stage four is the RO membrane with a stated 97% rejection rate; and stage five is a post-carbon polishing filter. The system employs a Chinese-made booster pump to maintain adequate pressure across the membrane, and all cartridges are of standard 9.75 inch (250 mm) length to allow cross-manufacturer replacements.

The universal cartridge format is a significant practical feature for buyers concerned with long-term maintenance and supply chain flexibility. String-wound sediment filters typically handle 5-20 micron nominal filtration, while melt-blown variants offer more consistent density gradients; the supplier offers either. The CTO carbon block stage is standard for chlorine, taste, and odour reduction before the membrane. The 97% rejection rate applies to the RO cartridge under test conditions, though feed water temperature, TDS, and pressure all influence real-world performance. The booster pump is described as best-quality Chinese made, but specific manufacturer, power consumption, and noise rating are not stated and should be confirmed.

Buyers for this system span residential households, small restaurants, office kitchens, and light commercial food-service operations across export markets. The 50GPD option suits single-family use, while 100GPD addresses higher demand or multi-point installations. Operating temperature range is 40-100F (5-38C), which covers typical indoor conditions but may require insulation in unheated spaces. The 1,320 gallon (5,000 litre) or six-month cartridge service life is typical for residential duty cycles. Buyers should confirm with Guangzhou Jiefa Filtering Equipment Co., Ltd.: exact booster pump specifications, whether NSF certification applies to the complete system or individual components, and the precise Incoterms and minimum order quantities available.

Guangzhou Jiefa Filtering Equipment Co., Ltd. is located at 137 Taipingyang Industrial Park, Xintang Zhen, Zengcheng Qu, Guangzhou 511340, Guangdong Province, China. The supplier holds a harbor trust tier on the platform with a 0.00% response rate and zero recorded average response hours, indicating no tracked inquiry history. The company operates from one of China's major manufacturing regions for water treatment equipment, with access to the Pearl River Delta supplier ecosystem.

The supplier profile does not state year of establishment, factory size, annual output, or specific quality certifications held. The description references NSF for filter cartridges and describes the booster pump and RO cartridge as best quality Chinese made, but no independent verification is provided. Buyers should request business licence verification, factory audit reports, and copies of any ISO 9001, NSF, or water safety certificates. The mention of continuous supply of replacement cartridges by SF Filter suggests a relationship with that supplier, but the nature of this relationship (distributor, partner, or affiliate) should be clarified directly with Guangzhou Jiefa Filtering Equipment Co., Ltd.
