Import All Teflon String Wound Filter — Buy in wholesale FOB from Supplier in China

The All Teflon String Wound Filter from ARC Filtration System Co., Ltd is a depth-type filtration cartridge constructed entirely from PTFE (polytetrafluoroethylene) fibres wound in a controlled pattern around a central core. This design creates a graded density structure that captures progressively finer particles through the filter depth, with the 100% Teflon construction providing broad chemical compatibility across aggressive process streams. The string wound geometry maximises dirt-holding capacity while maintaining a low differential pressure drop, a combination that extends service intervals in continuous-flow industrial systems. ARC Filtration System Co., Ltd manufactures this filter in Hangzhou, Zhejiang Province, China, and lists it with multiple micron ratings to address varying process requirements.

PTFE fibre is the sole construction material, a choice dictated by its near-universal chemical inertness, thermal stability up to approximately 260 degrees Celsius, and extremely low extractable levels. The string wound format, as opposed to pleated membrane or melt-blown alternatives, offers higher particulate loading per unit area and simpler disposal characteristics. Typical industry applications for all-PTFE depth filters include aggressive solvent filtration, corrosive chemical clarification, and high-purity electronics manufacturing where metallic ion contamination must be minimised. The absence of any binder, adhesive, or support layer in the flow path eliminates potential contamination sources and simplifies validation for sensitive processes such as pharmaceutical active ingredient filtration or semiconductor photoresist handling.

Buyers of this filter include chemical processors, pharmaceutical manufacturers, food and beverage producers requiring chemically resistant filtration, and electronics fabs managing ultra-pure chemical distribution. The all-Teflon construction particularly suits processes involving hot concentrated acids, organic solvents, or oxidising agents that would degrade polypropylene, nylon, or polyester media. Trade terms including FOB and CIF are noted as available, though specific pricing, minimum order quantities, and lead times are not stated in the listing data and should be confirmed directly with ARC Filtration System Co., Ltd. Buyers should verify micron ratings offered, core and end-cap materials, and dimensional options to ensure compatibility with existing filter housings.

ARC Filtration System Co., Ltd is headquartered at No.358 Binwen Road in Binjiang District, Hangzhou, Zhejiang Province, 310052, China. The supplier holds a harbor trust tier classification on the platform, with a response rate of 0.00% and an average response time of zero hours recorded, indicating that direct communication channels should be tested early in the enquiry process. The company profile as presented does not disclose founding year, factory size, employee count, or annual turnover, so any assessment of manufacturing scale must rely on direct verification rather than inferred metrics.

The listing positions ARC Filtration System Co., Ltd as a specialist in filtration solutions, with this all-Teflon string wound filter representing a product aimed at buyers with demanding chemical compatibility requirements. No specific quality management system certifications, export licences, or third-party audit status are mentioned in the available data. Buyers should request evidence of ISO 9001 or equivalent quality system certification, material traceability documentation, and batch test data for extractables and particulate shedding to validate suitability for their intended application. The supplier's location in Hangzhou places it within the Yangtze River Delta manufacturing region, a logistical advantage for containerised export through Ningbo or Shanghai ports.
