Import Basket Filter Sn Series — Buy in Bulk from Supplier in China

The Basket Filter SN Series from Shanghai Sunfine Filtration Technology Co.,Ltd is a coarse or pre-filter unit designed to remove dirt, pipe scale, and particulate contaminants from liquid streams. Its large filtration area is intended to maximize dirt-holding capacity and extend service intervals between element changes. The filter housing permits element replacement without full line disassembly, reducing maintenance downtime. Shanghai Sunfine states that units can be customized to fit various pipeline sizes and configurations, though no standard connection sizes, pressure ratings, or material grades are specified in the source data. The supplier is located at Room 702, Unit 3, No.388 Pangu Road, Baoshan District, Shanghai 201900, China, with harbor trust tier classification.

Construction material is not detailed, though carbon steel with epoxy coating and stainless steel 304 or 316L are standard for industrial basket filters in this application class. The large filtration area relative to housing volume suggests a pleated or deep-pleated element design rather than a simple perforated basket, though this is inferred from the description rather than confirmed. Typical filtration ratings for SN-series coarse filters range from 40 mesh to 200 mesh (approximately 400 microns to 74 microns), with finer grades available as post-filters. Gasket materials, seal types, and maximum differential pressure across the element are not stated and must be requested from the supplier for proper system integration.

Primary applications include water treatment facilities, chemical processing plants, and HVAC systems where particulate protection for pumps, valves, and heat exchangers is critical. The filter functions as a first-stage guard, prolonging the life of downstream fine filters and sensitive equipment. Buyers should confirm with Shanghai Sunfine whether the SN Series is rated for continuous or intermittent duty, the maximum allowable operating pressure and temperature, and whether ASME VIII or GB150 pressure vessel certification applies. The listing mentions ISO and CE certifications without specifics; importers should request certificate scopes and validity dates. Trade terms offered are FOB and CIF, with L/C and T/T payment methods. No MOQ, price band, or lead time is specified in the available data.

Shanghai Sunfine Filtration Technology Co.,Ltd is headquartered in Room 702, Unit 3, No.388 Pangu Road, Baoshan District, Shanghai 201900, China. The company holds harbor trust tier status with a response rate of 0.00 and zero recorded average response hours. No establishment year, registered capital, employee count, or production facility ownership is stated in the available profile.

The supplier's product focus is filtration equipment for industrial liquid handling, with the SN Series Basket Filter representing a core offering. No information is provided about in-house testing capabilities, design engineering staff, or reference installations. The listing claims ISO and CE certification without specifying which standards (ISO 9001, ISO 14001, or other) or the certifying body. Buyers should request copies of current certificates, scope statements, and any pressure vessel design approvals. The company does not disclose annual turnover, export volume, or key client sectors beyond general references to water treatment, chemical processing, and HVAC markets.
