AI-Powered supplier vetting

SummaryHenan Aikefi Environmental Protection Technology Co., Ltd. is a China-based limited company in Henan operating as both a trading company and manufacturer/factory. It supplies filtration and water-treatment products, including filters, cartridges, reverse osmosis systems, and related equipment. The supplier reports ISO 9001 certification, two production lines, 11 employees, and 6–10 R&D engineers and quality-control staff. It offers 3D software design and multiple customization options. However, written corrective/preventive-action and complaint-handling procedures are absent, no SDK is available, no valid manufacturing-capacity contract with affiliated subcontractors is reported, and overseas warehouse and showroom capabilities are unavailable. Financial information is represented only by reporting years, without performance values. No customer cases are provided. A BV audit is listed with a report period from 2025-11-25 to 2026-11-24, but the evaluation result is recorded as “0” without interpretation.

Supplier typeThe supplier is identified as a limited company in China that operates as both a trading company and manufacturer/factory. Its stated business and product scope centers on filtration, water treatment, reverse osmosis, environmental equipment, and related materials.

CertificationsThe supplier reports holding ISO 9001 certification for its management system. The provided information does not identify the certification issuer, scope, or validity period, but it is explicit evidence of certification holding.

After-Sales capabilityThe supplier has inventory service capacity, but it reports no written procedures or records for corrective and preventive actions or effective customer-complaint handling. It also lacks overseas warehouse and showroom capabilities, indicating documented after-sales-process weaknesses.

R&D capabilityThe supplier identifies itself as a professional technical supplier, provides 3D software design services, and reports 6–10 years of total R&D engineer experience. However, it has no available SDK; overall innovation capability is supported in design services but cannot be fully assessed as a broader technical platform capability.

Product Q&A

Q:What is the filtration mechanism of this string wound cartridge?

It uses a depth filtration structure. The polypropylene yarn is wound around a central core, trapping particles throughout the media rather than only on the surface. This design provides high dirt holding capacity.

Q:hat applications is this cartridge suitable for?

It is commonly used as a pre-filter for reverse osmosis systems, boiler feed water, and general process water treatment. It is effective for removing larger particulate matter before water reaches finer downstream filters.

Q:Can this cartridge be cleaned and reused?

String wound cartridges are generally intended for single use. Slightly clogged cartridges may be rinsed under low pressure for short-term reuse, but dirt holding capacity will decline after cleaning.

Q:Is polypropylene suitable for food and beverage contact?

Polypropylene is available in FDA-compliant grades. If your application requires food contact approval, please confirm with us before ordering so we can supply the correct grade.

Q:What micron ratings do you offer?

We offer a range of micron ratings for string wound cartridges, commonly from 1 micron to 100 micron depending on your filtration requirements. Please contact us with your target rating.
