About Us

Company Overview

GONGYI CITY JINHUI FILTER CO., LTD. focuses on the manufacture and supply of activated carbon products and desulfurization media. The company works with industrial buyers, distributors, engineering organizations and treatment-system operators who require filtration and purification materials supported by clear product information and practical order coordination.

Activated Carbon Product Range

The activated carbon range includes Coconut Shell Activated Carbon, Honeycomb Activated Carbon, Columnar Activated Carbon, Granular Activated Carbon and Powdered Activated Carbon. Each form is intended for a different handling and treatment method. Granular products are commonly used in fixed beds and filters. Powdered carbon is used in dosing processes. Columnar products are suited to packed gas-phase systems, while honeycomb products provide structured gas-flow channels for suitable air purification and VOC applications.

Product specifications are not selected by form alone. The treatment medium, contaminant type, concentration, flow, contact time, temperature, humidity, pH, equipment design and required result all need to be considered. Depending on the product, specifications may include particle size or dimensions, iodine number, hardness or compressive strength, moisture, ash, bulk density and other application-related values.

Desulfurization Media

The desulfurization media range includes Iron Oxide Desulfurization Media for suitable hydrogen sulfide removal systems. An effective product recommendation requires gas composition, inlet hydrogen sulfide concentration, target outlet level, flow rate, temperature, humidity, pressure, equipment dimensions and operating schedule. Actual replacement intervals depend on the project conditions and should be evaluated from operating data rather than assumed from a fixed period.

Markets and Applications

Jinhui Filter products are intended for applications such as drinking-water treatment, industrial wastewater treatment, process-water filtration, commercial and industrial air purification, odor control, low-concentration VOC adsorption, gold recovery and selected gas purification processes. The same product may perform differently under different operating conditions, which is why application data is reviewed before the final specification is confirmed.

Order Coordination

The company supports discussions covering product selection, samples, specifications, quality documents, packing, labels, pallets, quantity, destination and delivery schedule. Customers can provide an existing product specification for comparison or describe the problem that needs to be solved. Where appropriate, sample testing can be used to support the final selection.

Responsible Product Communication

Jinhui Filter aims to present product information accurately and avoid unsupported performance claims. Technical data is interpreted together with its test method, and project examples are used as references rather than universal guarantees. Customer names, order quantities, destinations and operating results are only published when the information is authorized and can be verified.

Our Working Principle

The working principle is straightforward: understand the application, identify the relevant product form, confirm the required specification, agree on documentation and packing, and organize delivery according to the order. This process helps reduce misunderstandings and gives both parties a clear basis for product evaluation and procurement.
