About Wanfang Air Purification Equipment Co., Ltd. - Air Filters Supplier in China

China hosts Wanfang Air Purification Equipment Co., Ltd., which maintains an active catalogue of five products. The supplier lists items under the Air Filters category, including a V type secondary filter, a Mini pleated HEPA filter, a HEPA filter with clapboard, a generic Air filter, and a Pocket filter. These offerings are intended for indoor air quality improvement and agricultural ventilation systems. Although HS codes are not provided in the catalogue, the products fall within the broader air‑filter product family recognized in international trade.

All five items use standard industry terminology such as HEPA (high‑efficiency particulate air) and pleated configurations. The V type secondary filter typically functions as a pre‑filter in multi‑stage filtration systems, while pocket filters are common in high‑flow HVAC applications. The catalogue focuses on particulate removal equipment rather than chemical or odor control solutions. The supplier’s product set reflects a narrow but specific concentration on air filtration hardware.

Product Range and Specialties of Wanfang Air Purification Equipment Co., Ltd.

The catalogue comprises a V type secondary filter, a Mini pleated HEPA filter, a HEPA filter with clapboard, a general Air filter and a Pocket filter. In the air‑filter market, secondary filters are usually rated by MERV 8‑11 and serve to protect downstream high‑efficiency units. Mini pleated HEPA filters are often classified as H13 or H14, delivering 99.95 % to 99.995 % particle capture at 0.3 µm, and are built from glass‑fiber or synthetic media. HEPA filters with clapboard frames provide rigid support for high‑pressure drops, while pocket filters are supplied in folded‑pocket designs with surface areas ranging from 0.5 m² to 2 m² for large‑capacity air handling units. Typical specifications include pressure drop (Pa), filtration efficiency (%), and dimensions (mm), which buyers compare against system requirements.
