This is a single or double flange high-efficiency filter from Zanxis, rated E11 or E12 per EN 1822, and it captures fine airborne particles using high-throughput ultra-fine glass fiber media in an anodized aluminum frame. It is used in semiconductor cleanrooms, hospital operating rooms, pharmaceutical production, HVAC terminal filtration, and FFU systems. Zanxis supplies it in standard sizes and as custom OEM/ODM builds, with CNAS-accredited test reports available for verification.

Before you approve a sample, confirm the filter class and the rated airflow at your required size. For the 592 × 592 × 88 mm size, E11 is rated at 2000 m³/h and E12 at 1000 m³/h; the 287 × 592 × 88 mm size carries 1000 m³/h (E11) and 500 m³/h (E12). If your system operates at a different airflow, the pressure drop will shift, so ask for the resistance curve at your target flow. Also confirm the flange configuration (single or double) and the flange edge dimensions, because these determine how the filter seats in your FFU, ceiling grid, or duct connection. Finally, ask for the efficiency test report for the exact class and size you plan to order, not a generic datasheet.
The filter uses an anodized aluminum alloy profile frame, which keeps the unit light and corrosion-resistant. The media is high-throughput ultra-fine glass fiber paper, selected for E11 and E12 classes. The single-flange version suits standard FFU top-supply or ceiling recessed installation, while the double-flange version is intended for duct connections or pressure-differential applications where sealing on both faces matters. Typical installations include pharmaceutical and electronics cleanrooms, hospital operating rooms, HVAC terminal filtration, and FFU systems. Zanxis supports OEM/ODM customization of flange edge dimensions, non-standard airflow, and special shapes, so the filter can match existing ceiling grids and duct interfaces.
Zanxis operates a self-built laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment), which can issue test reports for filtration efficiency, dust holding capacity, and resistance. Production runs through IQC, IPQC, and OQC. The company holds IATF 16949 (achieved in 2024) and ISO 9001, ISO 14001, and ISO 45001 certifications, and products comply with REACH and RoHS requirements with documentation available. Manufacturing takes place in Zhongshan, Guangdong, China, across a 50,000 m² plant that includes six cleanrooms totaling 20,000 m². With more than 20 years of filtration R&D and manufacturing experience and exports to Europe, the US, Japan, and Korea, Zanxis has developed over 1,000 filtration solutions and runs multiple automated production lines.
To receive a sample and the corresponding CNAS-accredited test report, tell Zanxis your device or vehicle model, the required size or a drawing, the airflow or water flow, the operating conditions (temperature, humidity, and target efficiency), and the quantity you plan to order. Send these details through the contact page and the team will confirm the filter class, flange type, and sample lead time.
Yes. Zanxis has a CNAS-accredited laboratory that can issue reports for filtration efficiency, dust holding capacity, and resistance. The report covers the specific filter class and size you order, so you can verify the E11 or E12 rating and the pressure drop at your airflow.
Standard sizes can be sampled from stock, while custom sizes typically require 7–15 working days for sample preparation. The sample is supplied with its CNAS-accredited test report, and you should allow additional time for your own installation and pressure-drop checks.
For standard sizes, the MOQ is generally 50–100 units. Custom sizes and configurations usually start at 100–300 units depending on complexity. Zanxis can discuss flexible terms for first orders and sample quantities.
Standard products typically ship in 7–15 days. Custom orders usually take 25–35 days after sample approval. Zanxis maintains multiple automated production lines and material stock to support urgent and repeat orders.
Single-flange filters suit standard FFU top-supply or ceiling recessed mounting, where a compact, easy-to-replace unit is needed. Double-flange filters are intended for duct connections or pressure-differential applications that require sealing on both faces. Confirm your interface dimensions with Zanxis before ordering.
Yes. Zanxis supports OEM/ODM customization of flange edge dimensions, non-standard airflow, and special shapes. Provide a drawing or the required dimensions, and the team will propose a filter class and frame configuration that fits your system.
Replacement depends on the pre-filter efficiency, operating airflow, and ambient particle load. A common guideline is to replace when the pressure drop reaches twice the initial resistance. Zanxis can advise on a monitoring approach based on your actual operating data.
Please provide your device or vehicle model, the required size or a drawing, the airflow or water flow, the operating conditions (temperature, humidity, and target efficiency), and the quantity.
