The Zanxis single/double flange medium efficiency filter is a panel filter with an anodized aluminum frame and high-performance glass fiber media, rated E11 or E12 according to EN 1822. It captures submicron particles in HVAC systems, cleanrooms, and FFU units, and is used by pharmaceutical, electronics, healthcare, food processing, automotive, data center, and energy storage facilities. This page is written for engineers and QA teams who need to confirm parameters, verify performance with samples and lab reports, and sign off on specifications before ordering.

Before selecting a filter, confirm the following parameters with your process or facility team:
Documenting these values early reduces the risk of performance gaps and simplifies sample validation.
We recommend a structured sample verification process to confirm that the filter meets your specifications:
This workflow ensures that the filters you receive match the verified sample.
The Zanxis single/double flange medium efficiency filter is built with an anodized aluminum alloy frame that is lightweight and corrosion-resistant. The glass fiber media is pleated to provide a large filtration area within a compact panel. The single-flange design suits standard duct connections, while the double-flange design adds flanges on both the upstream and downstream sides for enhanced sealing—particularly useful in cleanrooms, pharmaceutical facilities, and high-pressure-drop systems.
These filters are commonly used as terminal filters in HVAC systems, pre-filters for HEPA units in cleanrooms, and in fan filter units (FFUs). They help protect downstream equipment and maintain air quality in sensitive environments. The E11 and E12 classes make them suitable for applications ranging from general commercial ventilation to critical pharmaceutical and electronics manufacturing.
Installation should follow standard practices for panel filters: ensure a tight seal against the frame, avoid media damage during handling, and monitor pressure drop to determine replacement intervals. With proper installation and maintenance, these filters contribute to energy-efficient operation and reliable air quality.
Zanxis operates a CNAS-accredited laboratory that issues test reports for filtration efficiency, dust holding capacity, and resistance. These reports provide verifiable data for your qualification process. Our quality management system is certified to ISO 9001, ISO 14001, and ISO 45001, and in 2024 we obtained IATF 16949 certification for automotive quality management.
Production takes place in a 50,000 m² manufacturing facility, which includes 20,000 m² of cleanroom space across six cleanrooms. Multiple automated production lines support monthly output in the millions of pieces. Quality control follows IQC, IPQC, and OQC procedures at incoming, in-process, and outgoing stages, ensuring consistency and traceability. Our products comply with REACH and RoHS environmental regulations, and compliance documentation is available upon request.
With over 20 years of experience in filter development and manufacturing, we have supplied customers in Europe, the United States, Japan, and South Korea. Our OEM/ODM capabilities cover dimensions, structure, media grade, frame material, logo, and packaging, with more than 1,000 filter solutions developed to date.
To request samples or test reports, please provide the following information so we can respond accurately:
Submit your request via our contact page. Our team will review your specifications and provide a detailed response, including sample lead time and test report availability.
Yes. Our CNAS-accredited laboratory issues test reports for filtration efficiency, dust holding capacity, and resistance. These reports are available for sample and production batches upon request.
Sample production typically takes 7–15 days, depending on the complexity of the configuration. Testing and reporting add a few additional days. We recommend planning for a total of 2–3 weeks for the complete validation process.
For custom sizes, the MOQ is generally 100–200 pieces, depending on structural complexity. We can discuss flexible arrangements for first orders or sample quantities.
Standard sizes are typically shipped within 7–15 days. Custom orders usually require 25–35 days for mass production after sample approval.
Replacement frequency depends on operating conditions and pressure drop. We recommend replacing the filter when the pressure drop reaches twice the initial value or 450 Pa, whichever comes first. In clean environments, this may correspond to 6–12 months of service.
Yes. We offer OEM/ODM services including custom dimensions, flange edge sizes, media grades, frame materials, logos, and packaging. Provide your specifications or a drawing for review.
Please provide the device or system model, required filter size or drawing, airflow, operating conditions, and estimated quantity. This allows us to propose the most suitable configuration and provide an accurate quote.
Yes, we provide samples for evaluation. Sample costs and lead times depend on the configuration; please contact us with your requirements to discuss the details.
