The Zanxis Separator Box Filter is a rigid box-style air filter with corrugated separators, available in efficiency classes G4 through F9 and in non-woven or glass-fibre media. It is designed to capture coarse and fine particulate matter in commercial HVAC, cleanroom pre-filtration, paint shops and industrial ventilation systems. This filter suits facility engineers, OEM buyers and contractors who need verifiable performance data before specification. Zanxis manufactures it in Zhongshan, Guangdong, China, and supports custom sizes and non-standard frames.

Before you approve a specification, confirm the efficiency class required for your particle size range. The Zanxis Separator Box Filter covers G4, M5, M6, F7, F8 and F9, and the test standard (EN 779 or equivalent) should be stated on the data sheet. Verify the media type—non-woven fibre or glass fibre—because dust holding capacity and initial resistance differ between them. Confirm the frame material (aluminium or galvanised steel) and the separator construction, as these affect rigidity at the rated face velocity of 2.5 m/s. For non-standard installations, check the actual frame dimensions against your duct or holding frame; the four standard sizes above are references, not limits. Finally, agree on the acceptance criteria for initial resistance, efficiency and visual defects before production.
Zanxis follows a sample-first process so that performance is verified before a purchase order is placed.
The filter uses a rigid box construction with corrugated separators that hold the pleats in place and resist deformation at high face velocities. The deep pleat pack provides a large filtration area, which supports high dust holding capacity and longer service intervals compared with flat-panel filters. The frame is available in aluminium or galvanised steel, and the media can be specified as non-woven fibre for general HVAC duty or glass fibre for finer filtration at F7–F9. Typical installations include pre-filtration ahead of high-efficiency terminal units in pharmaceutical and electronics cleanrooms, intake sections of commercial air-handling units, paint-shop dust removal and industrial high-velocity exhaust outlets. Because the box filter is self-supporting, it fits into standard holding frames and can be replaced without dismantling ductwork. For systems with non-standard dimensions, Zanxis produces custom frames to drawing.
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. The production base covers 50,000 m², including six clean workshops totalling 20,000 m². The company holds IATF 16949 (achieved in 2024) and ISO 9001, ISO 14001 and ISO 45001 certifications, and its products comply with REACH and RoHS requirements, with compliance documents available on request. Quality control follows IQC, IPQC and OQC stages across the process. With more than 20 years of filtration manufacturing and export experience to Europe, the US, Japan and Korea, Zanxis supports OEM/ODM projects covering size, structure, media grade, frame material, logo and packaging, and has developed more than 1,000 filtration solutions.
To receive a sample and the corresponding CNAS test report, please provide the following details: the device or system model, the required size or a drawing, the airflow rate or face velocity, the operating conditions (temperature, humidity, dust load), and the estimated quantity. With this information, Zanxis can confirm the recommended efficiency class and media, and issue a quotation. Contact our team to start the verification process.
Yes. Zanxis can provide test reports from its CNAS-accredited laboratory covering filtration efficiency, initial resistance and dust holding capacity. These reports are generated for the specific sample or production batch and can be shared for your verification.
Standard sizes can be supplied quickly, while custom samples are typically developed within 7–15 days. Validation time also depends on your own fitting and observation period. We recommend agreeing on acceptance criteria before mass production.
The filter is available in G4, M5, M6, F7, F8 and F9. Efficiency is verified by laboratory testing according to the applicable standard, and the test report states the class and test method. You can request the report for the exact class you intend to order.
Yes. Zanxis supports OEM/ODM projects including custom sizes, non-standard frames, media grade, frame material, logo and packaging. Provide a drawing or the exact dimensions of your holding frame, and we will confirm feasibility. The four standard sizes listed are references only.
For standard sizes, the MOQ is typically 50–100 pieces. Custom sizes are confirmed case by case depending on dimensions and materials. Please share your requirement for a specific MOQ proposal.
Standard products are usually shipped within 15–20 days. Custom products generally take 25–35 days. For large orders, we provide a precise delivery schedule based on production planning.
Replacement depends on the operating environment and the final resistance set for your system. Under standard commercial HVAC conditions, a service life of 12–18 months is typical, but actual life varies with dust concentration and running hours. Monitor pressure drop to determine the right interval.
Please provide the device or system model, required size or drawing, airflow or face velocity, operating conditions and estimated quantity. With these details, Zanxis can recommend the correct efficiency class and media and issue a quotation. <a href="/en/contact">Contact us</a> to proceed.
