Jyntrel single/double flange medium efficiency filters are panel filters built around high-throughput ultra-fine glass fibre media and an anodized aluminium alloy frame. They are rated E11 or E12 to EN 1822 and are used to remove sub-micron particles from HVAC systems, cleanrooms, hospitals, pharmaceutical and food facilities, electronics plants, data centres and energy storage installations. The filters are available in single-flange or double-flange configurations to suit standard duct connections or higher-integrity sealing requirements.
In service, the filter sits in the supply air path where the fan delivers a known volumetric flow against the resistance of the media, frame and any pre-filtration. The air approaches the face at a velocity determined by the filter area and the duct cross-section; the single-flange format guides the airstream through the frame, while the double-flange format presents a flange on both the upstream and downstream sides to limit bypass and to hold the media pack in place under higher differential pressure. Jyntrel specifies rated flows of 1000 m³/h and 500 m³/h for the 287 × 592 × 88 mm size at E11 and E12 respectively, and 2000 m³/h and 1000 m³/h for the 592 × 592 × 88 mm size. The anodized aluminium frame is light and corrosion-resistant, so it behaves predictably in humid or mildly aggressive airstreams and does not add significant weight to ceiling grids or FFU modules. The glass fibre media is intended for dry or conditioned air; the differential pressure across the filter should be monitored so that change-out occurs before the media collapses or the fan curve is pushed beyond its duty point.
EN 1822 E11 and E12 classifications place these filters in the sub-high-efficiency and high-efficiency bands, which is why they are frequently used as the final stage in HVAC systems and as prefilters ahead of HEPA stages in cleanrooms and FFUs. The high-throughput ultra-fine glass fibre paper provides a dense, uniform fibre matrix that captures fine particulate while keeping initial resistance within the capability of standard centrifugal and plug fans. The single/double flange construction is designed to reduce leakage at the frame-to-holder interface, an important detail when the filter is the last barrier before a controlled space. Because the frame is anodized aluminium, the filter is dimensionally stable and can be handled and installed without the weight penalty of heavier frames.
Selection starts with the system, not the filter. Jyntrel engineers need the device or system model, the available frame or duct dimensions, and a drawing or sketch if the interface is non-standard. Airflow rate is the next input: rated flow at the filter face determines the number of filters and the pressure drop budget. Operating conditions — temperature, humidity, presence of oil mist or corrosive vapour, and the differential pressure at which change-out will be triggered — complete the picture. For OEM and ODM projects, Jyntrel can adjust flange dimensions, non-standard airflow ratings and non-standard geometries, and supports custom frame materials, media grades, logo and packaging. The company has developed more than 1000 filter solutions, which shortens the path from specification to sample.

Jyntrel manufactures these filters in a 50,000 m² plant in Zhongshan, Guangdong, China, of which 20,000 m² is organised as six clean workshops. Multiple automated production lines support output in the millions of pieces per month, which gives buyers a stable supply base for standard and custom programmes. The company has more than 20 years of filter development and manufacturing experience and has been exporting to Europe, the United States, Japan and Korea for over 20 years. Quality control follows IQC, IPQC and OQC stages, and the in-house laboratory is CNAS-accredited and can issue test reports covering filter efficiency, dust holding capacity and resistance. Jyntrel holds ISO 9001, ISO 14001 and ISO 45001 certification and has held IATF 16949 automotive quality management certification since 2024. Products meet REACH and RoHS environmental requirements, and compliance documents can be supplied with shipments.
To receive a quotation, please send the device or vehicle model (where applicable), the required filter size or a drawing, the airflow or water flow of the system, the operating conditions (temperature, humidity and contaminant load), and the quantity required. Jyntrel will match these inputs to the appropriate E11 or E12 configuration and confirm flange format, frame and media options. Use the contact page to start the conversation.
The rated flows are defined for each standard size: 1000 m³/h (E11) and 500 m³/h (E12) for 287 × 592 × 88 mm, and 2000 m³/h (E11) and 1000 m³/h (E12) for 592 × 592 × 88 mm. Operating above these values raises pressure drop and may shorten service life. Jyntrel can review your face velocity and recommend a size or configuration that keeps the filter within its intended duty.
We need the design airflow in m³/h, the available filter face dimensions and the expected differential pressure at change-out. If the system is existing, the fan curve or the measured static pressure at the filter location is helpful. These inputs allow us to select E11 or E12 media and the correct number of filters.
The filters are classified E11 and E12 to EN 1822, which correspond to sub-high-efficiency and high-efficiency particulate filtration. Efficiency is maintained by the high-throughput ultra-fine glass fibre media and the sealed flange construction. For project-specific efficiency verification, Jyntrel can issue test reports from its CNAS-accredited laboratory.
Yes. Jyntrel supports OEM and ODM projects and can produce non-standard flange edge dimensions, non-standard airflow ratings and special geometries. Frame material, media grade, logo and packaging can also be customised. Please provide a drawing or sketch of the interface so the flange can be matched to your holder or duct.
Sample orders can be discussed with the sales team and are handled case by case. Because the filter must match your airflow and dimensions, we ask for the operating data first so the sample reflects the intended duty. Contact us through the inquiry form to arrange a sample and quotation.
For this product, standard specifications typically start at 50–100 pieces, while custom specifications usually start at 100–200 pieces depending on structural complexity; new customers and sample orders can be negotiated flexibly. Standard items are quoted at 7–15 days and custom production at 25–35 days. Multiple automated lines and raw material stock support urgent and long-term supply.
Replace the filter when the differential pressure reaches twice the initial resistance or 450 Pa, whichever comes first. Under normal HVAC conditions this typically corresponds to 6–12 months of service. Jyntrel can advise on differential pressure monitoring and full-lifecycle management to optimise total cost of ownership.
Yes. Jyntrel products meet REACH and RoHS environmental requirements, and compliance documents can be provided. The company has over 20 years of export experience to Europe, the United States, Japan and Korea and can support the documentation required for those markets. Please include your destination and documentation needs in your inquiry.
