A high-efficiency panel filter with a single- or double-flange frame, built for terminal filtration in HVAC systems, cleanrooms and fan filter units (FFUs). It removes fine particulate from the air with high-performance glass-fibre media rated E11 or E12 to EN 1822, housed in an anodized aluminium alloy profile. Jyntrel supplies it to semiconductor and microelectronics plants, hospitals and cleanrooms, pharmaceutical and food production, automotive and machinery works, data centres and commercial ventilation systems.
The filter sits at the end of the air path, directly before the space it protects, so its behaviour is best described by what reaches it. Air leaves the upstream duct or plenum, crosses the flange face, passes through the glass-fibre media and enters the room or FFU outlet as filtered supply air. The flange is the mechanical interface between the filter and the housing; the single-flange version seats on one face, the double-flange version presents a sealing face on both sides for ducted or higher-pressure connections.
Two rated sizes cover the common terminal positions. The 287 × 592 × 88 mm unit is rated 1000 m³/h at E11 and 500 m³/h at E12. The 592 × 592 × 88 mm unit is rated 2000 m³/h at E11 and 1000 m³/h at E12. The E12 rating at half the E11 airflow reflects the higher pressure drop of the tighter grade at the same face area; where the system can accept the higher resistance, the same frame delivers the higher efficiency.
Because the depth is 88 mm, the filter fits standard terminal housings and ceiling grids without changing the duct layout. The anodized aluminium frame keeps the unit light enough for one-person handling during change-out while resisting corrosion in humid supply air. For design purposes, treat the rated airflow as the upper operating point and confirm the actual face velocity against the fan curve and the final resistance allowed by the system.
The separating element is high-throughput ultra-fine glass-fibre filter paper, selected for consistent efficiency across the face rather than for a single spot reading. E11 (sub-high efficiency) and E12 (high efficiency) are the two grades offered under EN 1822, so the specification language matches what European and export HVAC schedules already use.
The single/double flange construction is the anti-leak feature: the flange provides a defined seating face, and the double-flange version gives a sealing face on both sides where the housing or duct connection demands it. This matters most in terminal positions, where a bypass path around the media would carry unfiltered air straight into the clean space.
The anodized aluminium alloy profile is light and corrosion-resistant, which keeps the frame stable over repeated change-outs in humid or conditioned air. Media, frame and flange work as one panel; there are no separate gaskets or fittings to align on site beyond the housing interface itself.
Selection starts with the duty point, not the part number. Send the required airflow per filter, the acceptable initial and final pressure drop, and the space available at the mounting position. From these, the rated 1000/2000 m³/h figures at E11 and 500/1000 m³/h at E12 tell us whether a standard size fits or a non-standard one is needed.
Jyntrel supports OEM/ODM work on flange edge dimensions, non-standard airflow ratings and special shapes, as well as frame material, media grade, logo and packaging. More than 1000 filter solutions have been developed to date, so unusual housing dimensions are a normal request rather than an exception. A drawing or a dimensioned sketch of the housing is the fastest route to a firm proposal.

Jyntrel has more than 20 years of filter development and manufacturing experience, and has exported to Europe, the United States, Japan and Korea for over 20 years. That export history is the practical basis for supply stability on repeat programmes.
Production runs on multiple automated lines with a monthly capacity of several million pieces, so standard sizes and volume custom orders can be scheduled together. The plant covers 50,000 m², including six cleanrooms totalling 20,000 m², where high-efficiency filters are assembled and packed.
The in-house laboratory holds CNAS accreditation and issues test reports on filtration efficiency, dust holding capacity and resistance. Quality control follows IQC, IPQC and OQC across the production flow. The company holds ISO 9001, ISO 14001 and ISO 45001 certification and has held IATF 16949 automotive quality certification since 2024; products meet REACH and RoHS requirements, with compliance documents available on request. The factory is in Zhongshan, Guangdong, China.
To quote accurately, we need the device or housing model, the size or a drawing of the mounting position, the airflow or water flow through the filter, the operating conditions (temperature, humidity, upstream filtration, permitted final resistance) and the quantity required. Send these through the contact page and we will confirm the grade, the size and the flange configuration for your system.
Each size has a defined rated airflow: 1000 m³/h at E11 and 500 m³/h at E12 for the 287 × 592 × 88 mm unit, and 2000 m³/h at E11 and 1000 m³/h at E12 for the 592 × 592 × 88 mm unit. Treat the rated figure as the design point and check the resulting pressure drop against your fan curve and final-resistance limit. If your face velocity is higher than the rated point, a larger face area or a different configuration should be selected.
Send the required airflow per filter, the grade you need (E11 or E12), the acceptable initial and final pressure drop, and the dimensions of the housing or ceiling grid. A drawing of the mounting position helps us confirm the flange edge and whether a single- or double-flange version fits. With those figures we can match a standard size or propose a custom one.
Yes. Jyntrel offers OEM/ODM production covering flange edge dimensions, non-standard airflow ratings and special shapes, as well as frame material, media grade, logo and packaging. More than 1000 filter solutions have been developed to date. Send a dimensioned drawing and we will confirm feasibility and the tooling or sample route.
Standard sizes can be sampled; custom samples involve tooling and sampling costs, and the sampling lead time is typically 7–15 working days, with a full CNAS laboratory test report supplied with the sample. Sample and tooling charges are handled case by case and can be credited against a volume order. Tell us the size and grade you want to evaluate through the contact page.
For OEM/ODM customers, the MOQ for standard specifications is typically 50–100 units, while custom specifications usually start at 100–300 units depending on structural complexity. New customers and sample orders can be discussed flexibly. Confirm the exact figure with your quotation request.
Standard items are typically delivered in 7–15 days, and custom volume orders usually take 25–35 days. Multiple automated lines and stocked raw materials support urgent orders and long-term repeat supply. Lead time is confirmed with the quotation once size, grade and quantity are fixed.
Replacement is driven by the final resistance limit set for your system rather than by a fixed calendar interval. In demanding cleanroom duty with adequate pre-filtration, service life is typically 3–5 years, with change-out at twice the initial resistance as a common criterion. Jyntrel can help you set a resistance monitoring and replacement plan for your operating conditions.
Each filter is packed in a PE moisture-barrier bag with EPE foam corner protection, then in a five-layer corrugated carton fixed on a wooden pallet, so the media is not compressed or deformed in transit. Packaging can be printed with your logo, specification labels and barcodes. Ask for the packing details with your quotation.
