Jyntrel ultra high-efficiency filters are mini-pleat panel filters rated U15 to U17, built to remove sub-micron particles from the supply air of cleanrooms, GMP suites, hospital operating rooms and FFU units. They are made for semiconductor and microelectronics plants, pharmaceutical manufacturers and HVAC engineers who need predictable efficiency at a defined airflow. The filter combines glass fibre or PTFE media with an anodised aluminium or stainless steel frame and hot-melt adhesive separators, so it holds its shape and its pressure drop across the whole operating range.
An ultra high-efficiency filter is a system component before it is a product. Its behaviour depends on what reaches it, how fast the air moves through it and what sits downstream. In a typical installation the air has already passed through G4 pre-filters and F8 or F9 intermediate filters; the U15–U17 stage then acts as the final barrier directly above the process or at the FFU outlet.
Velocity is the first variable to fix. Mini-pleat media packs a large surface area into a shallow depth, which keeps face velocity and resistance low for a given airflow. A 610 × 610 × 50 mm element is rated at 750 CMH and a 1170 × 570 × 50 mm element at 1300 CMH; the 1170 × 1170 × 70 mm size carries 3600 CMH. When a filter is run well above its rated airflow, resistance climbs and the pleats load unevenly, so we size the unit to the duty point rather than to the frame size alone.
Environment sets the material choice. Clean, dry recirculated air in a cleanroom is the simplest case. Hot exhaust from a metallurgical or energy process, corrosive traces in a battery materials plant, or humid air in a pharmaceutical suite each shift the frame and media decision — stainless steel instead of aluminium, PTFE instead of glass fibre. The 50 mm and 70 mm depth options allow the filter to sit in existing ceiling grids and FFU housings without changing the duct layout.
Efficiency is graded to EN 1822 across U15, U16 and U17, which corresponds to 99.9995%, 99.99995% and 99.999995% removal at MPPS. In practice this means the filter captures the 0.1–0.3 μm fraction that carries the most risk in semiconductor, lithium battery and precision manufacturing lines.
Low resistance is the second design target. A mini-pleat pack with hot-melt separators holds the pleats open and distributes airflow evenly, which supports energy savings over the service life rather than only at installation. The thin frame profile saves space in ceiling voids and FFU stacks, an advantage where headroom above the process is limited. Because resistance and efficiency are linked to the airflow you specify, we quote both together: a filter quoted at one duty point is not automatically the right choice at another.
Standard sizes cover many ceiling grids, but cleanroom layouts rarely match a catalogue exactly. Jyntrel offers non-standard dimensions and OEM service, drawing on a 20,000 m² clean workshop and a CNAS-accredited testing centre. Frame material, media type, separator format and labelling can all be specified.
To select correctly, send us the device or ceiling grid model, the available size or a drawing, the airflow in CMH at the filter face, and the operating conditions — temperature, humidity and any corrosive or oily content in the air. Quantity and target delivery date complete the picture. With those inputs we can confirm the efficiency grade, depth and frame material, and return a quotation with the expected resistance at your duty point.

In energy and metal smelting environments the same filter family is used at battery materials workshops, photovoltaic cell cleanrooms and powder metallurgy exhaust lines, where the material selection follows the gas chemistry rather than the particle load alone.
Jyntrel has more than 20 years of filtration research and manufacturing experience and has exported to Europe, the United States, Japan and South Korea for over 20 years, which supports stable long-term supply. Multiple automated production lines give monthly capacity in the millions of pieces, so repeat orders and volume programmes are not limited by manual assembly.
Production runs in a 50,000 m² plant that includes 6 clean workshops totalling 20,000 m², where high-efficiency elements are assembled in a controlled environment. Quality control follows IQC, IPQC and OQC stages through the process. The in-house laboratory is CNAS-accredited and issues test reports for filtration efficiency, dust holding capacity and resistance. The company holds ISO 9001, ISO 14001 and ISO 45001 certification and obtained IATF 16949 automotive quality certification in 2024; products meet REACH and RoHS requirements and compliance documents can be supplied.
The company is based in Zhongshan, Guangdong, China, and supports OEM/ODM across size, structure, media grade, frame material, logo and packaging, with more than 1,000 filter solutions developed to date.
Send the device or ceiling grid model, the size or a drawing, the airflow in CMH, the operating temperature, humidity and any corrosive content, and the quantity you expect. Our engineers will confirm the efficiency grade and depth, and reply with a quotation. Contact Jyntrel to start the selection.
It is designed around a rated airflow for each size: 305 × 610 × 50 mm at 350 CMH, 610 × 610 × 50 mm at 750 CMH, 1170 × 570 × 50 mm at 1300 CMH and 1170 × 1170 × 70 mm at 3600 CMH. Running well above the rated figure raises resistance and loads the pleats unevenly. Share your actual airflow and we will confirm the right size and depth.
We need the airflow in CMH at the filter face, the available size or a drawing, and the expected operating temperature, humidity and any corrosive or oily content in the air. Quantity and target delivery date complete the brief. With those inputs we can specify the U15–U17 grade, frame material and 50 mm or 70 mm depth.
The range covers U15, U16 and U17 to EN 1822, corresponding to 99.9995%, 99.99995% and 99.999995% at MPPS, capturing the 0.1–0.3 μm fraction. The grade is chosen against your cleanliness target and the upstream pre-filter chain. Tell us the required class and we will match it.
Yes. Non-standard dimensions and OEM service are available, with anodised aluminium or stainless steel frames and glass fibre or PTFE media. Customisation draws on a 20,000 m² clean workshop and a CNAS-accredited testing centre. Send a drawing or the grid dimensions and we will confirm feasibility.
Standard sizes typically start at 50–100 pieces; custom sizes usually start at 100–200 pieces depending on structure complexity, and terms for new customers and sample orders can be discussed. Standard stock ships in 7–15 days and custom production usually takes 25–35 days. Automated lines and material stock support urgent and repeat orders.
Service life depends on the upstream pre-filter configuration, airborne dust concentration and running hours; under normal conditions it is typically 3–5 years. Replace when final resistance reaches 2–2.5 times the initial resistance, confirmed by periodic leak testing. A G4 + F8/F9 + U15/U16 chain extends life and lowers total running cost.
Every element is scanned and leak-tested to EN 1822 in the CNAS-accredited laboratory, with resistance checked at the same time, and each unit carries a uniquely numbered test report. IQC, IPQC and OQC stages run through production. This gives batch-to-batch traceability for cleanroom and GMP audits.
Each filter carries a 12-month warranty, which can be discussed for specific operating conditions, and confirmed quality issues are replaced free of charge. The CNAS laboratory can support performance re-testing and issue reports. Our technical team also advises on installation and filter-chain optimisation — send your operating conditions through the contact page to begin.
