High Efficiency Filter (Mini-Pleat, Partitionless) — Jyntrel

The Jyntrel high efficiency filter is a partitionless mini-pleat panel filter that removes micron and submicron particles from air in HVAC and cleanroom systems. It is available in efficiency grades from M6 to U16 and is used in semiconductor fabs, pharmaceutical cleanrooms, hospital operating rooms, commercial buildings and FFU units. Facility engineers and OEMs specify it where low resistance, high efficiency and a slim profile matter.

Operating Conditions and Airflow Path

This filter sits in the final or pre-final stage of an air handling system, where air has already passed through coarser prefilters. Its partitionless construction uses hot-melt adhesive beads instead of aluminium separators, so the pleat pack is thinner and the open face area is larger for a given frame size. That geometry keeps face velocity lower at a given airflow, which reduces pressure drop and the energy needed to move air through the system.

Typical operating conditions include ambient temperatures in cleanrooms and HVAC ducts, relative humidity levels common to conditioned spaces, and face velocities that depend on the filter model and system design. The glass fibre or PTFE media is selected to suit the target efficiency and the particle challenge. In FFU units, the filter is often the last component before the air enters the clean zone, so a good seal between the filter frame and the housing is essential to prevent bypass.

For ducted HVAC systems, the filter can be installed in a holding frame or filter housing. The slim 50 mm or 70 mm depth allows retrofit into tight spaces where deeper filter packs would not fit. The low initial resistance helps maintain design airflow without overloading the fan, and the filter’s progressive loading behaviour means resistance rises gradually as dust accumulates.

Core Performance

Jyntrel high efficiency filters are rated from M6 to U16, covering medium efficiency through ultra-high efficiency classes. The filtration efficiency for 0.3 μm particles (or MPPS) ranges from 99.95% to 99.9995% at the H13 to U17 levels, depending on the grade selected. Each filter is tested for efficiency and scanned for leaks before leaving the factory.

The partitionless design reduces the risk of media damage during handling and provides a more uniform airflow distribution across the pleat pack. The anodised aluminium alloy or stainless steel frame gives structural rigidity without adding significant weight. The hot-melt adhesive separators are applied in a controlled pattern to maintain pleat spacing and prevent media flutter under airflow.

Because the filter has a low resistance for its efficiency class, it can help reduce fan energy in constant-volume systems or allow smaller fans in variable-air-volume systems. The slim profile also means more filters can be stored in the same space, which is useful for maintenance planning in large facilities.

Selection and Customisation: the Data We Need

To recommend the right filter, Jyntrel needs the following information from you:

• Your device or system model and the installation location (e.g. FFU, AHU, cleanroom ceiling grid).
• Required filter dimensions or a drawing showing the frame size and depth.
• Airflow rate (m³/h or CMH) and the corresponding face velocity, if known.
• Operating conditions: temperature, humidity, and any corrosive or reactive substances in the air stream.
• Required efficiency grade (M6 to U16) and any applicable standards.
• Quantity needed for the initial order and expected annual usage.

We can customise frame material (anodised aluminium or stainless steel), media type (glass fibre or PTFE), dimensions, and labelling. OEM/ODM orders are welcome. Our engineering team can also review your system’s airflow path and suggest the most suitable filter grade and size.

Parameters

Typical Applications

Jyntrel high efficiency filters are used in semiconductor and microelectronics cleanrooms, including FFU units, clean booths, and Class 10 to Class 10000 cleanrooms. They are also found in pharmaceutical GMP workshops, hospital operating rooms, and high-end commercial HVAC systems. Other applications include energy storage facilities, AI data centres, and food processing areas where particle control is required.

In semiconductor fabs, the filters protect lithography tools, wafer processing equipment, and packaging and testing areas. In pharmaceutical production, they help maintain the clean environment needed for sterile operations. In hospitals, they are used in operating theatres and other critical care spaces. Commercial buildings use them to improve indoor air quality and protect occupants and equipment.

Manufacturing and Testing at Jyntrel

Jyntrel operates multiple automated production lines with a monthly capacity of millions of pieces, supported by over 20 years of export experience to Europe, the US, Japan, and South Korea. Our 50,000 m² plant includes six clean workshops totalling 20,000 m², where filters are assembled and tested. The in-house laboratory is CNAS-accredited, so we can issue test reports for filtration efficiency, dust holding capacity, and resistance. We are certified to IATF 16949 (2024) and ISO 9001, ISO 14001, and ISO 45001, and our products meet REACH and RoHS requirements. Every filter undergoes IQC, IPQC, and OQC checks, and each unit is individually scanned for leaks before packing.
