The Jyntrel no-partition medium efficiency filter is a mini-pleat panel filter that captures micron-sized particles across the M6 to E11 efficiency range. It is designed for commercial HVAC systems, cleanroom pre-filtration, and FFU units where low airflow resistance and space-saving construction matter. Facility engineers, HVAC contractors, and OEM equipment manufacturers specify it to protect downstream high-efficiency filters and maintain indoor air quality in demanding environments.
In a typical installation, the filter sits in the supply air path of an AHU or FFU, downstream of the pre-filter and upstream of the terminal HEPA stage. Air enters the pleated media at face velocity determined by the system design—often between 0.5 and 2.5 m/s—and passes through the glass fibre or PTFE medium, where particles are intercepted by mechanical and electrostatic mechanisms. The hot-melt adhesive separators maintain uniform pleat spacing, preventing media collapse under pressure and ensuring a stable airflow path even at higher velocities.
Because the filter has no aluminium separators, the open pleat design reduces turbulence and static pressure drop compared to conventional partitioned filters. This characteristic is particularly beneficial in variable air volume systems, where energy consumption is directly tied to fan power. The anodised aluminium alloy or stainless steel frame provides structural rigidity without adding significant weight, allowing the filter to be installed in ceiling grids or ducted housings with minimal support.
Operating temperature and humidity limits depend on the chosen media and frame, but the construction is compatible with standard HVAC environments. For high-humidity or corrosive conditions, stainless steel frames and moisture-resistant media can be specified. The filter is not intended for use where media may be exposed to water droplets or oil aerosols without appropriate pre-treatment.
The filter delivers medium efficiency filtration with a low initial pressure drop. The mini-pleat design maximises media area within a compact frame, resulting in high dust-holding capacity and extended service intervals. Efficiency grades from M6 to E11 cover a wide spectrum of particle sizes, with typical arrestance for particles above 0.5 μm ranging from 60% to 95% depending on the grade selected. This performance makes the filter suitable both as a standalone solution for commercial buildings and as a pre-filter for cleanroom applications.
Three key performance attributes define the product: low airflow resistance for energy savings, micron-level particle capture, and an ultra-thin frame that saves installation space. The filter is available in standard depths of 50 mm and 70 mm, with face dimensions from 305 × 610 mm up to 1170 × 1170 mm. Nominal airflow capacities range from 350 CMH for the smallest size to 3600 CMH for the largest, allowing engineers to match filter size to system airflow requirements.
To recommend the correct filter configuration, we require specific operating data. Please provide the device or system model, the required face dimensions or a dimensional drawing, the design airflow rate (in CMH or m³/h), and the operating conditions including temperature, humidity, and any corrosive or abrasive contaminants present. Additionally, inform us of the expected efficiency grade and whether the filter will serve as a pre-filter or final filter stage.
Jyntrel offers comprehensive customisation: non-standard sizes, alternative frame materials (anodised aluminium alloy or stainless steel), and media selection (glass fibre or PTFE) to meet specific efficiency and resistance targets. Our engineering team can also assist with OEM branding, including logo placement and packaging design. With a 20,000 m² clean workshop and a CNAS-accredited testing centre, we support prototype development and validation testing to ensure the filter meets your system's performance requirements.

The filter is widely used in commercial air conditioning and ventilation systems, semiconductor and microelectronics cleanrooms, medical and cleanroom facilities, pharmaceutical and food processing areas, automotive and mechanical manufacturing, AI computing and data centres, and energy storage facilities. In these environments, it serves as a critical barrier against particulate contamination, protecting both processes and downstream equipment. Its low-profile design is particularly advantageous in retrofit projects where space is limited.
Jyntrel operates multiple automated production lines with a monthly capacity of millions of pieces, ensuring supply stability for large projects and long-term contracts. With over 20 years of export experience to Europe, the United States, Japan, and South Korea, we understand the documentation and compliance requirements of international markets. Our 50,000 m² manufacturing plant includes six clean workshops totalling 20,000 m², where filter media cutting, pleating, frame assembly, and sealing are performed under controlled conditions to prevent cross-contamination.
Quality is managed through a three-stage control system: incoming inspection (IQC), in-process inspection (IPQC), and outgoing inspection (OQC). Our CNAS-accredited laboratory can test filtration efficiency, pressure drop, and dust-holding capacity, and we can provide test reports to support your validation and regulatory submissions. Jyntrel holds ISO 9001, ISO 14001, and ISO 45001 certifications, and has been certified to IATF 16949 since 2024. Products comply with REACH and RoHS regulations, and we can supply the relevant compliance documents upon request.
To receive a tailored solution, please contact us with the following details: your device or vehicle model (if applicable), required filter size or a drawing, airflow or water flow rate, operating conditions (temperature, humidity, contaminants), and estimated quantity. Our engineering team will review your requirements and respond with a recommendation, sample availability, and pricing. Contact Jyntrel to discuss your filtration needs.
The filter is designed for face velocities typical of HVAC systems, generally up to 2.5 m/s. The no-partition mini-pleat construction maintains uniform pleat spacing and prevents media flutter even at higher velocities, but for velocities above 2.5 m/s we recommend consulting our engineers to select the appropriate media and frame reinforcement.
We need the design airflow rate in CMH or m³/h, the available face dimensions, and the expected operating temperature and humidity. If the filter will be used in a system with variable airflow or frequent fan cycling, please mention that as well so we can recommend a suitable efficiency grade and media.
The Jyntrel no-partition medium efficiency filter is available in efficiency classes from M6 to E11, covering medium to sub-high efficiency levels. For particles above 0.5 μm, typical efficiency ranges from 60% to 95% depending on the grade selected. We can provide test reports from our CNAS-accredited laboratory to verify performance for your specific application.
