The Oltaven panel high-efficiency filter is a finished filter that removes fine particles from air in cleanrooms, FFUs and critical equipment. It filters airborne particles down to 0.3 μm at efficiencies from H13 to U14, with some models reaching ULPA U15/U16. It is built for semiconductor fabs, cleanrooms, medical and food facilities, data centres and commercial HVAC systems. Oltaven manufactures the complete filter, not just the media, so media choice, pleating, framing and sealing are all controlled in-house.
A high-efficiency filter starts with media, but the finished performance comes from how that media is formed and assembled. The media determines the base efficiency and resistance; pleating and sealing decide how much of that potential survives in the finished product. At Oltaven, we produce the complete panel filter in our plant in Zhongshan, Guangdong, so every step from media handling to final testing is under one quality system.
Media choice sets the filtration class. Glass fibre media is commonly used for H13–U16 grades, while PTFE media can be selected for specific chemical or moisture conditions. The pleating process increases the media area inside a given frame size. More pleats can lower face velocity and resistance, but if pleats are too tight, airflow passages may collapse or particulate may bridge across the pleat tips. Oltaven balances pleat depth and spacing to reach the target efficiency without unnecessary pressure drop.
Framing and sealing hold the pleat pack in place and prevent air from bypassing the filter. The frame can be anodised aluminium, galvanised steel, stainless steel, MDF or plastic, depending on the installation and customer preference. Sealant choice affects both durability and cleanliness: hot-melt adhesive is used for pleat separation in many panel designs, while polyurethane or other sealants can be selected for specific housing interfaces. Oltaven confirms sealant and frame options with the customer during design, because these choices must match the filter housing and operating conditions.
Three outcomes matter most in a finished high-efficiency filter: efficiency, resistance and capacity. Each is influenced by a different combination of media and forming decisions.
Efficiency is primarily set by the media grade, but it is only guaranteed if the filter is sealed correctly. A leak path around the pleat pack or through a damaged seal can let unfiltered air pass, which lowers the effective efficiency of the installed filter. Oltaven tests finished filters for efficiency and performs scan leak testing on every unit before shipment, so the rated class reflects the performance of the complete assembly.
Resistance is the pressure drop across the filter at a given airflow. It rises with higher media density and higher face velocity. Pleat geometry also matters: a deeper pleat pack with well-spaced pleats can reduce resistance by increasing effective media area. In the finished filter, resistance is measured and recorded so that system designers can match the filter to the fan or FFU curve.
Capacity describes how much particulate the filter can hold before resistance reaches the change-out point. It is influenced by media area, pleat count and the upstream pre-filtration. A filter with more media area generally has higher dust-holding capacity, but the forming process must keep the pleats open so that the full media area is used. Oltaven works with customers to select a pre-filter arrangement that protects the final high-efficiency stage and extends its service life.
Oltaven panel high-efficiency filters are used where particle control is critical to product quality or process reliability. In semiconductor and microelectronics manufacturing, they serve wafer fabrication, photolithography areas, chip packaging and microelectronics assembly, typically in ISO Class 1–7 cleanrooms. They are also used as final filters in FFUs, clean transfer windows and laminar flow hoods.
Medical and cleanroom facilities use these filters in operating rooms, isolation rooms and GMP pharmaceutical production areas. Food processing plants install them to protect sensitive production zones. Data centres and AI computing facilities use high-efficiency filtration to protect servers from particulate that can accumulate on heat exchangers and electronics. Commercial HVAC systems and industrial manufacturing, including automotive and machinery plants, use panel high-efficiency filters where outdoor air or recirculated air requires fine particle removal before it reaches the occupied space or process.

Oltaven has more than 20 years of experience in filter research and manufacturing, with over 1,000 filtration solutions developed for customers across Europe, the United States, Japan, Korea and other markets. Our OEM/ODM capability is the foundation of this product: we build filters to customer drawings and operating conditions, and we support private-label programmes with logo and packaging customisation.
The production base covers 50,000 m² in Zhongshan, Guangdong, including six cleanrooms with a combined area of 20,000 m². Panel high-efficiency filters are assembled in these cleanrooms to avoid cross-contamination. Our in-house laboratory is accredited by CNAS, and we issue test reports for efficiency, dust-holding capacity and resistance. The quality system is certified to ISO 9001, ISO 14001 and ISO 45001, and in 2024 we obtained IATF 16949 certification for automotive quality management. Products comply with REACH and RoHS requirements, and compliance documents can be provided on request. Quality control covers IQC, IPQC, FQC and OQC throughout production.
Oltaven supplies finished filters, not just media. Our OEM/ODM process is designed to turn a requirement into a tested, repeatable product.
This workflow has been used to develop more than 1,000 filtration solutions, and it allows us to keep the finished filter’s efficiency, resistance and capacity aligned with the customer’s system.

Two filters with the same outer dimensions can have different pressure drop because the media grade, pleat count and pleat depth may differ. A filter with more effective media area and well-spaced pleats generally has lower resistance at the same airflow. Oltaven measures resistance on the finished filter so the value reflects the complete assembly, not just the media.
An OEM project starts with a requirement review. We ask for the device or housing dimensions, target efficiency, airflow and operating conditions. From there, our engineers propose media, frame and sealant options, build a sample and test it at our CNAS-accredited laboratory before production.
Yes. Oltaven panel high-efficiency filters can be customised by dimension, media (glass fibre or PTFE), frame material (anodised aluminium, galvanised steel, stainless steel, MDF or plastic), sealant and separator type. Custom work follows a drawing or the actual operating conditions, and the final specification is confirmed on the sample.
The panel high-efficiency filter is available in H13 and H14 grades, with some models reaching ULPA U15/U16. Efficiency for 0.3 μm particles can reach 99.99% depending on grade. Each finished filter is tested for efficiency and scan leak integrity at our CNAS-accredited laboratory before shipment.
Yes. We provide samples for evaluation and quotations based on the confirmed specification. To quote accurately, we need the size or drawing, airflow, operating conditions and estimated quantity. Sample lead time is confirmed when the design is agreed.
For standard sizes, the MOQ is generally 50–100 pieces; custom sizes typically start at 100–200 pieces depending on structural complexity. Standard products ship in 7–15 days, while custom orders usually take 25–35 days for bulk production. We can discuss flexible arrangements for new customers and sample orders.
Service life is typically 1–3 years, depending on air cleanliness, face velocity, pre-filtration and daily operating hours. In normal cleanroom operation, replacement is recommended when final resistance reaches twice the initial resistance or the designed final resistance. A suitable pre-filter can extend the life of the final high-efficiency stage.
