The Ranveth ultra high-efficiency filter is a mini-pleat panel filter built for the most demanding cleanroom and critical HVAC applications. It captures sub-micron particles down to 0.1–0.3 μm at U15–U17 efficiency levels, using a choice of fiberglass or PTFE media. This filter is intended for semiconductor fabs, pharmaceutical GMP rooms, hospital operating theatres, and high-end commercial buildings where air cleanliness is non-negotiable.
What sets this filter apart is not a single material but the way media and structure are paired. We start with either high-quality glass fiber or PTFE membrane, selected for its filtration efficiency and resistance to airflow. The media is then formed into tight, uniform pleats, separated by hot-melt adhesive beads that keep the pleats open and stable. This mini-pleat geometry packs a large filtration area into a shallow frame, which directly reduces face velocity and pressure drop while extending service life. The frame—anodized aluminum or stainless steel—provides rigidity without adding unnecessary bulk, so the filter fits into compact installations such as fan filter units (FFUs).
Every material choice is validated in our CNAS-accredited laboratory, where we test filtration efficiency, dust holding capacity, and airflow resistance. That means the media pairing you receive is backed by measured data, not assumption. Whether you need the robustness of glass fiber or the chemical resistance of PTFE, the layer build is engineered to deliver stable performance across its service life.

The Ranveth ultra high-efficiency filter is deployed wherever airborne contamination threatens product quality or human health. In semiconductor and microelectronics manufacturing, it protects photolithography areas and wafer handling from particles that can cause defects. Pharmaceutical manufacturers rely on it in GMP cleanrooms to maintain sterile conditions for injectables and biologics. Hospitals specify it for operating theatres and isolation rooms to reduce surgical site infections. In high-end commercial buildings, it is used in HVAC systems to improve indoor air quality for occupants. It is also a common choice for FFU units in cleanroom ceilings, where its low profile and low resistance help reduce fan energy consumption.
Beyond these, the filter serves energy and metal smelting applications: lithium battery material production, photovoltaic cell manufacturing, nuclear power ventilation, and rare metal refining. In each case, the combination of high efficiency and low airflow resistance translates into lower operating costs and reliable protection.

The Ranveth ultra high-efficiency filter uses either high-quality glass fiber or PTFE media, paired with hot-melt adhesive as a separator. The media is pleated in a mini-pleat design to maximize surface area and minimize pressure drop. This combination delivers U15–U17 efficiency while maintaining low airflow resistance.
This filter achieves U15, U16, or U17 efficiency according to EN 1822, corresponding to filtration efficiencies of 99.9995%, 99.99995%, and 99.999995% at MPPS (0.1–0.3 μm). Each filter is tested in our CNAS-accredited laboratory, and we can provide test reports for efficiency, pressure drop, and dust holding capacity.
Yes. We offer custom sizes, frame materials (anodized aluminum or stainless steel), media type (glass fiber or PTFE), and other parameters. To tailor the filter to your needs, please provide your required dimensions, airflow rate, and operating conditions. Our engineers will recommend the optimal configuration.
For standard sizes, the MOQ is typically 50–100 pieces. Custom sizes may require 100–200 pieces depending on complexity. Standard products ship in 7–15 days, while custom orders usually take 25–35 days. We can accommodate urgent requests and long-term supply agreements.
Under normal operating conditions, the filter life is typically 3–5 years, depending on pre-filtration and airborne dust concentration. We recommend monitoring pressure drop and replacing when the final resistance reaches 2–2.5 times the initial resistance. Regular leak testing (e.g., PAO) also helps determine the right replacement time.
Yes, we can provide samples for evaluation. Please contact us with your specific requirements, and we will arrange samples and a quotation. Sample lead times vary by configuration but are typically within 7–10 days.
Our manufacturing facility is certified to IATF 16949, ISO 9001, ISO 14001, and ISO 45001. The filter itself is tested in our CNAS-accredited laboratory and can be supplied with test reports. We also comply with REACH and RoHS regulations and can provide compliance documentation.
