This is a no-partition medium efficiency filter that uses a mini-pleat design with glass fiber or PTFE media and hot melt adhesive separators to capture micron-sized particles. It is used in commercial HVAC, semiconductor cleanrooms, pharmaceutical GMP workshops, hospitals, and other environments requiring medium to sub-high efficiency filtration. Ranveth offers this filter with efficiency grades from M6 to E11, customizable sizes, and OEM service backed by a 20,000 m² cleanroom and CNAS-accredited testing.
The filter media is selected from high-quality glass fiber or PTFE, each chosen for specific performance characteristics. Glass fiber provides high dust-holding capacity and stable efficiency, while PTFE offers low resistance and resistance to moisture. The media is pleated into a mini-pleat configuration and separated by hot melt adhesive, which maintains uniform pleat spacing without the bulk of aluminum separators.
This pairing of media and hot melt adhesive separators directly affects airflow resistance and service life. The adhesive separators minimize pressure drop while keeping the pleats open, allowing a larger media area within a compact frame. The result is a filter that achieves efficiency grades M6 to E11 with low resistance and extended service life. The ultra-thin frame, available in anodized aluminum or stainless steel, saves space in crowded air handling units.

The filter is suitable for a range of applications where medium efficiency filtration is required. In commercial HVAC systems, it improves indoor air quality while maintaining low energy consumption. In semiconductor and microelectronics cleanrooms, it serves as a pre-filter for high-efficiency filters, protecting them from dust and extending their life. Pharmaceutical GMP workshops and hospital operating rooms rely on it to meet strict cleanliness standards.
Other applications include food processing, automotive manufacturing, data centers, and energy storage facilities. In these environments, the filter's low resistance and high dust-holding capacity contribute to energy savings and reliable operation. The filter can be used as a standalone solution or as part of a multi-stage filtration system.
To customize a filter for your specific application, please provide the following information: device or vehicle model, required dimensions or a drawing, airflow or water flow rate, operating conditions (temperature, humidity, dust concentration), and estimated quantity. Our engineering team will review your requirements and propose a suitable media and structure combination. We can also provide samples for testing before you commit to a bulk order.
