YTF-Liquid-Sealed High-Efficiency/Ultra-High-Efficiency Frameless Air Filters (HEPA/ULPA) are suitable for high-level cleanrooms in electronics, biological, and pharmaceutical industries, as well as air purification equipment and other applications requiring strict control of air pollution. All models can be customized to meet specific site conditions to maximize application satisfaction.

YTF-Liquid-Sealed High-Efficiency/Ultra-High-Efficiency Frameless Air Filter Product Features:

Liquid-Sealed Design for High Seal Quality

Internationally advanced liquid-sealed adhesive design, offering excellent chemical stability, corrosion resistance, mildew resistance, and low bacterial growth. With moderate hardness, it maintains excellent sealing even after repeated disassembly and assembly and a period of settling.

Strict Material Selection, Extremely Low Chemical Volatility

All components are made from materials with extremely low chemical volatility, meeting the requirements of conventional cleanrooms and air filtration equipment.

Compact Structure, Easy Installation and Replacement

The YTF-Sealed frame is made of extruded aluminum profile. Imported phosphate-free polyurethane adhesive is used to seal the waterproof and flame-retardant fiberglass filter element, which is separated by hot-melt adhesive, further supplemented by a protective mesh, gaskets, and other components. Compact structure, small and lightweight, easy to install and replace.

Separator-free structure, low resistance, and good energy efficiency.

Using specially designed hot melt adhesive to separate the HEPA filter paper, ensuring uniform and reasonable spacing between the filter papers. This maximizes the utilization of the filter paper, achieving uniform airflow and low resistance.

Efficiency tested according to EN1822 to ensure compliance.

According to EN1822 standards, the filter efficiency is tested using a PMS laser particle counter and PSL particle size distribution method with MPPS (easily penetrating particle size) to ensure that the filter efficiency meets requirements.
