The "Hybrid Capsule Filter" significantly extends the lifespan compared to conventional capsules while improving the internal structure, resulting in a cartridge filter with excellent fluid dynamics. It has reduced air pockets, enhancing startup performance on the line. The interior features a hybrid combination of high-precision five-layer media, ensuring reliable particle capture and gel removal. Additionally, it offers remarkably low pressure loss, high lifespan, and excellent dust collection capabilities, making it widely usable for small volume filtration such as photoresist, developer solution, pure water, and N2 gas filtration. 【Material Composition】 ■ Housing: Polypropylene ■ Media: P.P, Nylon 66, Polyether sulfone, PTFE *For more details, please refer to the external link page or feel free to contact us.

The "Candle Filter" is a cylindrical filter that effectively utilizes a large filtration area in a limited space. It is suitable for low viscosity requirements and is widely used in resin polymerization lines and fiber applications. By suggesting the appropriate filter type (tube type, tree type) and size for your housing, we can efficiently secure the filtration area and enable high flow rate filtration. Additionally, since all components are made of stainless steel (SUS304, 316L), they can be cleaned and reused repeatedly. 【Features】 ■ Dimension design according to specifications ■ Easy to install and remove ■ Wide filtration area *For more details, please refer to the external link page or feel free to contact us.

The "Leaf Disk Filter" is a disk-shaped filter that excels in pressure resistance and is suitable for high viscosity and high precision requirements. It is widely used in film applications. The filter features a unique TP retainer in its retainer section, which is expected to reduce pressure loss and extend lifespan, making it possible to use with high viscosity or large flow fluids, which was difficult with conventional products. Additionally, the use of the TP retainer allows for a simple structure, enhancing cleanability and reducing cleaning residues after regeneration. 【Features】 ■ Excellent durability ■ Capable of handling high viscosity and large flow ■ Superior cleanability *For more details, please refer to the PDF materials or feel free to contact us.
