The 10 pieces/lot Air Filter Element K46-M8527-C0 KHY-M8527-B0X are suitable for your Yamaha Chip Mounter YS12:

Yamaha YS12 SMT Filter - It is made of high-performance hot-melt non-woven fabric with fracture resistant organic synthetic fiber structure.
Yamaha YS12 SMT Filter - Incremental structure, the use of gradual densification multi-layer technology, that is to say, the fiber density toward the direction of pure air gradually increases, with higher filtering efficiency, which can be blocked in different density levels according to the size of dust, and more dust can be more effectively contained.
Yamaha YS12 SMT Filter - After the filter material is fully impregnated with glue, the dust particles cannot pass because the adhesive completely penetrates the medium, so that the air flow of the comprehensive filtration can spread evenly, forming a laminar flow state, and achieving the best spraying effect.
