The LS-YW-8 smoke generator produces high-concentration steam (particle size range: 1-10μm, concentration over 80%), with high visibility and no pollution. After the steam is dispersed in a clean room, there are no residues. According to ISO 14644-3 and GMP regulations, the acceptance of clean rooms requires an evaluation of air flow direction. The LS-YW-8 smoke generator is suitable for clean rooms, local clean environments, air flow pattern filming, and is widely used in semiconductor and pharmaceutical clean rooms.
