The Yanxin Anti-fall Ceiling Device is a specialized safety and purification integrated equipment developed for the ceiling system of large-scale clean rooms. It not only has a high-efficiency air filtration function but also provides reliable anti-fall protection for the ceiling structure. With high filtration efficiency, adjustable air volume and multi-model design, this device can meet the different needs of clean rooms of various sizes. It is an essential supporting equipment for ensuring the structural safety and air cleanliness of high-standard clean rooms.

The device has a filtration efficiency of ≥99.95% for particles ≥0.3μm (tested by sodium flame method), which can effectively capture fine dust particles in the air and ensure the air quality of the clean room.
The stainless steel multi-angle nozzles with a wind speed of ≥20m/s can form a uniform air curtain, which not only purifies the air but also prevents dust from accumulating on the ceiling surface.
The device adopts a reinforced steel structure design, which can effectively bear the weight of the ceiling and prevent the ceiling from falling off due to external forces or long-term use.
The tunnel part is made of stainless steel sheet, which has high structural strength and corrosion resistance, ensuring the long-term stability of the anti-fall function.
We offer four models including AAS-1S-1200, AAS-1D-1500, AAS-1T-1500 and AAS-2D-2100, which are suitable for single-person single-blow, single-person double-blow, double-person double-blow and cargo blow scenarios respectively.
The interior trim can be customized with SUS304 stainless steel according to customer needs, further improving the corrosion resistance and cleanliness of the equipment.
