Medical Aerosol Absorber is developed according to the worsening hospital environment. It can be easily realized that polluted air away from medical personnel and the sick in particular space within short time. So it can be widely applied in medical institutions to protect medical staff and patients' health. Air Filtration System is the main guarantee equipment performance of the system. It consists of filter, air blower, air duct and air purifier. The primary function of Air filtration system is to purify the outer space air through the air filter and air purification filters constantly , then put back in the air, air filtration system can ensure the cleanliness classes at air outlet where at the center of the main filter, long for 450mm, wide for 305mm, 550mm critical plane distance range from the filter downstream surface reach Class 100.
