Specification for construction of air disinfectant microbial negative pressure aerosol chamber

The air disinfectant microbial negative pressure aerosol chamber is used to test the sterilization performance of air disinfectants. The current epidemic situation is repeated, and there are many bacteria and viruses in the air. It is necessary to use air disinfectants for disinfection. Whether the disinfection performance of air disinfectants is good or not can be detected by using a microbial negative pressure aerosol chamber.

air disinfectant microbial negative pressure aerosol chamber requirements:
