It helps in keeping the people from the cleanroom free from any kind of harmful gas that might affect their health.


A  fume hood is one of the best instruments or equipment that is used to keep the entire cleanroom or laboratory clean. It used by many laboratories around the world. It is one of the popular ways of keeping your environment around the cleanroom safe and secure.
