Clean air balance safety weighing cover

Clean air type safety weighing coverworking principle：

1. Air inlet

Air can be directly drawn from the laboratory into the fume hood, creating negative pressure. The stable surface air velocity forms a natural barrier to isolate users from the chemicals they are handling.

2. Comprehensive filtration system

The fan system inhales toxic and harmful gases upwards, filters them, and returns clean air indoors. The excellent control concentration of the cabinet can ensure that the chemical gases inside the cabinet will not return indoors, causing pollution.

3. Clean laboratory air

Configure different filters according to different operations to effectively filter toxic and harmful gases, purify laboratory air, remove chemical residues and odors, and improve laboratory cleanliness levels.

4. Purifying the surrounding air

The continuous filtration efficiency of the fume hood can help purify indoor air.
