Fume Hoods

Ductless fume hoods mainly absorb and purify harmful gases during the experiment through an internal circulation double-layer filter (special adsorption material). The fume hood does not consume any indoor air, and the filtered air is returned to the room. The capacity reaches 1% of the TWA value (TWA value refers to the time-weighted average concentration of a chemical in the air usually in an 8-hour workday and a 40-hour workweek); at the same time, the exhausted air is monitored in real time, and the detection value is displayed on the LED screen. When the safety setting value is exceeded, an alarm will be issued. Ductless fume hoods do not require external pipes to discharge air into the atmosphere. Convenient to move and can be flexibly changed according to the laboratory layout. Ductless fume hoods can be installed and used immediately, reducing lengthy and expensive installation costs.
