The negative-pressure fume cabinet creates a controlled suction environment that draws air from outside into the cabinet, thereby preventing the spread of toxic or hazardous substances and protecting laboratory personnel. Air enters through the front opening, travels across the work area to capture fumes, smoke, and particulates, and then exhausts through the top outlet. Furthermore, the cabinet optionally integrates high-efficiency filters to remove harmful gases and microorganisms, so the discharged air meets environmental safety requirements. Therefore, the system enhances both operator safety and facility compliance.
