The ducted fume hood is a critical local exhaust ventilation device used to protect laboratory personnel from exposure to hazardous fumes, vapours, and airborne particles generated during laboratory procedures. The system operates through a ventilated enclosure fitted with a movable sash and internal baffles that capture contaminants and channel them safely out of the building via a dedicated PVC duct line. The duct work runs from the fume hood to the rooftop discharge point, ensuring that hazardous substances are expelled at a safe distance from occupied areas.

This system is supplied and installed in accordance with the requirements of the Department of Environment (DOE), including the Pemberitahuan Bertulis approval process. DOE approval confirms that the ducting system and all associated air protection components along the duct line comply fully with the guidelines and requirements set by the DOE authority. This certification is essential for laboratories operating under Malaysian environmental regulations and demonstrates a commitment to responsible laboratory ventilation management.
