Fume Hood Exhaust System Manufacturers Delhi

A fume hood exhaust system is a crucial component of laboratory safety infrastructure, designed to protect personnel and the environment from hazardous fumes, vapors, and particulates generated during various laboratory procedures. Here’s a breakdown of its key components and functions:

1. Fume Hood: The fume hood is the enclosure where laboratory work is conducted. It is typically constructed of durable materials such as steel, glass, or plastic and features a transparent sash or door that can be raised or lowered to control airflow and access to the interior workspace. Fume hoods come in various configurations, including bench-mounted, walk-in, or canopy-style hoods.
2. Work Surface: Inside the fume hood, there is a work surface where laboratory experiments and procedures are performed. This surface is resistant to chemical spills and easy to clean to prevent contamination.
3. Sash: The sash is a movable barrier located at the front of the fume hood that can be raised or lowered to control airflow and access to the workspace. When the sash is lowered, it helps contain fumes and prevents them from escaping into the laboratory environment.
4. Airflow Control: The fume hood exhaust system relies on a combination of airflow to capture and remove hazardous fumes. Typically, a blower or fan located in the system’s ductwork creates negative pressure within the fume hood, drawing air and contaminants away from the workspace and expelling them outside the building through an exhaust stack.
5. Ductwork: The ductwork connects the fume hood to the exhaust fan and exhaust stack, providing a pathway for contaminated air to be safely expelled from the laboratory space. The ductwork is typically constructed of corrosion-resistant materials and designed to minimize resistance to airflow.
6. Exhaust Fan: The exhaust fan is a critical component of the fume hood exhaust system, responsible for creating the necessary airflow to capture and remove hazardous fumes from the fume hood. It is usually located outside the laboratory building to prevent re-circulation of contaminated air.
7. Exhaust Stack: The exhaust stack is the final component of the fume hood exhaust system, responsible for releasing the contaminated air into the atmosphere at a safe height above the building to prevent re-entry into the ventilation system.
8. Safety Features: Modern fume hood exhaust systems may include safety features such as airflow monitors, alarms, and automatic sash closers to ensure compliance with safety standards and protocols.
