A Ducted Fume Hood is a type of ventilation system that primarily functions to provide personnel protection against toxic fumes, vapors, and dust. This containment device is connected to a ducting where contaminants pass before being exhausted into the environment. Its secondary function includes protection against chemical spills, runaway reactions, and fires by acting as a physical barrier.

The single, dual, tri-wall accounts for the ducted fume hood’s durability and capability to have service fixture on the external side walls of the fume hood. The more the number of walls and layers, the stronger the ducted fume hood is in terms of construction and ability to withstand chemicals.
EFH is the only single wall fume hood, that’s is why the base cabinet (EBC) is required since the worktop and service fixtures are connected there.

Chemicals can be stored during an ongoing analysis but ducted fume hoods are not designed for permanent chemical storage. Items placed inside the fume hood can interfere with air flow and may cause contaminants to be drawn in.
Base cabinets are the appropriate chemical storage. Esco offers a wide range of storage solutions for general purposes, corrosive, and flammable substances.

Chemicals are exhausted out into the atmosphere untreated so fume hoods are inappropriate for waste disposal. Always follow proper chemical waste disposal protocols designated in your laboratory.
Face velocity is the measurement of speed at which air enters the ducted fume hood's opening. Face Velocity measurement is one of the tests recommended by ASHRAE 110 to check whether a fume hood is effective in containing chemical fumes. per ASHRAE 110, a properly working ducted fume hood should have a face velocity between 0.30-0.60 m/s.
The ASHRAE 110-2016 standard is a comprehensive method for evaluating the operator safety of fume hoods by determining quantitatively and repeatably how well the fume hood contains vapors released in the workzone. This American standard has three parts:
a. Airflow Visualization - Local and gross airflow visualization tests conducted to observe airflow patterns inside work chamber
b. Face Velocity Measurements - Face velocity and uniformity tested at 100% and design sash opening position
c. Tracer Gas Containment - uses Sulfur hexafluoride to test if there are leakage across the fume hood.

EN 14175 is a harmonized European standard which supercedes the former national standards of Germany, the UK and France. A key element of the EN 14175, which is not present in the American ASHRAE 110 standard, is the robustness test, which simulates airflow disturbance in front of the hood.
a. Location
Location impacts the nature and extent of external airflow disturbances which may affect a ducted fume hood's performance. It is advisable to have a site assessment before purchasing a ducted fume hood.
b. Application
The types of chemicals, quantity, temperature and nature of handling are important factors to consider. There is a wide range of ducted fume hood models, each designed to handle a specific type of chemical and application.

a. Sash Stop
This safety feature limits sash movement beyond 457 mm (18") to encourage users to work at safe levels. When raised above said height, the sash will automatically and gently fall back to safe levels through Esco's Creep Down Mechanism. This feature can only be disabled by a key, which permits Laboratory Managers or Safety Officers to restrict hood operation.
b. Airflow Monitor
Esco's Sentinel XL Airflow monitor alarm is an optional accessory that accurately monitors facev elocity and generates an alarm when inflow decreases to unsafe levels. This also has a sash alarm that activates when the sash is not in the recommended height level.
