Product Description

Product Description

A device enclosed except for necessary exhaust purposes on three sides and top and bottom, designed to draw air inward by means of mechanical ventilation, operated with insertion of only the hands and arms of the user, and used to control exposure to hazardous substances. These devices are also known as laboratory fume hoods.

Chemical fume hoods, when used properly, are one of the most reliable engineering controls in the laboratory. They protect workers by:

• Containing vapors, dusts, gases, and fumes generated within the hood, and removing them as air flows into the hood and then out via the laboratory exhaust system
• Contributing to laboratory ventilation as air flows through the hood
• Shielding the worker with a clear sliding window, called a sash, that contains aerosols and prevents injury from splashes, fires, or minor explosions that may occur inside the hood

Our Advantages

• Engineered to exhaust 50% less conditioned air from the laboratory
• Designed to capture fumes while working in today's modern laboratories with varying factors such as lab traffic, fluctuating temperatures and interior hood loading
• Fume capture and containment can be demonstrated with tracer gas testing
• Low airflow provides an ideal environment for working with powders and delicate work

Application Cases

A fume hood is a ventilated enclosure used to control exposure to hazardous or odorous chemicals. An exhaust fan draws air into the front opening of the hood, then up and out of the hood through the ductwork. Because the air that is pulled into the hood is not filtered, fume hoods only offer protection to its users and no protection to the products inside the hood.

Hood performance and efficiency depends on an adequate and uniform velocity of air moving through the sash opening. Hood performance is adversely affected by many factors including mechanical malfunction, drafts or open doors and windows, and poor operating procedures of the person using the hood.
