Product Description

Product Description

In laboratories, fume cupboards are the primary method of controlling exposure to toxic, offensive or flammable vapours, gases and aerosols. A type of local exhaust ventilation system, fume cupboards typically consist of a cabinet, or hood, with a moveable front sash or window, made out of safety glass.

They rely on extraction, which is sometimes controlled by the building's air conditioning and heating system; fumes are drawn into the hood and expelled through a neutralisation filter. In order to keep protection levels high, fume cupboards have to be used effectively and maintained appropriately. Therefore, the airflow within the fume cupboard needs to be enough to control the airborne contaminants effectively, with factors such as design, size of the window opening, type of process and the substance(s) being controlled all affecting the airflow of the cupboard.

The main purpose of installing a fume hood in a laboratory is safety. It's that simple. The better the fume hood, the safer the employee and when it comes to toxic chemicals and tracer gases, you can't be too careful. Because the safety standard is so high for labs, it's not only critical to have your fume hood testing annually, it's also illegal not to.

The chemical fume hoods are total exhaust system require ductwork. They are available with and without bottom work surface and in variety of sizes from 24" to 96" length. The single walled construction provides maximum work space. External lighting make it explosion & spark proof unless it equipped with blower module. (Blower is optional, is not explosion proof nor rated for acid and corrosive chemicals).

    More About the Fume Hood

    Laboratory fume hoods are a type of ventilation system with the primary function to exhaust chemical fumes, vapors, gasses, dust, mist and aerosol. Fume hoods also serve as physical barriers between reactions and the laboratory, offering a measure of protection against inhalation exposure, chemical spills, run-away reactions and fires.

    A typical fume hood has a box like structure with a moveable sash window. Experimental procedures are performed within the hood which is consistently and safely ventilated, usually by means of an extract blower and ductwork. Chemical fumes are exhausted and diluted many times over in the atmosphere and have a negligible effect on human health. When environment concerns are of importance, an extract treatment system, often referred to as a scrubber is installed to remove most of the vapors from the exhaust air stream.

    The hood functions by maintaining a relatively negative pressure in the interior of the hood to prevent any contaminant from escaping while drawing air in through the hood opening at a consistent rate. A suitable hood face velocity (the speed at which air is drawn into the hood) is of importance to the safe and effective operation of a fume hood. While excessive face velocities can often result in turbulence and reduce containment, insufficient velocities can also compromise hood performance.

    In general, a hood's face velocity is recommended to be between 0.3 m/s (60 fpm) and 0.5 m/s (100 fpm), however it is important to check with local safety regulations on the face velocity recommendation before using the fume hoods. Most hoods are commonly sized for a minimum face velocity at full sash opening; but as means to conserve energy some hoods size the minimum face velocity of the hood at half-sash opening creating new low flow fume hoods, which are now present in the market.

    Fume Hood Maintenance

    Hoods should be evaluated by the user before each use to ensure adequate face velocities and the absence of excessive turbulence.

    • In case of exhaust system failure while using a hood, shut off all services and accessories and lower the sash completely. Leave the area immediately.

     Fume  hoods should  be certified, at  least annually, to ensure they are operating safely. Typical tests include face velocity measurements, smoke tests and tracer gas containment. Tracer gas containment tests are especially crucial, as studies  have shown that face velocity is not a good predictor of fume hood leakage.

    • Laboratory fume hoods are one of the most important used and abused hazard control devices. We should understand that the combined use of safety glasses, protective gloves, laboratory smocks, good safety practices, and laboratory fume hoods are very important elements in protecting us from a potentially hazardous exposure.

     Laboratory fume hoods only protect users when they are used properly and are working correctly. A fume hood is designed to protect the user and room occupants from  exposure to vapors,  aerosols, toxic  materials,  odorous,  and  other  harmful substances. A secondary purpose is to serve as a protective shield when working with potentially explosive or highly reactive materials. This is accomplished by lowering the hood sash.
    FAQ

    Why do fume hoods use so much energy?
    It's the air being sucked through the fume hood, not the fume hood itself that consumes so much energy. For health and safety reasons, labs use 100% outside air which must be heated or cooled for comfort before it is brought into the lab. In addition to the energy required to condition the air, a significant amount of additional electricity is required to run large fans to move the air through the building and through the fume hoods.

    How does shutting the sash save energy?
    Most fume hoods at Stanford are variable air volume (VAV), meaning that the fume hoods are designed to vary the air flow based on how wide open the sash height is. Sash position is connected to the building's ventilation system so that a building's fan speed and the volume of air moved is reduced when the sash is lowered.

    Is it safe to shut the sash?
    The sash is an important safety barrier between the fume hood interior and the laboratory, protecting the lab user. Sashes should be opened only to set up or modify an experiment. At all other times, shutting the sash is safest. When the sash is shut there is still some air flow through the hood to remove any fumes.

    How do I remind myself and my roommates to close the sash?
    You can post a sticker, like the one shown in the picture below, to remind yourself and your lab mates to close the sash when not in use. The sticker also educates new fume hood users tha a lower sash is safer, and that the sash should only be open when setting up and modifying experiments.

    What other fume hood practices can reduce my energy consumption?
    • Never use a fume hood just for storing chemicals - they belong in a safety cabinet, which doesn't require huge volumes of air.
    • If your fume hood has an occupancy switch, turn it off when not in use.
    • If your group is no longer using a specific fume hood, consider having it locked and de-commissioned so air no longer flows through it.
