Key Benefits Of Ductless Fume Hoods

The U.S. holds over 45% of the global pharmaceutical market. Our dominance of scientific and medical fields has allowed us to raise the bar when it comes to the development and circulation of life-saving and life-changing medications. Before these medicines can be offered to the general public, however, they must undergo a grueling testing period; clean room standards must be met to ensure that they aren’t tainted or contaminated.

From GMP storage conditions to GMP quality control, there are a number of steps and tools that play a major role in this sterile environment.

Let’s take a look at some of the benefits that ductless fume hoods in particular offer.

Environmentally Friendly: Ductless fume hoods are designed to isolate and trap chemical vapors, thereby preventing their release into the outside environment. Because these chemicals can cause ecological harm, this type of fume hood is considered to be more environmentally friendly than others.

Versatile: There are many different kinds of fume hoods for many different applications. Ductless hoods each have their own filtration system based on their specific application; carbon filters are often used to capture vapors, organic solvents, acids, and even mercury and formaldehyde. For added air purity, HEPA filters can be installed.

Easy To Install: Ductless hoods are self-contained and don’t require venting to the outside. In fact, many units are portable and can be moved around with little difficulty — no filter changes necessary. The set up, operation, and filter maintenance of ductless fume hoods are all very straightforward and easy to comprehend.

Energy Efficient: When clean, filtered air is returned to the room, the need to move air in is eliminated. As a result, the facility’s HVAC system does not have to work as hard.

Cost Effective: As their name suggests, fume hoods don’t require ducts. This means that HVAC and construction costs can be completely eliminated from the equation.

Fume hoods are a necessary part of the laboratory environment. Ductless fume hoods provide several unique advantages that put them ahead of the ducted variety. As long as you’re fully committed to maintaining your clean room standards, however, either option will do the trick.

The Ultimate Guide To Ductless Downflow Workstations: Which One is Best?

A ductless fume hood is a device which recirculates filtered air from a hood or enclosure directly back into the working environment. These hoods are unique in that the contaminated air is not vented to the outside through a system of ducts, unlike conventional fume hoods. The objective of the filtration system is to reduce the levels of solids, gaseous or vapor constituent to that below the acceptable limit at the exhaust of the ductless fume hood.

Safety to laboratory personnel is provided by conventional ducted fume hood by drawing air across a front opening in the hood at a controlled rate, therefore preventing toxic vapours generated during the experiments from escaping into the general laboratory environment.

Air is then exhausted via a fan system to the outside of the laboratory, usually via an outlet mounted on the roof of the building. When released to the external atmosphere in this manner, chemical fumes and vapors, which would have otherwise been toxic in the enclosed environment of the laboratory, are diluted many times over and have an insignificant effect on the environment.

Ductless Downflow Workstations are high efficiency ductless fume hoods designed to protect the user and the environment from hazardous vapors generated on the work surface. Unrestricted front and side access facilitates applications requiring complex and intensive operator involvement, while downward airflow in the chamber protects the operator.

5 Types of Laboratory Fume Hoods and its Properties

A traditional laboratory fume hoods have a box with a movable sash window-like structure.  To ensure full protection, the fume hoods should be properly sited. Due to pedestrian flow, doors and supply air diffusers locate hoods to prevent crosscurrents at the hood nose. Sufficient laboratory supply air must be available to allow hoods to work at their required face velocities. The hood works by maintaining a fairly negative pressure within the hood to prevent any contaminant from escaping while at a constant pace drawing air through the hood opening. A suitable hood face velocity is of interest for the safe and efficient function of a laboratory fume hood. While excessive face velocities can often lead to friction and reduced containment, the hood's efficiency can also be compromised by insufficient speeds. Overall, the face velocity of a hood is recommended to vary between 0.3 m / s (60 fpm) and 0.5 m / s (100 fpm), but it is necessary to test the face velocity recommendation with local safety legislation before using the fume hoods. Most hoods are usually designed for a minimum face velocity at full sash opening; but as a means to save energy, some hoods design the hood's minimum face velocity at the half-sash opening, producing new low-flow laboratory fume hoods, which are now on market.

Although there is various type of Laboratory fume hoods,  5 of them are renowned among the user due to their different properties. Let’s have a look upon the same:

Bench-top Fume Hood - A fume hood at the bench-top is normally mounted on a bench-top or above a storage cabinet. Bench-top hoods are used for a wide variety of chemical procedures that require small to moderate quantities of low to high toxic materials. Benchtop Fume Hoods have efficient containment and emissions of low particulate mass gases, vapor, mists, fumes, and other aerosols. 

Distillation Fume Hood- A distillation hood is defined by a low height of the work desk, which results in the operator having a wide working height. It allows for the installation and positioning of large distillation equipment in the workroom. Otherwise, it has features similar to those of a regular fume hood. The hood is unable to withstand fires since the sash is fully sealed. If there is an explosion hazard, the user should have adequate strength to deflect or contain the anchored barriers, shields or enclosures.

Perchloric Acid Fume Hood- The perchloric acid reacts with organic materials violently. The perchloric fume hoods also require built-in water wash-down systems to prevent salt deposits from being perchlorinated. Both treatments use perchloric acid must be limited to a perchloric fume hood to avoid adverse interactions with certain chemical substances. Perchloric acid should not be used with a traditional fume hood. Perchloric acid vapours may settle to ductwork, resulting in perchlorate crystals being deposited. 

To Radioisotope Fume Hood- Radioisotope fume hoods are designed primarily to protect users from hazardous materials. We have specially designed workstations to withstand the weight of lead shielding tiles, and may also have lead-laced sashes. For decontamination purposes, the interiors are made of stainless steel with polished corners. 

Floor Mounted Fume Hood- For applications involving large Lab equipment, floor-mounted fume hoods are used. These hoods, as the name implies, are mounted on the floor, without any work surface. It allows the movement of materials and machinery into and out of the hood. Mounted floor hoods are often referred to as walk-in fume hoods, although incorrectly.

The amount of protection a fume hood offers can be affected by the way the fume hood is used. The 5 accurate ways to use Benchtop Fume Hood efficiently are bellowed: 

Distance is needed for safety- Ensure the exhaust works until work starts. Find out the obstructions on the baffles. When an airflow sensor is attached to the hood, check the status of the sensor. Even while operating, be alert to airflow shifts. Keep face outside the hood plane while using the fume hood. During hazardous work using the sash for partial safety. Work at least 6 back from the hood's nose. 

Equipment needed for protection- A line on the top of the bench is a successful recall. Using correct personal safety gear, such as gloves and splash goggles. This increases protection in the event of major spills, run-away reactions or explosions. Place the Lab equipment on blocks when using large machinery inside the hood, to allow air to flow under it when secure and practical.

How airflow destruction reduces the hood performance- Do not make fast movements in or out of the hood, use fans or instantly walk through the hood gap. This will result in airflow disruptions that reduce the hood's performance. Where possible, replace with less dangerous or less volatile chemicals. The hood should be kept closed, except during set-up of the apparatus or when working inside the hood is needed.

Where to keep sash- To optimize the efficiency of the hood keep the hood sash closed as much as possible. Keep the sash closed to optimize energy efficiency when not in use. If the output is suspected, or an airflow warning is activated, end-use and fully close the sash and do not remove sash or sash panels from the hood except when necessary for the set-up of appliances.

When it is needed when to remove or place sash or panel- Sometimes remove sash or panels in the hood before working. If flammable liquids or gases are present, do not place. There are no permanent electrical receptacles permitted within the hood and there is a risk of explosion, implosion or eruption, using an adequate barricade.
