About Fume Hoods

Certified by Godrej Aeolus, these extractor hoods have very high containment characteristics comparable to those of the world's leading manufacturers, ensuring that end users have a high degree of protection. Aeolus is designed with great attention to detail.

Aeolus is simply the unbeatable option in extractor hoods taking into account the following parameters


An extraction hood provides safe ventilation to protect against exposure to hazardous or toxic fumes, vapors, or airborne particles. A chemical extraction hood is primarily used in laboratory and manufacturing applications to protect the user or the environment outside the hood, but it can also be used to protect materials or experiment under the hood. Ducted extractor hood designs connect to a remote exhaust system to safely ventilate the building's exterior. Ductless extractor hood configurations filter and recirculate purified air through an integrated fan and filtration system.


Laboratory extraction hood add-ons include activated carbon filters to remove non-hazardous nuisance odors. HEPA or ULPA filters can also be added to a light-duty fume hood to remove microscopic dust and microbes. Explosion-proof extractor hood configurations are available for volatile or combustible applications. A wall-mounted canopy extractor hood provides additional flexibility when floor space is limited.

Types Of Fume Hoods

Ductless smoke extraction hoods: portable

Carbon filter and HEPA enclosures, also known as filter extraction hoods, are ductless laboratory enclosures that remove fumes, vapors, and hazardous particles from the laboratory. No installation costs as no ducts are required. These ductless containment hoods are available in widths of 24", 32", 48", 60", 72" and 96". They can be used for the removal of chemical fumes, dust and particles, handling of pharmaceutical powders, control of solvent or acid vapors.

Ducted Fume Hoods - High Clearance

Cleatech's high-clearance construction laboratory extraction hoods (often referred to as ducted extraction hoods or chemical fume extraction hoods) are available from 18" to 72" wide, including the chemical spill tray/polypropylene work surface, ideal for applications that require exterior exhaust ducts and need complete visibility of the interior fumes of the hood. These extraction hoods can be ordered with up to two optional fan modules with adjustable air speed. Ducted extraction hoods are ideal for welding or chemical processing that requires the removal of potentially hazardous fumes with low-level corrosive vapors. Material available in polycarbonate, non-dissipative PVC and ESD PVC construction

Ducted Fume Hoods - Polypropylene


Cleatech's durable, chemical-resistant construction cleatech laboratory polypropylene extraction hoods are a turnkey ventilation system designed for applications that require exterior exhaust ducts. These chemical extraction hoods are bottomless and can be placed on standard-sized work tables. A permanent background/work surface can be added upon request. These laboratory extraction hoods can be equipped with a fan module, they are an excellent choice for chemical processing that requires the removal of potentially hazardous fumes.

Ducted Fume Hoods-Stainless Steel

Stainless steel extraction hoods have good resistance to a wide range of chemicals and excellent resistance to moisture and heat. They can be easily decontaminated and cleaned and are ESD-grade suitable for static electricity-sensitive applications if your body is connected to the building's ground. The sheet is made of PVC static heatsink and the work surface is optional and removable. These laboratory hoods can be ordered with or without exhaust ventilation unit. It works primarily to provide protection to personnel against toxic fumes, vapors, and dust, but is not compatible with some acids.

Containment Ventilated Enclosures (CVE)

Ventilated containment enclosures, also known as a HEPA filter extractor hood or dust containment hood, comply with dust handling, such as the preparation of non-sterile hazardous drug compounds in pharmacies. They can be used to protect the user from particles while weighing, mixing, preparing, composed, dispensing, administering HD or hazardous low- to moderate-risk powders.

Ducted Fume Hoods - Vertical Sash

High efficiency coated steel benchtop fume hood with chain driven vertical sash system. Ideal for general chemistry applications. Chemical resistant liners to protect the interior of the fume hood against damage from any chemicals. Available with flammable and acid storage base cabinets and many other accessories such as Automatic sash closing option. Fume hoods are available in three standard lengths, 48” 60″ and 72” and two standard internal depth 24” and 30.

How a Fume Hood Works

An extractor hood is a ventilated enclosure in which gases, vapors and fumes are contained. An extractor located at the top of the laboratory building extracts the air and airborne contaminants through the connected ducts and expels them into the atmosphere.


The typical extraction hood found in Princeton University laboratories is equipped with a movable front blade and an inner deflector. Depending on its design, the blade can move vertically, horizontally or a combination of the two and provides some protection to the bell user by acting as a barrier between the worker and the experiment.


Slots and deflectors direct the air that is expelled. In many hoods, they can be adjusted to allow for the most uniform flow. It is important that the deflectors are not closed or blocked, as this blocks the escape route.


The airfoil or beveled frame around the hood face allows more even airflow into the hood by avoiding sharp curves that can create turbulence.

how fume hood works diagram

There are basically two types of fume hoods at Princeton, they are:


Constant volume – 


where the exhaust flow or the amount of air extracted through the hood is constant. Therefore, when the blade is lowered and the cross-sectional area of the bonnet opening decreases, the speed of airflow (front speed) through the bonnet increases proportionally. Therefore, higher front speeds can be obtained by lowering the blade.


Variable air volume (VAV) - 

Where the exhaust flowrate or quantity of air pulled through the hood varies as the sash is adjusted in order to maintain a set face velocity. Therefore, when the sash is lowered and the cross-sectional area of the hood opening decreases, the velocity of airflow (face velocity) through the hood stays the same while less total air volume is exhausted.

Best Covid-19 Protection Face Masks And Face Shields

Image
  How Do The Different Types Of Face Masks Work? Medical masks: Also called surgical masks, they are loose disposable masks. They are intended to protect the user from contact with droplets and aerosols that may contain germs. A medical mask also filters large particles into the air when the wearer inhales. To make medical masks better fit the shape, knot the earmuffs where they attach to the mask. Then bend and tuck the unnecessary material under the edges.. N95 masks: An N95 mask is a type of respirator. It offers more protection than a medical mask because it filters out large and small particles when the wearer inhales. The general public can use non-surgical N95s when supplies are available. Health care providers must be trained and pass an adjustment test before wearing an N95 surgical mask. Like surgical masks, N95 masks are meant to be disposable. However, researchers are testing ways to disinfect and reuse them. Some N95 masks, and even some cloth masks, have valves that ...

PBC Medical Products And Equipment Under One Roof

  Different Types Of PBC Products And Equipment For Your Medical And Healthcare Needs ClickZip syringe:  ClickZip injection consists of a completely unique retractable needle technology. The syringe includes a unique needle attachment and piston system. Once the piston is completely pressed, the piston mechanism is locked with the needle unit. When the piston is pulled back, the needle is pulled into the syringe barrel, and mechanically tilts to at least one side. As a consequence, the piston can then be cut, resulting in a stand-on unit that encapsulates the needle used, thereby defending others from unintentional needle sticks and stopping the syringe from being reused. Nitrile gloves: Disposable nitrile gloves are made in a laboratory, not like latex, so manufacturing issues aren't so worrisome. As an alternative to latex, nitrile is now the preferred choice of scientific and commercial protective gloves as an alternative to latex when allergy is a concern. Nitrile gloves ...
