Chemical Fume Hood India, Fume Hood Manufacturers, Customized Chemical Fume Hood India

clean room equipments fume hoods


Fume Hoods are equipments that are used to ensure safety for the user as they won’t be exposed to too many hazardous and dangerous fumes. Fume Hood capture the fumes/effluents released during any given experiment, contain them in the enclosure and then emit through their well-designed exhaust system.

We specialize in standard Fume Hood and customized Chemical Fume Hood. Fume hoods typically protect only the user, and are most commonly used in laboratories where hazardous or noxious chemicals are released during testing, research, development or teaching. They are also used in industrial applications or other activities where hazardous or noxious vapors, gases or dusts are generated or released.

Fume-hoods draw air out of the rooms they are installed in. The fan sucks in the air toward the duct and exhaust outside

Testing Procedures of Containment

Fume hoods are specifically to decrease the loss of static pressure at a given baffle opening position. According to the standard procedures the average loss of static pressure at any given four points at ninety degree and 3 duct dia from the fume hood, that will not exceed 75 feet per minute at 0.25 inch, with full slash opening and face velocity of 100 feet per minute.

Fume hoods are developed and designed to be used as semiconductor ventilated enclosures so as to protect the user from harmful and toxic fumes and vapors and to eliminate the possibility of accidental fire which may lead to emission of inflammable gases during the course of experiments. Hence, the materials of fume hoods are carefully chosen between industrial grades fire resistant thick PCRC, pre coated corrosion resistant GI sheet. The work table is made of heavy gauge construction material fortified with acid proof glazed tiles/stainless steel grade ss-304 grade. The work bench is provided with a small made of stainless steel ss-304 grade. All modular fume hoods are provided with sliding sash made of special grade shatter proof glass duly framed in wooden/ aluminum frame with sliding motion and counter weight balanced mechanism.

Noise and Sound Levels

Our stainless steel ducts less fume hoods are designed with lower noise levels and the performance of these fume hoods are comparatively better than the industry standards of 60db, and approximately 15cm distance from the sash.

Illumination Levels at Work Space

Our versatile fume hoods make sure that a maximum of 800 lux light is available on the work table through diffuser fluorescent light arrangement.

Exhaust Assembly

these fume hoods are incorporated with an extremely durable and b exhaust system that generally persists a range of 500-1250 CM. These exhaust assembly comprises of balanced centrifugal impellers that are combined with a heavy duty three phase motor of Crompton greaves.

Exhaust Ducting

these fume hoods are also integrated with a FRP ducting of required dimension as per the requirements of the user.

Air Velocity

Our fume hood ensure that the optimum face velocity of 80 feet – 100 feet per minute is maintained with an accuracy of + 10 feet/minute with the sash in complete open position.

Volume of Exhaust:

Our fume hoods are capable of maintaining a constant exhaust volume. The maximum variation permissible due to baffle adjustment, in our in house test procedure is 6% of the given volume of exhaust.
