Fume Hood

PRODUCT DETAILS :
We are manufacturers of Fume hood, chemical fume hood in India since 1990. Our chemical bench fume hoods are indispensable and a pre-requisite in practically all chemical laboratories that handle toxins and hazardous chemical fumes and effluents. Our 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 models specifically designed to meet the challenging demands of various scientists for individual and specialized research applications. Over a short period of time Labard brand have been established as a reliable fume hoods exporters in India.
PRODUCT OVERVIEW :
Our chemical fume hoods are conceptualized and designed to provide a work area which is free from all the potentially hazardous fumes or chemical effluents that may be emitted during the course of a given experiment or procedure in a laboratory.
Our fume hoods capture the fumes released during an experiment by drawing fresh air from the environment, past the user into the unit.. This way the concentration of the chemical fumes/effluents are kept at the minimum possible levels in and around the breathing zone of the user. The vector of the air in the fume hood points to the inward direction and perpendicular to the face of the user. The velocity of the air is controlled at approximately 80 feet per minute, so as to control the particle kinetics of various aerosols and diffused gases.
Features :

• Ergonomic Design
• Energy Efficient Mechanism
• Low Noise Levels

CONSTRUCTION :
Our fume hoods are developed to be used as semi closed 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 be resulted due to the emission of inflammable gases during the course of a given experiment. Hence the material of construction of all our fume hoods are carefully chosen between industrial grade fire resistant commercial wooden boards covered with laminated sheets and lined completely with epoxy coating/FRP lining or corrosion resistant steel sheets having epoxy coating from inside, duly painted with attractive stove enamel/air drying spray paint.. The work table is made of heavy gauge construction material fortified with acid proof glazed tiles/ stainless steel grade ss-316. The work bench is provided with a small sink made of stainless steel grade ss-304. All our fume hoods are provided with sliding sash made out of special grade shatter proof glass duly framed in wooden/aluminum frame with sliding motion and counter weight balanced mechanism. Our units ensure minimum illumination level of approx 800 lux on the work table. The unit is equipped very diligent heavy duty exhaust system, comprising of dynamically balanced centrifugal impeller with high speed motor of approx 1440 RPM.
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.
Pressure (Static)
Our fume hoods are designed to minimize the loss of static pressure at a given baffle opening position. As per our standard procedures the average loss of static pretssure at any given four points at ninty degree angle and 3 duct dia from the fume hood will not exceed 75 feet per minute at 0.25 inch, with full sash opening and face velocity of 100 feet per minute.
NOISE/SOUND LEVELS :
Our fume hoods are designed to generate lower noise levels. The performance of our fume hoods are rated better than the industry standards of 60 db, at approximately 15 cm distance from the sash.
ILLUMINATION LEVELS AT WORK SPACE :
Our fume hood ensure that a minimum of 800 lux light is available on the work table through the diffuser fluorescent light arrangement.
EXHAUST ASSEMBLY :
Our fume hoods are provided with a very strong and high end exhaust system having a range of 500 – 1250 CFM (designed as per the size of the hood). The exhaust assembly consists of a dynamically balanced centrifugal impellers which are coupled with a heavy duty three phase motor.
