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
Conforms To ASHRAE-110-1995 (British Standard) Testing Method.
Construction Details:
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 S.S-316 grade/ M.S duly Powder Coated. The work table is made of heavy gauges SS-316. All our fume hoods are provided with sliding sash made out of special grade shatter proof temper glass duly framed in 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 (Heavy Duty 1/4 H.P A.C Motor ).
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.
Testing Procedures Of Containment:
Our fume hoods conforms to the performance test as per ASRAE-110-1995 British Standards of testing performance of chemical hoods.
They have a AM (As manufactured) rating of 0.05 ppm/4 LPM at fully opened sash.
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 pressure at any given four points at ninety degree angle and 3 duct dia from the fume hood will not exceed 75 feet perminute at 0.25 inch, with full sash opening and face velocity of 100 feetper minute.
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

The hood is fabricated from special grade pre coated mild steel sheet duly powder coated from outside and epoxy painted from inside. The inner walls of the working chamber is covered with epoxy coated asbestos or FRP or HDPE lining or as required. The working table is made of zet black granite and provided with gas/air petcocks and additional power points, diffused fluorescent tubes. The front shutter is of shatter proof clear glass, framed in suitable wooden structure with vertically sliding facility and is connected with counter weight balancing arrangement. Our Fume exhaust hoods are also available with full FRP construction or combination of FRP and Ply, with or without work bench. We also design and manufacture Scrubbers, Fume Extraction & Dust Collection Systems.
