Fume Hood is an enclosure which is used to remove fumes and air borne particles at the contamination source. It is a kind of fume ventilation system which prime work is to remove smoke, dust mist and chemical fumes and restrict their entry into laboratory environment. A laboratory fume hood comprises of metallic sheet enclosure, steel or marble stone work bench, service fixture and electrical points. For fume exhaust, heavy duty blowers are fitted and remotely connected to the duct. Chemical fume hood, fume cupboard and fume closet are similar names of fume hood.
Fume Hood Applications
The core application of a fume hood is fume removal also minimizing nuisance odors. It is used in laboratory where some important tasks are preformed such as solvent mixing, soldering and working with volatile organics, powder and flammable chemicals, different types of acids and low odor thresholds etc. and all these tasks generate hazardous fumes that are harmful not only environment but also for operator and surrounding people. In this case a fume hood becomes important which sucks fumes and throws outside the working environment to maintain acceptable air quality aiming for enhancing safety of personnel as well as laboratory environment.
We are fume hood manufacturers in India. Our fume hood systems meet ASHRAE standards and can withstand any type of acid exposure. Standard units are made in 2ft, 4ft, 5ft, 6ft and 8ft width with variety of construction options. We also design laboratory fume hoods for Hydrofluoric and Perchloric acids at economical price in India.
Inner working chamber or area is the most important part of fume hood which remains in direct contact of fumes, acids and different types of chemicals. We make inner chamber walls of stainless steel (304 / 316) which is further coated with FRP layer if needed. The standard sizes of chamber are 2ft, 3ft, 4ft, 5ft, 6ft and 8ft etc.
The work bench of fume hood is either made of Stainless steel (grade 316) sheet or granite marble. If need it is also coated with FRP layer for double protection.
External surface is either made of powder coated GI sheet or stainless steel sheet. At the time of asking for discussion, customer has to confirm the material of construction to get precise price quotation.
Service valves are optional accessories; at added cost we can fit wet and dry service valves (brass needle valves) for raw water, nitrogen gas, air and vacuum.
To run the apparatus inside fume hood, we fit electrical sockets 2, 4 or 6 as required.
It is a glass window mechanism which is moved up and down using sash track. Sash track is a system made of weights and a pulley. Operator can easily move sash up or down and keep at desired height during work.
For suction in fume hood we provide centrifugal blower assemble made of direct drive motor of any branded make.
Chemical storage cabinet
At the bottom of fume hood we provide ventilated cabinet to store chemicals.
If you want to buy fume hood for specific application or to use oversize apparatus in it, we can design the exact unit fitted with all useful accessories.
Our fume hoods can easily pass any required quality certifications such as ASHRAE110 - 1995 and EN-14175- 2003, if you need such certificates, we can provide you third party test certificates at extra cost.
