A Fume Hood (Fume Cupboards) is a type of local exhaust ventilation system inside the laboratory. It is a typical enclosed cabinet except front face. The front opening will be equipped with a moving sash made out of toughened / safety glass. Air is drawn in to the hood under, through the opened sash and is exhausted through openings in the rear & top of the cabinet to a remote point such as an exhaust stack on the roof of the building.
Chemical fume hoods, when used properly are one of the most reliable engineering controls in the Laboratory. They protect the users by:
Containing vapors, dusts, gases, fumes etc. generated within the hood, and removing them as airflows in to the hood and then out via the laboratory exhaust systems.
Contributing to laboratory ventilation as air flows through the hood.
Shielding the user with a clear sliding window called sash, that controls aerosols and prevent injury from splashes, fires or minor explosions that may occur inside the cupboard.
PURPOSE of Fume cupboard in Laboratory
Laboratory fume hoods are one of the most important equipment’s used to protect laboratory personnel from exposure to toxic gases, hazardous chemicals fumes and harmful vapors generated during experiments inside the fume hoods.
Function
A laboratory fume hood is equipped with a baffle designed to control air flow patterns within the enclosure and manage an even distribution of air at the opening. When connected to properly designed exhaust system, the fume hood will carry the undesirable effluents -generated within the enclosure during a laboratory procedure- away from laboratory personnel. When used properly, they can provide an effective backup safety device for the containment and exhaust of toxic, offensive or flammable materials.
STANDARD FUME HOOD SPECIFICATION
FIRE SUPPRESSION SYSTEMS
Pre-engineered fire suppression system with gas fire protection for fume cabinets using CO2 extinguishing agent.
Fast and effective individual fume hood fire protection and fume cabinet fire suppression
The automatic fire detection and automatic fire
Extinguishing system installs directly inside fume chamber and exhaust hood – closer to where a fire can start.
System use linear detection tubing which is installed throughout the risk area and connected to the cylinder valve.
A complete, ready-to-install automatic fire suppression system includes: cylinder, differential pressure valve, discharge tubing and nozzles, manual actuator, connectors and mounting brackets
Available in 5 Kg and 10 Kg sizes
AUXILIARY AIR SUPPLY SYSTEMS
Auxiliary air supply units are intended for use when it is not feasible to introduce the required makeup air through the room ventilation systems.
An additional supply air plenum on the top, front portion of the hood supplies the required make-up air directly onto the face of fume hood via its own blower and ducting. Auxiliary air supply volume can be made equal to the Exhaust air – therefore there is no air required from the laboratory space.
Auxiliary air is being brought from outside area and it has been filtered thru a Sand louver and Blue fiber filters. The blower speed can be regulated with rotary speed regulator.
Diffusers are with volume and air direction adjustable louvers.
This system is not recommended during extreme hot and humid ambient conditions.
The advantage of an auxiliary air supply to fume hood is that up to 70% of the air required for the station can be pulled in and utilized from the outside. By using unconditioned, outside air, energy consumption is effectively minimized.
