Prevention from Harmful gases in Laboratories

Ducted Fume Hoods are used to do experiments with potential dangerous fumes, vapors, and chemical powders. Ducted Fume Hoods are ventilated enclosures to carry on experiments on fumes and vapors. These type ventilators are used in laboratories for fume extraction and exterior exhaust. These types of ventilators are applied in the cases of dealing with high volume of volatile organics and heavy powder.

Features of Ducted Fume Hoods:

The standard features of Ducted Fume Hoods are:
  • Wall and sash material available in clear Polycarbonate, clear static Dissipative PVC, and Clear PVC.
  • The Polypropylene work surface of the Fume Hoods restricts the other acids and chemicals not to damage the work surface.
  • For static Dissipative Fume Hoods, optional stainless steel work surface was allotted at grounds terminal.
  • These Ducted Fume Hoods are easily movable, modular, and economic system.
  • The top panel of this Ducted Fume Hoods is so clear to produce sufficient light in the work area.
  • The air flow will be restricted by two hinged access shield.
Options for the Ducted Fume Hoods:

Two different OD duct ports are available either 6’ or 8’ OD duct port. Optional Fan Module will be available which is easily operated to adjust the speed. External Fluorescent Light also available for a clear clarity working area. Airflow alarm will be provided to know the velocities of the air within the fume hood.

Specifications of Ducted Fume Hoods:

The main specifications of Ducted Fume Hoods are the well constructed-wall with clear Polycarbonate and clear static Dissipative PVC. The work surface of the Fume hoods is chemical resistant with white polypropylene fume hood to resist the acids and other chemicals.

The Fan motor of the Ducted Fume Hoods is adjustable and permanently lubricate. The Fan motor will be protected by automatic reset thermal overload protection. The fan motor will be covered by Polypropylene or Stainless Steel. The average airflow velocity is 90 feet per minute and the sound level was less than 68 decibels.

Benefits of Ducted Fume Hoods:


There are many benefits with this Ducted Fume Hoods.
  • Environmental benefits. By this fume hoods can trap the harmful and dangerous vapors not to mix in the environment. With the help of Fume hoods, the environment will be free from the harmful gases.
  • This type of Fume hoods are so safe to people because of cabinet airflow and face velocity protects the users from accidental exposures to fumes.
  • Energy will be used efficiently with this Fume Hoods. Because of filtered air return into the room. There will be no need of HVAC capacity to make up air.
  • The cost will be also decreased by using Fume Hoods. By installing Ducted Fume Hoods HVAC, ductwork facility, and construction costs will be curbed down.
These are the benefits of installing Ducted Fume Hoods in Laboratories. 

Conclusion:

Ducted Fume Hoods are very useful ventilators in Laboratories for storing and filtering harmful gases during experiments. There are some benefits also with this Fume Hoods like the environmental conversation.
