subject: Canopy Chemical Hoods Manufacturers From India [print this page] Weiber Canopy Chemical Hoods are primarily used to exhaust non-toxic materials such as steam, odors and heat. Canopies are crafted with an integrally welded construction, fixed baffle and are available in either wall or island configurations. Several features can be added to meet users specific needs. Depending on customers requirements, canopies are available in stainless steel or powder coated steel. These containment devices have different modes of operation and different uses. Weiber can also avail customized canopy fume hood according to users requirement.
Weiber is a leader in the design, manufacturing and installation of Laboratory Fume Hoods. Fume hoods typically protect only the user, and are most commonly used in laboratories where hazardous or noxious chemicals are released during testing, research, development or teaching. They are also used in industrial applications or other activities where hazardous or noxious vapors, gases or dusts are generated or released. Weiber most canopy fume hoods are designed to connect to exhaust systems that expel the air directly to the exterior of a building, large quantities of energy are required to run fans that exhaust the air, and to heat, cool, filter, control and move the air that will replace the air exhausted. Weiber fume hood and ventilation system design focuses on reducing the energy used to operate fume hoods and their supporting ventilation systems.
The ultimate goal of chemical hood use is to contain the contaminants generated within the hood. The chemical hood removes particulates and aerosols, not gases and vapors. It provides biological protection for both specimen and user. Chemical hood offers three general types of uses: General Purpose, Radioisotope, and Perchloric Acid. Hoods approved for each of these uses will appear similar but require different functional and operating parameters. A tissue culture hood is designed to protect biological specimens by bathing the work area with a laminar flow of air free from particulate contamination. Because these devices force air out across the work surface and toward the worker they protect only the specimen, not the user. Air is passed down from the top of the hood and across the work surface, and is exhausted or re-circulated without entering a worker's breathing zone. This filtration system only removes particulates and aerosols. Because all clean benches and most biological safety cabinets exhaust air back into the work area, they cannot safely be used with hazardous gases and vapors. Canopy fume hood are specifically designed to vent non-toxic materials such as heat, steam and odors from large or bulky apparatus.
