Lab Fume Hoods Supplier Malaysia is a laboratory furniture that has a box-like structure with one side open or partially open. The function of the fume hood is to reduce and remove harmful gasses, dust, mist, and aerosols resulting from the use of chemicals in the fume hood so that they do not accumulate in the room or laboratory. In addition, the fume hood also functions as a physical barrier between chemical reactions and fume hood users, protection against inhalation of harmful gasses, chemical spills, and protection against fire.
Lab Fume Hoods Supplier Malaysia Working Principle
The fume hood operates on the principle of drawing all gasses, dust, mist, and aerosols produced by chemical use to be absorbed by the filter and then released by the blower. The fume hood will maintain a relatively negative pressure to prevent contaminants from escaping while drawing air in at a consistent rate through the fume hood openings. The rate at which air is drawn into the fume hood is critical to its safe and effective operation. The air intake speed should be between 0.3 m/s (60 fpm) and 0.5 m/s. The gasses released by the blower will be diluted many times in the atmosphere, having no effect on the environment.
Types of Lab Fume Hoods Supplier Malaysia
There are 2 types of fume hoods, namely Ducted fume hoods and Ductless fume hoods. Ducted fume hood is a type of fume hood that is widely used in laboratories, this type of fume hood can be directly installed in the laboratory room by perforating the laboratory wall for the installation of ducting (exhaust air ducts) and scrubbers. Meanwhile, Ductless fume hood is a type of portable fume hood that is equipped with a filter, because it does not have ducting so that this type of fume hood can be easily moved as needed.
What Are Their Benefits?
This Fume Hood includes locally made ventilation equipment. Designed to reduce exposure to toxic fumes, harmful gases and dust. Generally, it is equipment for laboratories with large sizes complete with a cabinet at the bottom which is used as a table or holder.
While local ventilation equipment itself is quite a lot, ranging from biosafety cabinets, inoculation boxes and clean air cabinets. The equipment includes a hazardous air influence control device. Good for:
- Workers or Personnel
- Research materials
- Laboratory equipment
This cupboard serves as a protection for personnel or workers from toxic gases that are dangerous and possibly inhaled during research, testing and learning processes in the laboratory. On the work table or counter top there are Phenolic Resin, Stainless Steel Sus 316 and Epoxy Resin. Fume hoods handle hazardous chemicals so air is drawn away from laboratory workers starting at the face of the equipment, across work surfaces and through air ducts where it is then released into the atmosphere. Proper, uninterrupted airflow is essential in a fume hood; do not store large equipment in it or do anything that may interfere with the movement of air inside the unit.
