In the laboratory, scientific researchers usually conduct experiments on the equipment operating table. Due to the diversity of experiments, which contain a lot of odor and harmful gases, ventilation and exhaust treatment are carried out on the laboratory equipment operating table to prevent It is very necessary to protect the personal health of laboratory personnel. At present, the ventilation and exhaust of the traditional fume hoods used in the laboratory need to be connected through pipes, and the exhaust gas collectors are collected and processed uniformly, which not only increases the complexity of the equipment, but also increases the difficulty of on-site construction and energy consumption.
The purpose of this utility model is to provide a ductless self-cleaning fume hood, which has a simple structure and is easy to install. It is used for small and medium-sized experiments and routine experimental operations in physics and chemistry laboratories. It is safe and reliable, simple and convenient to operate and install, and can purify the room, solve ventilation, exhaust, purification and protect the personal health of scientific researchers.
The ductless self-cleaning fume hood of the utility model comprises a working area component, one end of the working area component is openly arranged, and the working area component is provided with a working space; the open end of the working area component is provided with a filter component, the filter A cover assembly is provided outside the assembly: the filter assembly includes a primary filter layer disposed adjacent to the open end of the working area assembly, an activated carbon filter layer is provided on the other side of the primary filter layer, and a fan box assembly is provided on the other side of the activated carbon filter layer .
Xunling ductless fume hood series complies with the US SEFA standard and the Chinese industry standard JG/T385-2012. Xunling recirculating air fume hood is specially designed to protect the safety of laboratory personnel in experimental operations, which can prevent operators from inhaling some toxic, harmful, pathogenic or unknown toxic chemicals during experiments, and efficiently purifies and ventilates. The air in the cabinet and the laboratory provides safety protection for laboratory personnel.
1. The ductless fume hood does not need to install piping works, the installation is convenient, the exhaust gas is not discharged, and the new type is environmentally friendly.
2. The top can be equipped with a filter module system according to the experimental requirements to meet a variety of different experiments.
3. The advanced modular filtering technology can completely absorb the harmful gases, particulate dust and other substances produced by the filtering experiment.
4. There is no need to consume the energy consumption of air conditioners, saving energy efficiently.
5. It can be placed on the desktop or configured with a mobile wheel base, which is convenient and flexible, and is suitable for any complex experimental site.
1. Air inlet
Air can be drawn directly from the laboratory into the fume hood, creating negative pressure, and the steady face wind speed creates a natural barrier to isolate users and the chemicals they handle.
2. Comprehensive filtration system
The fan system sucks the toxic and harmful gases upward, and after filtering, returns clean air to the room. The excellent control concentration of the cabinet can ensure that the chemical gas in the cabinet will not return to the room and cause pollution.
3. Clean laboratory air
Different filters are configured according to different operations to effectively filter toxic and harmful gases, purify laboratory air, remove residual odors from chemicals, and improve laboratory cleanliness.
4. Purify the surrounding air
Continued filtration efficiency of ductless fume hoods can help purify indoor air
