The ventilation cabinet, also known as the cigarette cabinet or ventilation cabinet, is a large device in the laboratory, especially the chemical laboratory.The purpose is to reduce the contact between the experiments and the harmful gases.If you are completely isolated, you need to use a glove box.Ventures are first -level barriers to prevent toxic chemical smoke hazards.
The role of a vector cabinet
The first is the filtering of dust, that is, dust removal.The installation of activated carbon can be filtered out a lot of chemicals.Ammonia and carbon monoxide substances are not the same, they need special filters to remove.Compared with previous filtering materials, its use time is about 6 months, but the average activated carbon layer is generally 2 years. This is not absolute, but also depends on the use situation.

Venture Cabinet Operation Regulations
1. How to use 1. Press the control panel switch button.2. Open the lighting and fan switch.3. When using, pay attention not to pour the debris into the tank of the vector closet, so as not to cause the pipeline to block.4. After use, clean the ventilation cabinet in time.5. Turn off the lighting, fan switch.6. Turn off the power.
Blood cabinet principle
After the air is pulled away by the exhaust fan in the front of the cabinet, first filter the dust with foam plastic (about 6 months), and then filter with activated carbon (about 2 years of service life) to absorb a lot of chemicals, and then re -use it.The advantage is that it does not require external pipelines, does not pollute the external environment, and has a small impact on the temperature of the laboratory; the disadvantage is that the filtering material must be replaced regularly.It is very close to the experiments that cause noise.
Ventilation cabinet price
Hengan Brand Entry Venture Cabinet 7888 yuan This ventilation cabinet model is Y-XDT-120, the specifications are 1500*850*2350, the type is the landing type, the color is gray and porcelain white.The cabinet uses eight millimeters of PP board and PVC profiles. The performance is more stable, and it has good acid and alkali resistance and has a strong anti -curvature.Dongguan Jiahe Brabal House 6,300 yuan This vector cabinet can ensure the harmful gases in the cabinet, and some smoke and particles will not leak indoors, and it will not gather in the ventilated cabinet.Can cause explosion.It can also ensure that the staff will not be harmed in front of the ventilation cabinet in time.H. The material used by 8500 yuan for acid -alkali -resistant ventilation cabinets is made of PP. Therefore, such a vector cabinet and traditional ventilation cabinet have more advantages.The PP material has good acid and alkali resistance and corrosion resistance. Therefore, such a ventilation cabinet can be used under some high -concentric acid, and there will be no rust or yellowing and cracking.
