What does the ventilation system consist of?

The ventilation system is generally composed of ventilation equipment, ventilation pipes, mufflers, fans and control systems.

1, commonly used ventilation equipment is mainly fume hood, atomic absorption hood, universal exhaust hood, desktop ventilation hood, etc. Fume hood is a safe treatment of harmful, toxic gases or steam ventilation equipment is used to capture, seal and transfer pollutants and harmful gases. Atomic absorption cover is mainly suitable for atomic absorption meter and other large precision instruments involving high temperature and need local ventilation. Universal exhaust hood can effectively protect the personal safety of laboratory staff. Table top ventilation hood is an essential equipment for the overall ventilation requirements of the laboratory.

2. For general ventilation pipes of ordinary buildings, if the gas discharged indoors is not corrosive, galvanized steel can be used for ventilation pipes. For laboratories that produce corrosive gases, PVC air ducts or GLASS fiber reinforced plastic air ducts should be used for corrosion resistant materials. In general laboratory ventilation engineering, PVC air duct is mostly used indoors and FIBERglass air duct is used outdoors.

3. For laboratories with large air ducts, square ducts are generally used to minimize the space occupied by ducts. Circular air duct is connected by plug-in, square air duct is connected by flange, plug-in can also be connected according to the actual situation.
