Which induced draft fan should be chosen for an environment with acidic flammable gases?
Thread Content
Does anyone among you know which type of exhaust fan should be used when the working environment contains flammable gases, with the medium being mainly acidic gas mixtures?
It’s better to choose a water ring pump; it’s safer, and a gas-liquid separator can be added later.
Choose an explosion-proof motor for the exhaust fan; consult the manufacturer regarding the material of the fan to ensure it is resistant to corrosion by acidic gases
You can choose a magnetic fan; visit www.shunda163.cn to take a look
The housing is lined with rubber; the fan is of explosion-proof type, and nitrogen sealing is used at the shaft seal.
Using flameproofing for acidic gases might not be appropriate; what concerns me most is the long-term corrosive effect of acidic gases on metal flameproof sheets, and whether this could lead to a \"pseudo-flameproofing\" effect.
FRP fans are used due to their acid resistance and low cost, while explosion-proof electrical components are employed.
