Vane mist eliminator/Baffle demisters, also known as plate-type demisters, are designed to efficiently remove larger particles and dust from gas streams in separation towers. Compared to wire mesh demisters, baffle demisters excel in applications requiring recovery of coarser mist droplets and solid particulates.
They are widely applied in chemical processing, refining, and environmental protection systems where heavy-duty mist removal is essential for product purity and equipment protection.
There are two main types:
C-type (double-channel) baffles with blade heights about 175 mm (200 mm including top and bottom holders)
S-type (triple-channel) baffles with blade heights around 235 mm (250 mm including holders)
Blade thickness options usually include 1.0 mm and 0.8 mm, with 1.0 mm being the most common. Blade spacing varies between 20 mm, 25 mm, 30 mm, and 40 mm, where 30 mm is a popular standard.
Materials commonly used are stainless steel grades 201, 304, and 316L, as well as polypropylene (PP) for corrosive environments. PP baffle demisters feature streamlined blades with 3 mm thickness.
Baffle demisters provide robust and reliable mist elimination performance, especially suitable for harsh industrial conditions.
Key features include:
Effective removal of large mist droplets and dust particles
Strong mechanical strength - ideal for heavy-duty applications
Wide range of materials - stainless steel and PP for chemical resistance
Customizable blade spacing and thickness - optimized for different gas flow rates and mist loadings
Easy installation - typically installed in one or two layers within the tower
Low pressure drop - maintains process efficiency while capturing mist
