Demister Pad

Stainless Steel Demister Pads
Filson stainless steel demister pad is the most common choice in all metallic demister pads, among the widely used materials are SS 304 and SS 316L. It features great anti-corrosion and anti-temperature abilities.
PP Demister Pad
Filson PP(polypropylene) demister pad is the lightest type among all materials with 0.90-0.91 g/cm3 density. It mainly consists of PP knitted wire mesh and PP support gratings, owns excellent tiny drop removal ability.
PTFE Demister Pad
Filson PTFE(polytetrafluoroethylene) demister pad, or called Teflon/F4 demister pad, features superior acid&alkali and insulation resistance. Widely used for chemical, petroleum, pharmacy, etc. high corrosive industries.
PE Demister Pad
Filson PE(polyethylene) demister pad is non-toxic, safe for food industries, resistant to acid, alkali, saline solution but unsuited for strong alkaline detergent. Can be designed into your needed diameter and thickness.
PVC Demister Pad
Filson PVC(polyvinyl chloride) demister pad has good flame resistance with efficiency of 40%, which is more than PP demister pads and PE demister pads. And it is toxic since the special chemical components, thus do not recommend for use in food industries.
Monel 400 Demister Pad
Filson Monel 400 demister pad is an unique nickel-cooper alloy demister type, has outstanding temperature resistance which can withstand from below zero to 480℃. Heat exchanger, feed water and stream generator tubing are its typical applications.
Titanium Demister Pad
Filson titanium demister pad is your optimal gas-liquid separation solution for evaporators, refining vacuum towers, refining lube towers, steam drums, scrubbers, separators vessels. It is resistant to dilute sulfuric and hydrochloric acid, most organic acids and chlorine gas, etc.
Fiber Demister Pad
Filson fiber demister pad, also called fiber bed mist eliminator, is usually manufactured in a cylinder shape with hollow design. Whether the filtering direction is in to out or out to in, all can be designed depending on your site condition.
Wire Mesh Demister Pad
Filson wire mesh demister pad, or named demister mesh pad, is composed of knitted wire mesh and support grids, or no grids design is available. It can separate tiny liquid entrainment down to 3μm with over 99% efficiency.
Vane-type Demister Pad
Filson vane type demister pad, or called vane type mist eliminator, is an unusual style which consists of closely spaced corrugated plates. Unlike mesh type demister pads, vane type demister pads effectively work on droplets larger than 20 microns.
Demister Filter
Filson demister filters, also called mist eliminator filters, commonly include mesh demister pads, vane mist eliminators, fiber bed mist eliminator(candle demister filter), cyclone mist eliminators. All of them are good at separating liquid entrainment from vapor stream which is highly contaminated.

What is Demister Pad?

Demister pad is an essential device in various packed columns, rectifying columns, separation columns, cooling towers, etc., generally located at the top. It is used for removing specified size liquid entrainments from gas streams.


Mainly consist of knitted wire mesh and support grids, demister pads can be manufactured in stainless steel, nickel, monel, hastelloy, inconel, PP, PE, PVC, PTFE(Teflon) or other required materials. And for different application and installation needs, it can be designed into various shapes like standard round, rectangular, ring types or special wave-shaped. Vane-type is also available.

How do demister pads work?

The main principle of demister pad is coalesence by inertia. When tiny liquid entrainments passing through the tortuous path of demister pad, they collide with each other between the gaps of knitted wires and condense into larger liquid droplets. Weight gain, droplets drop down. Thus the mist will be separated from gas streams and you can obtain the pure gases.

How to clean a demister pad?

Regular and proper maintenance of demister pad is important. After a period of using, your demister pad may be clogged by the particles in the gas and pressure drop will increase, then you need to clean it. Various cleaning methods will be mentioned here including spray with cleaning liquids, boil, soak… to help you regain a clean demister pad while recovering its high filtration efficiency.

Please be more careful when you cleaning the demister pad, and carefully check for damage after each cleaning. Measure its wire diameter with a micrometer to confirm if there is any change compere to the brand new. In addition, a spare demister pad is necessary before you start cleaning.
