Stainless Steel Knitmesh Mist Eliminator/Wire Mesh Demister ,Round or Rectangle Shape
Size and structure can be customized according to customer's drawings.
1.what's demister pad
DEMISTER PAD is wire mesh blanket with or without frame used to remove process liquid carried over which from's during boiling vacuum evaporations or bubbling Process. it consists of multiple layers of knitted and crimped monofilament ( 0.254 mm) wire mesh fabric. The knitted and crimped mesh increases contact surface and porosity of fabric, prevents blocking and gives constant porosity throughout the metal due to this separation efficiency increases up to 99 % at lower pressure drop & gas velocity.

5. PRODUCING PROCESS
6. clafffication based on installation method
According to different installation method,demister can be divided into top-loading type and bottom-loading type,respectively called S and X for short
Screen defoaming device have tops, bottoms, DG200 - DG6400 and various non-standard screen defoaming,
| Jacket type screen drift diameter in the range of defoaming device | DN300~ DN5400MM |
| Bottoms screen drift diameter in the range of defoaming device | DN700~DN6400MM |
7.Demister application
Wire Mesh Demister are widely used in chemcial industry.
It can remove 3~10 μm entrainment with low pressure drop, usually under 250pa.
