Demister packing as separating stages:

Pre-separation by expansion effect
Pre-separation by baffle plate deflection (inertia forces)
First wire mesh stage (demister) serves as agglomerator for small
droplets (1 - 2�m)
Second wire mesh stage (inertia, screen and diffusion effects)
Third Stage as safety stage (e.g. glass fibre packing)
Secondary filtering stage if required (for fumes, vapours or odors)
Spraying device for first stage if required (automatic timer control)


Pure stainless steel wire mesh Glass fibre packing Combined packing of stainless steel and glass fibre The combination of material for the filter elements depends on the application, particulary the cooling lubricant (soluble or non-soluble oil). The following characteristics must be optimized: Fibre packing volume Fibre diameter Porosity Wetability
