"Fine Filters" Compressed Air /Gas Filters consist of a two-stage
separation-cum-filtration process.
Typical Applications include filtration of compressed Air/ N2/ CO2/ Cl2/ Natural gas/SO2/NH3 etc.
In the first stage, the air/gas passes through a carefully positioned Demister
Pad placed above the inlet nozzle.
The Demister Pad is made of knitted St. Steel wire loops with symmetrical
interlocks. Due to the high free volume and large impingement area, it has a
very low pressure drop. As the air/gas passes through the pad, the liquid
droplets contact the large wire surface area and due to the greater inertia,
they are held back. As more and more droplets collect, they coalesce and
grow in size and then fall back in the drain sump due to gravity.
The air/gas exiting out from the top of the Demister pad will contain traces of
oil and moisture in mist form in the range of about 25-30 microns.
In the next stage, the air/gas enters the porous ceramic filter elements
hanging above the Demister Pad.
