Stainless Steel Filter Driers to Trap Moisture

Molecular Sieve Filter Driers

A filter drier captures moisture and contaminants during the recovery process of the extraction solvent as it passes through the molecular sieve on its way to the condenser coil or recovery tank. This filtering process combines the micro-porous 2500 mesh (5 micron) gasket which excludes dust particle contaminants. The remaining vapor passes through the gasket into the stainless steel cannister which is commonly filled with a dessicant to remove moisture. A drier filter cannister typically consists of:

  • 2 x Tri Clamp Bowl Reducers w/ FNPT ports
  • 2 x Tri Clamp 2500 Mesh Screens (Viton or FKM)
  • 2 x High Pressure Clamps
  • 1 x 12 - 24+ inch Tri Clamp Spool

How Do Molecular Sieve Driers Work?

A molecular sieve relies upon a method called physical adsorption (as opposed to absorption - chemical integration). Adsorption is when one substance is held inside another by a physical bond. In a porous dessicant such as silica gel, activated clay or charcoal, water is removed through the attraction of thin layers of water molecules to the surface of the dessicant. Dessicants by their nature are very porous and thus have a lot of surface area to attract a large volume of water molecules.
