Filtration of Solvents and Solvent Mixtures

Solvents are widely used in manufacturing and cleaning processes e.g. pharmaceutical, cosmetics, paints, inks, degreasing, chemical manufacturing etc. and filtration is frequently used for particulate removal, polishing, and regeneration. Solvents are usually hazardous and designing a filtration system for filtering solvents requires careful consideration. When designing or specifying filters for solvent applications, we take the following factors into account:

Application requirements:
Micron rating and degree of filtration required, hygienic or industrial application, single use or multi pass, batch or continuous.

Process conditions:
Flash point, vapour pressure and fluid state of solvents are carefully assessed before making a selection.

PED compliance:
We use solvent data to establish correct fluid groups and categories for PED compliance. All filter housings are fully compliant with Pressure Equipment Directive.

Material Compatibility:
We check material compatibilities of all wetted parts to ensure that offered materials will retain their physical properties during operation. Our standard material of construction for filter housings is Stainless Steel which is compatible with a wide range of solvents. Filter elements and bags are available in a range of polymers and Stainless Steel. In addition, we can also supply fluoropolymer lined vessels for aggressive media and 100% PTFE elements and bags.
