Compatibility of Filter Media.
Filter media can be divided into two broad categories, natural fibres (usually cellulose) and synthetic or man made fibres (usually fibre glass or woven wire mesh), although many different variations and types of media do exist, many filters fall into one of these two categories.
|Fluid to be Filtered||Recommended Media|
|Petroleum-based||Cellulose, Glass fibre|
|Phosphate Ester||Glass Fibre|
|Water Glycol||Glass Fibre|
|Water-Oil Emulsion||Glass Fibre|
|Biodegradable Fluid HWCF*||Glass Fibre|
|Course Filtration||Wire Mesh|
* High water content filtration
Notes on seals:
Filters with seals made of BunaN are appropriate for most applications involving petroleum oil and some high water content fluids. Filters with seals made of Viton® of Fluorel® (both fluoroelastomers) are required when using diesters, phosphate ester fluids.
