Resistant to mineral oil, fuel, and chemicals, our media achieve low ∆P and good processability. They are available with different water/oil repellency levels. H&V’s coalescer media are an ideal choice for the following applications:
- Removal of 95% of water from diesel fuel and virtually 100% removal of water and solids from jet fuel
- Foreign liquid purification for industrial liquids like coolants and hydraulic fluids
H&V offers a full line of solvent and water-based media. Phenolic, epoxy, and acrylic resin treatments meet customer durability and environmental requirements.

Frequently Asked Questions:
Q) Why are glass fiber media preferred versus standard cellulose media for coalescing applications?
strong> A) Glass fiber media are preferred because the smaller diameter fibers provide a better relationship between water elimination and differential pressure than other media.
Q) Are there industry standards on water removal ?
A) Water must be reduced to a maximum of 5 ppm in military applications and to a maximum of 15 ppm for civil applications. H&V coalescing media achieve these targets.
Q) Is a prefilter needed?
A) A prefilter will increase the lifetime of a filter. Typically a wood pulp is used in this media type.
