– FPM seals (V code in HYDAC catalog) can be used in place of our standard nitrile seals (NBR code in HYDAC catalog).
– BH can be used in place of BN but not the other way around.
– ECO/N and BN4HC elements can be interchanged as long as the customer is made aware that switching to BN4HC means metal components.
HYDAC works through a network of distributors. This list of distributors can be found on our website: Distributor
No we do not. We sell seals together in a seal kit. Part numbers for seals kits can be found in the filter maintenance instructions, which are located on our website: Catalogs (select the catalog in the list below or search Service and Parts with the search bar at the top).
Filter-IT can be downloaded from our German website: www.hydac.com
As a general rule of thumb, HYDAC recommends that the clean element pressure drop be no more than: 10-15% (at average flowrate) of the clogging indicator trip setting for lubrication systems, 20-25% for industrial applications, and 20-30% for mobile applications. Be sure to also check the pressure drop at cold start temperatures and maximum flowrates. If at these conditions the pressure drop is greater than 50%, then the next larger size should be selected. Note, make sure that the filter port size is large enough to handle the desired flowrate.
Why do you not offer Aquamicron water removal media with all of your filters? Does the Aquamicron remove free and dissolved water?Comments Off on Why do you not offer Aquamicron water removal media with all of your filters? Does the Aquamicron remove free and dissolved water?
Aquamicron media is designed for the removal of free water only. It does not remove dissolved water. The Aquamicron media captures water via a chemical reaction. The free (undissolved) water in oil reacts with the Aquamicron media to form a gel that is trapped within the element. Higher flowrates would not allow enough time for this chemical reaction to take place. Therefore the Aquamicron media is not available for high flow conditions.
A static clogging indicator is used in return line applications, where the filter outlet is open to atmosphere. Therefore, static indicators reference atmospheric pressure. Differential indicators are used in all inline applications.
As a general rule of thumb, HYDAC recommends FPM Fluoroelastomer (V code in HYDAC catalog) for water-glycols. However it is recommended that this requirement be verified with the water-glycol manufacturer. Paper (cellulose) media should never be used with water-glycol. In addition, differential indicators should include the ‘W’ model code option.
HYDAC recommends EPDM (EPR code in HYDAC catalog) seals and the appropriate SO modification as referenced in the ”Supplementary Details” section of the Model Code breakdown for each filter. Refer to the second page of the filter tech data sheet (also referred to as the sales brochure)
With proper o-ring seal selection, our filters are compatible with hydrocarbon-based fluids; including petroleum oils, synthetic oils, water-glycols, oil/water emulsions, and high water-based oils.
