SUBSTITUTING FILTERS | |
|
Today there is an ever increasing number of filter applications in automotive, heavy-duty and industrial businesses. This, of course, results in larger inventories for filter manufacturers and distributors. This situation may make some distributors want to reduce the number of filters they must inventory by consolidation.
While there are many filters that seem similar and, in fact, fit some of the same applications, we strongly recommend exercising caution when making substitutions. The internal components of certain filters may differ while the filters appear to be identical. The internal components include: anti-drainback valves, by-pass valves, post seals and filtering elements, among others. Each of these components has a specific purpose in the function of the filter and must be considered when substituting filters to assure that the performance of the required filter is not impaired. |
A difference as simple as the setting of the by-pass valve, with all other components being the same, can affect the protection the filter provides for the equipment. Hastings Filters evaluates the filters recommended by the original equipment manufacturers to design the proper Hastings replacements. Our engineering practices assure that our filters meet or exceed the performance requirements of the respective original equipment manufacturers. These measures enable Hastings Filters to provide warranty on the applications of our filters without affecting the original warranties of the equipment manufacturers.
Substituting filters with "will fit" replacements that are not listed by the application may affect or even void the warranty on both the filter and the equipment. Use only the product specified in the current Hastings Filter Interchange and Application guides to assure the proper filtration performance is achieved. |
