When it comes to selecting a hydraulic filter there are many factors to take into consideration. Choosing the proper filter size will not only increase the operating life of the entire system, but it can also save you money. Wondering just how to select the right filter? Keep reading to learn about the 5 things to consider when selecting a hydraulic filter.
First things first, you need to understand that application that the filter will be used in. What are the performance requirements for the filter? This is typically expressed in a Beta ratio, which is often shown as efficiency percentages. Most filter manufacturers will define their filter’s performance by pore-size rating, but having an understanding of the performance requirements can help you select the appropriate filter.
Something else to consider is the hydraulic system as a whole. The other components installed in the system will directly affect hydraulic filter selection. You need to make sure whatever filter you select will function according to industry standards and also meet the standards of the other components contained in the system.
When selecting a hydraulic filter, you also want to examine the clogging indicator. As a general rule, the ratio used for the clogging indicator to the clear pressure drop needs to be at least 3:1. By not understanding the clogging indicator, you risk sizing your filters incorrectly and increasing your costs.
One component that is often discounted when it comes to selecting a hydraulic filter is viscosity. However, this has a big impact on filter sizing and needs to be carefully considered. By not understanding viscosity and oversizing the filter you can experience unnecessarily high operating costs, higher replacement costs, and a larger footprint. If you understand the normal temperature range, you can select a filter that is appropriately sized and will not prematurely go into bypass mode.
When sizing filters for your hydraulic system, the flow rate is extremely important. You need to be aware of the maximum flow rate and simultaneously understand that system flows can intermittently far exceed the max flow for the pump. When selecting a filter, take the flow rate immediately downstream into account.
