What Is A Hydraulic Filter?

There are several different filters, but what is a hydraulic filter? The three basic types are pressure, return line, and spin-on filters. These filters are all designed to deal with the pressure drop through the filter element. Still, they benefit from allowing oil to bypass the filter element and continue the system running without filtering. 

Reservoir breathers

Breathers are necessary for hydraulic systems, but adding fluid to the reservoir presents many opportunities for introducing contaminants. The fluid may have been exposed to pollutants during transportation or storage. In addition, some hydraulic systems operate in dirty environments. The presence of these contaminants around the reservoir’s filler breather can cause the components to fail prematurely. Fortunately, there are many ways to detect if the filter element needs replacement and avoid such a scenario.

When choosing a reservoir, consider the type of hydraulic system you plan to use. A standard volume of the reservoir should be at least three to five times the pump’s flow rate. While 2.5 times the pump flow is sufficient for most industrial applications, you may require a larger tank in cases where the fluid level is higher than the pump’s inlet line. Alternatively, you may opt for a smaller hydraulic filter that is less bulky and more lightweight.

Spin-on filters

In Latin America, the market for Spin-On hydraulic filters is expanding rapidly, with the production of cars increasing by 14.6% in the first three months of 2018, according to the National Association of Automobile Manufacturers Anfavea. With domestic demand rising, manufacturers increased their production volumes to meet the increased demand. However, these increased production costs are not resulting in higher sales. This growth in vehicle production is affecting the need for spin-on hydraulic filters.

Automatic changeover filters

Hydraulic changeover filters are installed in lubrication and hydraulic systems. The switch between the two filter housings is accomplished through a mechanical, optical maintenance indicator. The filtered fluid enters the hydraulic circuit through the outlet of the filter element, and the filtered fluid exits through the clean filter chamber. Changeover filters allow the system to run 24 hours a day without shutting down. They also feature a rotation limitation.

Hydraulic changeover filters can either be in the return line or pressure line. Depending on the type of hydraulic system, the return line filter should withstand higher pressure than the pressure line puts out. On the other hand, a return line filter will withstand the back pressure of the flow, which fluctuates due to the intensity of the flow and the pressure differential generated by the clogged element. To operate this correctly, the filter must slightly exceed the back pressure. Otherwise, it will not function during normal pressure fluctuations.

Return line filters

Before you can start using hydraulic return line filters, you have to install them properly. Although you can hire a professional to do this work, it will cost you more. However, it will save you from the hassles of hiring an expert and prevent you from undergoing any inconvenience. First, you have to switch off the machine and install the filter close to the reservoir. This will prevent unfiltered fluid from flowing back to the device.

Another essential feature when choosing a hydraulic return line filter is its size. A return filter must be large enough to contain the fluid flowing through it. It should also be compatible with the temperature of the fluid. This is important because the filter element may rupture or become too small to handle the pressure. The right size for the system is crucial since it will prevent the system from being damaged by contaminated fluid. However, it is vital to consider the size and shape of the return line filter to ensure that it fits properly.

Off-line filters

Hydraulic off-line filters are devices used to purify operating fluid in hydraulic systems. These filters are useful for industrial applications as they reduce the wear of hydraulic components. Off-line filters are available for both hydraulic and pneumatic systems. This article looks at the various types of hydraulic filters available. Here are some examples. All of these products are suitable for industrial and hydraulic applications. You can find one that fits your needs. 

In addition to protecting downstream components, off-line hydraulic filters can ensure lubricant cleanliness. New hydraulic fluid can contain environmental contaminants like paint chips, rubber particles, metal shavings, etc. The air hose is not always effective in removing larger contaminants, so a hydraulic filter cart is necessary. It’s also best to use pre-filtered fluid which meets specifications. Hydraulic offline filters help you avoid these problems.
