Hydraulic filters keep contamination from circulating in hydraulic oil, protecting critical system components from damage and preventing costly downtime. They clean hydraulic fluid by trapping particles that would otherwise damage pumps, valves and cylinders. Most equipment manufacturers provide guidelines for when to change filters, but this method only accounts for some of the variables that can affect filter life. Instead, using data to monitor system performance can help you know when your filters should be replaced.
Many hydraulic systems rely on fluid power to activate controls, operate equipment, and deliver precision movement. However, the system can quickly become impaired by any contaminants entering the fluid. It includes solid particles, water, air, and reactive chemicals that harm critical functions, leading to unscheduled downtime and costly repairs. Hydraulic filters reduce downtime by preventing particle buildup and continuously cleaning the hydraulic oil. They also protect against sludge formation, reducing the risk of critical component seizure.
Most filters have a screen or filter element that traps contaminants, allowing clean hydraulic oil to pass through. They are designed to withstand various system pressures and may have a bypass valve allowing the fluid to flow around the filter if it becomes too clogged with contamination. Hydraulic filter suppliers VA offer various form factors to suit different applications. Many buyers will purchase a filter assembly with the filter media or cartridge and the housing attached.
Reduced Maintenance Costs
Hydraulic systems are the backbone of many mechanical equipment. They provide force transmission, lubrication, and cooling by circulating hydraulic oil throughout the system. But, as these fluids circulate through the system, they become susceptible to contamination that could create wear or lead to component failure. Manufacturers often recommend maintenance practices for their machines, including filter changes. However, following this practice can lead to inexpensive and inexpensive repairs.
A more efficient way to reduce costs is by utilizing preventative maintenance strategies, including oil testing and proper filter replacement. This maintenance type aims to catch issues before they impact equipment performance and profitability proactively. Having the right hydraulic filters in place is one of the best ways to achieve this.
Improved Hydraulic Performance
An uninterrupted flow of clean hydraulic fluid leads to equipment with lower friction and wear, which improves overall functionality. It also enables equipment to operate longer and with fewer maintenance updates. Filters remove contaminants to keep system fluid clean and able to transmit force equally across components. It prevents contaminant buildup that causes equipment to seize, which could lead to expensive repairs and downtime.
Tank-mounted filters protect the hydraulic system from air contamination entering a reservoir as it drains. Breather filters prevent atmospheric contamination from entering a system as the fluid level drops in a tank and are available in risers, dipsticks, spin-on styles, or threaded breathers.
Increased Equipment Life
Hydraulic filters help extend the lifespan of expensive hydraulic equipment by preventing the wear and tear that contaminants can cause. It translates to a longer lifespan for your hydraulic equipment and a reduced need for costly maintenance or replacements. Clean hydraulic fluid is also more energy efficient than dirty fluid. Contaminants in the hydraulic system create friction and resistance that requires a lot of energy to overcome. Hydraulic filters remove these contaminants, allowing the hydraulic system to operate at peak efficiency and saving you money on energy costs.
Most Hydraulic Filters systems come with recommended maintenance practices from the manufacturer that tell you when to change your filters. Many of these recommendations are based on operational hours, which can be a good starting point. Still, other factors must be considered when determining the right time for filter changes.
