Construction and mining machinery operate in extreme conditions of weather, terrain and environment. They need to withstand all these odd conditions and perform the task with minimum downtime. Machine uptime and efficiency are the most important for these machine in project execution. Engines and hydraulic parts that power the machine needs to be safe from dust and foreign particles mixing with hydraulic oils and fuels. Oils and fluids may get contaminated during filling transportation with the chance of mixing dust, dirt, and other foreign particles with the hydraulic fluid. This can severely damage the engine and hydraulic system of the equipment leading to machine breakdown.
Filters play the most important role in preventing foreign particles and contaminants going into the engines and hydraulics. Without the use of a filter, fluid power systems are incomplete. Hydraulic filters support the efficiency and long life of industrial equipment by removing micron size dusts and particles from the hydraulic fluid in the heart of the machinery. A filter should be of minimum quality for the most sensitive hydraulic component in the system.
Modern mining and construction equipment incorporate state-of-the-art technology that requires advanced filtration to maximise performance and reliability. Today's application requires longer filter change intervals, higher operating safety, increased separation efficiency and increased compatibility with new generation of hydraulic oil. High-performance filters maintain the cleanliness of the hydraulic fluid over its entire service life. Most high-performance filters are double-layered. These layers consist of a coarser pre-filter layer to capture the larger particles and a main layer to trap smaller particles. The combination of the pre-filter and the fine filter layer increases the dirt-holding capacity and improves oil cleanliness.
The global hydraulic filter market is forecast to grow at a CAGR of 4.4 per cent from 2018 to 2023. The major drivers of growth for this market are increasing production of construction, mining, and other equipment, development of innovative and energy efficient hydraulic filters, and increased focus on preventive maintenance of hydraulic equipment and systems.
With the market in India graduating to the next level emission regulations soon, meeting the emission levels with adequate changes in the hydraulic systems is of utmost importance. Filters have a major role to play in meeting the future emission norms and keeping the equipment clean and green with better efficiency.
