Construction and mining equipment work at extreme environment and weather conditions that involve a lot of dust, temperature variations and uneven terrains. Large volume of dust and enormous mechanical loads place filtration systems under a lot of pressure. These extraordinary working conditions require filters of special features that can withstand these adverse conditions and keep the machines safe from contaminants. The role of filter in equipment is to maintain the cleanliness to achieve the optimal performance, increase engine and equipment protection, extended service interval, reduced downtime and increased equipment efficiency and productivity. Modern mining and construction equipment require advanced filtration to maximise the performance and reliability. The different filter systems in an engine or hydraulic systems have to filter the operating materials such as air, fuel and oil. Filters in OE matching quality provide the best possible protection for the machines. They reduce machine downtimes and make sure that the machine users are complying with the prescribed service intervals of the machine manufacturer. The market for hydraulic filters is looking forward for a growth in the coming years due to the demand expected from infrastructure development and industrial growth. In spite of the current slowdown, the market is expected to bounce back in the near future with the execution of the planned projects to take off while new projects in the planning stage.
Another growth driver for filters will be the implementation of the next level of emission regulations in 2020 for on-road and off-road vehicles. Efficient filtration systems can help manufacturers meet stringent emission regulations requirements, be it fuel filters, engine oil filters or air filters. The latest emission standards in India will require the sulphur content in diesel fuel to drop to 10 ppm from the existing 50 ppm. In order to maintain the lubricity on the fuel, additives are combined with the fuel, which do not allow the water content in diesel to be separated easily. This poses a key challenge in the separation of small water particles that are up to 10 microns in size. Filter manufacturers like Mann and Hummel have come up with special water separation filter for diesel fuels. They have also introduced various other filtration solutions for the construction and mining equipment market. The Special Focus section explains more.
