1. If the filter element is not cleaned or replaced regularly, a large amount of dust will accumulate in the air filter. Once the air filter is completely blocked by dust, the intake resistance of the truck will be greatly increased and the intake volume will be reduced, resulting in incomplete fuel combustion, which will reduce the engine power and economic performance.

2. If the filter element is not replaced beyond its service life, it will be damaged and lose its filtering function. A large amount of dust will enter the cylinder, which will also cause accelerated wear of other important parts of the truck. In addition, the dust will also enter the oil pan through the piston ring clearance, which will bring adverse consequences to the lubrication system.

3. If working without an air filter, the wear of the piston and cylinder liner will increase 3-5 times, and the wear of the piston ring will increase 8-10 times. Therefore, it is of great significance to maintaining the air filter in strict accordance with the technical requirements.

Basic steps of truck air filter maintenance and the advantages of the truck air filter of CNHTC:

• During installation, the air filter and the engine intake pipe must be tight and reliable to prevent air leakage and affect the filtering effect. Rubber washers must be installed at both ends of the filter element; The wing nut fixing the air filter cover cannot be tightened too tightly to avoid damaging the paper filter element.The air filter of CNHTC uses nano filter material, which can reduce the filter resistance and increase the driving power of the truck.
• During maintenance, the paper filter element shall not be cleaned with oil, otherwise,the paper filter element will become invalid, leading to flight accidents. During maintenance, the dust and dirt attached to the surface of the paper filter element can only be removed by vibration, soft brush or compressed air blowback. The coarse filtration part shall timely remove the dust from the dust collection part, blades and cyclone tubes. The fine ash holding capacity of the air filter of CNHTC is particularly high, which will better protect the engine and our trucks.
• When using, the air filter shall be strictly prevented from being wetted by rainbecause once the paper core absorbs a large amount of water, the air inlet resistance will be greatly increased, and the service life will be shortened. In addition, the paper core air filter cannot contact oil and fire. The service life of the air filter of CNHTC is longer than that of other brands of air filters, so even if the paper core absorbs water, its resistance will be relatively small.
• In fact, the filter manufacturer does not encourage drivers to dismantle and clean the air filter system. After all, no matter how much cleaning is carried out, the filtering effect will be greatly reduced. In general, cleaning shall not exceed 3 times every 10000 km. But like the air filter of CNHTC, it can maximize mileage and reduce maintenance costs comprehensively. However, if you are in a dusty place, such as a construction site or desert, you should shorten the maintenance mileage accordingly to ensure that the engine can breathe smoothly and cleanly.
