Wheel Loader Air Filter

Wheel Loader Air Filter

Wheel Loader Air Filter is an important component of the engine intake system, mainly used to filter out suspended dust, sand and other impurities in the air entering the cylinder, prevent them from accelerating the wear of the piston group and cylinder, and avoid larger particles from entering and causing "cylinder pulling" phenomenon.

Air filters usually consist of a two-stage filtration structure consisting of a main filter element and a safety filter element, and some models are also equipped with swirl plates as pre filtration devices. The main filter element adopts a paper dry filter element, which achieves efficient filtration through microporous filter paper; As a secondary protection, the safety filter element continues to protect the engine when the main filter element fails. The cyclone plate uses centrifugal force to separate large particles of dust and discharge them through a dust bag, which is particularly effective in dry and sandy conditions.

Precautions for use

Maintenance Cycle

Regular maintenance: When the air filter blockage indicator light is on, immediate maintenance is required, and the cycle should be shortened under harsh working conditions.

Filter replacement: The paper filter needs to be replaced after 4 maintenance cycles. If it breaks, punctures, or the filter paper peels off, it should be replaced immediately.

Dust removal system: Regularly clean the dust bags and collection cups to ensure that the dust particles do not exceed 1/3 of the height and avoid secondary pollution.

Operating specifications

Cleaning method: Use compressed air below 0.2MPa to blow back from the inside of the filter element, with the nozzle 10-20 centimeters away from the filter material. Do not knock or wash with water.

Installation requirements: When replacing the filter element, ensure that the sealing strip is not damaged, install rubber washers on the end face of the filter element, and fix the wing nut with moderate force.

Environmental control: Choose a windless and dust-free environment during maintenance to prevent impurities from entering the engine.

Fault handling

Indicator light alarm: Immediately stop the machine and check for clogged filter cartridges. If necessary, clean or replace them.

Abnormal power: When the engine is weak or emitting black smoke, it is necessary to check for clogged filter elements or intake short circuits.

Component damage: When the dust valve, sealing strip, etc. are damaged, they should be replaced in a timely manner. It is forbidden to repair the damaged filter element.

Adaptation to working conditions

High dust environment: Choose an air filter with increased capacity to shorten the replacement cycle of the filter element.

High altitude working conditions: Adopting a swirl type pre filter or wet air filter to improve the coarse filtration efficiency.

Moisture prevention measures: In rainy and snowy weather, it is necessary to ensure that the rainproof cap functions properly to avoid the filter element absorbing water and increasing the intake resistance.
