Air conditioning filter - one of the components of air conditioning.
Car air filter is an item to remove particulate impurities in the air in the car, car air conditioning filter can effectively reduce pollutants through the heating ventilation and air conditioning system into the car, to prevent the inhalation of harmful pollutants.
Car air filter is mainly responsible for removing particulate impurities in the air. When the piston machinery (internal combustion engine, reciprocating compressor, etc.) works, if the air contains impurities such as dust, it will aggravate the wear of the parts, so it must be equipped with an air filter. The air filter is composed of two parts: a filter element and a housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and can be used continuously for a long time without maintenance.
The car engine is a very precise part, and the smallest impurities will damage the engine. Therefore, before the air enters the cylinder, it must first pass through the fine filtration of the air filter to enter the cylinder. The air filter is the patron saint of the engine, and the condition of the air filter is related to the life of the engine. If the dirty air filter is used in the car, the engine intake will be insufficient, so that the fuel combustion is incomplete, resulting in unstable engine work, power decline, and increased fuel consumption. Therefore, the car must keep the air filter clean.
Customers are usually advised to replace it every 15,000 kilometers driven. Vehicle air filters that often work in harsh environments should be replaced no more than 10,000 kilometers. (desert, construction site, etc.) The service life of the air filter is 30,000 kilometers for cars and 80,000 kilometers for commercial vehicles.
Filter requirements for automotive air conditioning filters
1, high filtration accuracy: filter out all large particles (> 1-2 um)
2, high filtration efficiency: reduce the number of particles through the filter.
3, prevent early engine wear. Prevent air flow meter damage!
4, low pressure difference to ensure that the engine has the best air-fuel ratio. Reduce filtration losses.
5, large filter area, high ash capacity, long service life. Reduce operating expenses.
6, small installation space, compact structure.
7, the wet stiffness is high, prevent the filter from sucking and deflating, causing the filter to be broken down.
8, flame retardant
9, reliable sealing performance
10, good cost performance
11, no metal structure. Environmentally friendly and reusable. Good for storage.
The disassembly process of the automobile air filter housing mainly includes the following steps :
Confirm the position of the air filter : First of all, you need to open the engine cover and confirm the position of the air filter. The air filter is usually located on the left side of the engine compartment, above the left front wheel. You can see a square plastic black box in which the filter element is installed .
Removing the housing : There are four clasps around the housing of the air filter, which are used to press the plastic housing above the air filter to keep the air inlet pipe sealed. The structure of these clips is relatively simple, just gently snap the two metal clips upward, you can lift the entire air filter cover. If the air filter is fixed with screws, you need to choose a suitable screwdriver to unscrew the screw on the air filter box to open the plastic housing .
Take out the filter cartridge : After opening the plastic case, you can see the air filter cartridge inside. Directly remove the filter element from the air filter, if you need to clean, you can use compressed air to blow from the inside out to remove the dust. At the same time, the dust in the air filter shell can also be removed. If there is no compressed air, beat the ground with the filter element to shake out dust, and then clean the air filter shell with a damp cloth .
Replace new filter element : If a new air filter element needs to be replaced, install the new air filter element into the air filter housing, and then fasten the edge clamp or screw the housing. Ensure that the filter element and the filter tank are well sealed to ensure the filtration effect, and ensure that the position of the shell and the filter element is aligned to ensure the normal work of the air filter element .
Through the above steps, the removal of the car air filter shell and the replacement of the new filter element can be completed. The process, while requiring some skill and patience, can be done with ease as long as the right steps are followed .
