Geely Global Eagle GX2 Golden Eagle Great Wall Brilliant 1.3 British Chariot 2000 Diamond 1.5 Air Filter

Air filter is used to filter the air in the engine to avoid harmful substance from being sucked in, including dust, soot, smog, pollen and other pollutants. If these substances enter the engine, it will increase the abrasion between the piston and the cylinder and lead to fuel to be mixed into the combustion chamber, thus increasing the engine fuel consumption and exhaust emissions, decreasing the engine power and shortening its service life.

When driving a certain mileage, a large amount of dust and impurities will accumulate the surface of the air filter, resulting in a decline in air permeability, therefore, the air filter must be replaced regularly.

BENEFITS

1. Clean the air that goes into the engine, holding the dust and abrasive particles in the filter, thereby avoid engine wear and tear
2. High dust separation efficiency.
3. Help maintain regular fuel consumption.
4. Reduce engine noise and optimize performance.

AIR FILTER STRUCTURE

★ Structure of Filter Paper Air Filters for Light Vehicles

1. Filter media: plant fiber pleated filter paper
2. Frame: polyurethane sealant molding frame is used to ensure the best fit and sealing.
3. Optional support mesh type
(1) Expanded metal mesh
(2) Perforated metal mesh
(3) Perforated plastic mesh
4. Optional pre-filtration layer type: In high dusty areas, air filters are provided with a pre-filtration layer.
(1) Sponge
(2) Non-woven fabric

★ Structure of Non-Woven Fabric Air Filters for Light Vehicles

1. Filter media: non-woven fabric Filter media is suitable for high humidity filtration environments.
2. Solid propylene structure.
3. Sealing polyurethane gasket: good sealing effect.

★ Structure of Single Element Air Filters for Heavy Duty Vehicles

1. End caps: it consists of a top cap and a bottom cap to combine the filter element together.
(1) Metal end caps: provided with a gasket
(2) PP plastic end cap
(3) Polyurethane (PU) end cover: high strength polyurethane structure, with better adhesion and sealing.
2. Inner support tube: It plays a role of supporting the Filter media and improving the stability of the Filter media. There are main three types:
(1) Perforated tubes
(2) Expanded metal mesh
(3) Plastic tube (generally used with PP end caps and PU end caps)
3. Filter media: high filtration efficient, pleated filter paper;regular folding space creates a higher dirt holding capacity.
4. Optional additional reinforcement layer: Provide additional reinforcement to the pleated filter paper. There are three main types:
(1) Beading stabilises the media and prevents pleat wear.
(2) Plastisol spiral winding fixation
(3) Filament spiral winding
5. Optional outer support tube: perforated metal mesh or expanded metal mesh is employed to reinforce and protect the filter media, making its structure more stable forming.

The Air Filter is a remarkable device that serves a crucial purpose in various settings. It is designed to purify the air by trapping and removing a wide range of contaminants.

This essential component is often found in HVAC systems, automobiles, and industrial environments. In HVAC systems, the Air Filter works diligently to filter out dust, pollen, mold spores, and other airborne particles, ensuring that the air circulated within a building is clean and healthy. It helps to create a comfortable and allergen-free environment for occupants.

In the automotive sector, the Air Filter plays a vital role in maintaining the engine's performance. It prevents dirt, debris, and small particles from entering the engine, which could cause damage and reduce its efficiency. A high-quality Air Filter ensures a proper air-fuel mixture, leading to better engine combustion and improved fuel economy.

Constructed with precision, Air Filters typically consist of a filter media that is highly effective at trapping contaminants. The filter media can be made of various materials such as paper, fiberglass, or synthetic fibers. These materials are selected for their ability to filter out specific particle sizes while allowing for proper air flow.

Regular replacement of the Air Filter is essential to maintain its effectiveness. Over time, the filter can become clogged with accumulated contaminants, reducing its filtration efficiency and potentially causing issues such as restricted air flow or reduced system performance. By replacing the filter at recommended intervals, you ensure that the air purification process remains optimal.

The design of the Air Filter may vary depending on its application. Some filters are disposable, while others can be cleaned and reused. Additionally, there are different grades and efficiencies of Air Filters available to meet specific needs and requirements.

In industrial settings, specialized Air Filters are used to handle large volumes of air and more complex contaminant mixtures. These filters are often custom-designed to fit the specific needs of the industry, ensuring that the air quality meets strict standards.

In summary, the Air Filter is an unsung hero that silently works to improve the quality of the air we breathe and the performance of various systems. Its importance cannot be underestimated, as it helps to create a healthier and more efficient environment in countless applications. By choosing the right Air Filter and maintaining it properly, we can enjoy the benefits of clean air and reliable system operation.
