1830020769 ATLAS COPCO Industrial Air Compressor Air Filter

1. Core Function and Working Principle

Air Inlet Filtration

This filter is installed at the front end of the air intake of the air compressor. Through the interception and adsorption effects of multiple layers of filtering materials, it can filter out impurities in the air, such as dust, sand particles, and fibers, ensuring that the air entering the compressor meets the cleanliness standards. Protective Equipment

If impurities in the air enter the main unit, it will accelerate the wear of precision components such as rotors and bearings, and also contaminate the lubricating oil, leading to a decline in lubricating oil quality and clogging of the oil filter, thereby shortening the service life of the equipment. High-quality air filters can effectively reduce such risks.

Ensuring Efficiency

A clean air filter can reduce intake resistance, ensure sufficient intake volume, and prevent the occurrence of reduced compression efficiency and increased energy consumption due to insufficient intake. 2. Common types and application scenarios

Dry air filter: The mainstream type uses paper or synthetic fiber filter materials and filters through physical interception. It is suitable for most dry environments and those with medium dust concentration.

Oil bath type air filter: Some older or special application models adopt this type. It adsorbs dust through an oil film and is suitable for high-dust environments, but maintenance is relatively complex.

The air filters for different series of air compressors have different sizes and interfaces and need to be matched with specific models. 3. Fault manifestations and impacts: Blockage

After long-term use, the filter material accumulates a large amount of impurities, resulting in increased intake air resistance. This manifests as a decrease in the exhaust volume of the air compressor, insufficient pressure, and increased motor load.

Damage or poor sealing

If the filter material tears, the frame ages, or the installation is improper, the sealing performance will deteriorate, allowing unfiltered air to directly enter the main unit, thereby causing wear on the core components. In severe cases, it may even lead to freezing of the main unit.

Reduced filtration efficiency

When the filter material gets damp, aged, or of poor quality, the filtration accuracy will decrease, and fine impurities will enter the system, accelerating the deterioration of the lubricating oil and clogging the oil filter.

Maintenance and replacement key points: Daily inspection

Regularly inspect the appearance of the air filter. If the surface is covered with dust, use compressed air to blow from the inside out for cleaning. But do not use water or oil for cleaning.

Observe the pressure difference gauge of the air filter. When the pressure difference value reaches the replacement threshold specified in the equipment manual, it must be replaced.

Replacement cycle

In normal environments, it is recommended to replace once every 2000 - 4000 hours;

In high dust environments, the replacement cycle should be shortened, or it should be replaced in advance according to the indication of the pressure difference gauge;

If the filter material is damaged, it must be replaced immediately to prevent impurities from entering the main unit. Installation precautions

Choose an air filter that is compatible with the original manufacturer;

Before installation, clean the dust inside the air filter housing to ensure that the sealing gasket is intact, and check the sealing condition after installation;

After replacement, reset the pressure difference gauge.
