2901200610 Oil Filter Atlas Copco air Compressor KIT FILTER SEPARATOR 1625426100 Original

I. Atlas Copco Air Filter Components

Air filters are used to remove dust, particles, moisture, and other impurities from the incoming air, preventing them from entering the air compressor main unit (such as screw, piston, etc.), avoiding wear, blockage, or corrosion of internal parts, and reducing the burden on subsequent processing equipment.

Main components:

Filter housing (outer shell)

Made of metal or high-strength plastic, it has certain sealing and pressure resistance properties, protecting the internal filter element and guiding the airflow smoothly through. Usually, it has inlet and outlet interfaces, and some are equipped with pressure difference indicators (to remind of filter element replacement).

Filter element

Material: Commonly made of paper, non-woven fabric, glass fiber, or metal mesh, and different materials have different filtration accuracies (generally from several micrometers to several tens of micrometers).

Structure: Mostly folded or cylindrical, increasing the filtration area and extending the service life.

Function: Capturing solid particles and some moisture in the air through interception and adsorption, and the filtration efficiency directly affects the air intake quality.

Sealing parts

Such as rubber sealing rings, ensuring the seal between the filter housing and the filter element, as well as between the filter housing and the air intake of the air compressor, preventing unfiltered air from directly entering the system.

Auxiliary components

Some filters are equipped with protective covers (to prevent rainwater and debris from entering), drain valves (to discharge condensed water in the filter housing), or differential pressure switches (to trigger an alarm when the filter element is clogged).

II. Atlas Copco Oil Filter Components (with oil-gas separator as the core)

When the air compressor is working, lubricating oil mixes with compressed air (especially for oil-injected air compressors). The core function of the oil filter component is to separate the oil from the compressed air, ensuring that the discharged compressed air has an oil content that meets the standard (usually ≤ 3 ppm), and at the same time recovering the lubricating oil for recycling.

Main components:

Oil-gas separation tank

Metal pressure vessel, after the mixture of compressed air and lubricating oil enters the tank, it is initially separated through volume expansion, centrifugal force, etc. (coarse separation), and larger oil droplets fall to the bottom due to gravity.

Oil-gas separation filter element

Material: Multi-layer composite filter material (such as glass fiber, polyester fiber, etc.), with hydrophobic properties, capable of adsorbing tiny oil droplets.

Function: Performing fine filtration on the separated compressed air, through diffusion and interception principles, condensing micrometer-sized oil droplets into larger oil droplets and returning them to the oil tank.

Performance indicators: Separation efficiency (directly affecting the quality of compressed air), dust holding capacity (determining the service life), pressure difference (increasing when the filter element is clogged, requiring timely replacement).

Oil return system

Return oil pipe: Guiding the separated lubricating oil from the bottom of the separation tank back to the air compressor main unit (such as screw compression chamber), reducing fuel consumption.

Return oil check valve: Preventing the return of lubricating oil when the compressor stops, avoiding oil spraying during the next startup.

Safety and monitoring components

Safety valve: Automatically releases pressure when the pressure in the separation tank exceeds the limit, protecting the equipment.

Oil level mirror / sensor: Monitoring the oil level in the oil tank to ensure normal lubrication system supply of oil.
