Air Compressor Three Filter Elements for Screw Air Compressor Replacement
Introduction:The air compressor three filter elements are core consumable parts for screw air compressors, including oil separator filter, air filter cartridge and lubricating oil filter. These replacement filters can replace famous international brands such as Atlas Copco, Fusheng, Kaeser, Sullair, CompAir and Ingersoll Rand. They are widely used in power, petroleum, pharmaceutical, textile, chemical, metallurgy and machinery processing industries. Matched with Dust Collector Filter and Air compressor filter, they provide reliable filtration protection for the whole air compression system.

Product Introduction
Our air compressor three filter series are specially designed for screw air compressor maintenance and replacement. Together with Dust Collector Filter and Air compressor filter, they form a complete air purification and compressor protection system. This product line covers three key consumables: oil separator filter element, air filter cartridge and lubricating oil filter. We adopt high-performance filter media imported from HV and Lydall of the United States. The filters are compatible with multiple mainstream international screw compressor brands, including Atlas Copco, Fusheng, Kaeser, Sullair, CompAir and Ingersoll Rand. Stable filtration performance, long service life and cost-effective replacement make them popular in power, petroleum, pharmaceutical, textile, chemical, metallurgy, transportation, environmental protection and machinery manufacturing fields.
Working Principle
Oil Separator Filter Element
The oil separator filter adopts ultra-fine glass fiber composite filter media. When the oil-gas mixture from the compressor flows through the filter layer, the oil mist particles are captured, coalesced and separated. The gathered lubricating oil flows back to the oil tank through the secondary oil return pipe, while clean compressed air is delivered out. It controls the residual oil content of compressed air and protects the downstream air pipeline and post-treatment filters.
Air Filter Cartridge
It intercepts dust, sand and solid impurities in the intake air, preventing abrasive particles from entering the compressor host and avoiding wear of the rotor and bearing.
Lubricating Oil Filter Element
It filters metal debris, carbon deposits and impurities inside the circulating lubricating oil, keeping the oil clean to reduce friction and wear of the compressor host.
Product Performance & Parameters
Oil Separator Filter Element
Filter media: Composite ultra-fine glass fiber from HV and Lydall, USA
Residual oil content in compressed air: 3~6 PPM
Oil mist particle control: ≤0.1 μm
Service life: 3500 ~ 5200 hours
Initial pressure drop: ≤ 0.02 MPa
Notes for normal operation:
The oil level inside the oil separator tank shall be kept at 1/2 ~ 2/3 of the oil sight glass.
Keep the secondary oil return pipe and check valve unblocked and installed in the correct position.
Adjust exhaust pressure to the rated value.
Ensure normal operating temperature and reliable pressure maintaining valve.
Air Filter Cartridge
It is the first protection barrier of the air compressor. It removes dust and solid particles from ambient air, effectively extending the service life of the oil separator and oil filter, and reducing host wear. Different dust holding capacity grades are available for heavy dust or clean workshop environments.
Lubricating Oil Filter Element
It continuously cleans the circulating lubricating oil, removes wear debris and oxidation sediments. Stable oil cleanliness ensures the lubrication and cooling effect of the screw rotor, reducing the failure rate of the air compressor.
Core Advantages

Application Scope
Power station air compressor station
Petroleum and chemical industry instrument air supply
Pharmaceutical, food and textile factory compressed air system
Metallurgy, mining, transportation and engineering machinery supporting air compressors
General machinery processing, spraying, pneumatic equipment supporting screw air compressors
Environmental protection industry pneumatic control and air supply system
Installation & Maintenance Guidance
Replace the three filter elements according to the maintenance cycle recommended by the compressor manual.
Check the pressure drop regularly. When the differential pressure exceeds the limit, replace the filter in time to avoid energy consumption rise.
For oil separator elements, check the oil return pipeline after installation to prevent oil return blockage leading to high oil content.
Replace the air filter in advance if the working environment has heavy dust.
Replace the oil filter together with the lubricating oil during oil change.
FAQs
Q1: What does air compressor three filters refer to?
A: They refer to oil separator filter element, air intake filter cartridge and lubricating oil filter element, which are three core consumables for screw air compressors.
Q2: Can these filter elements replace Atlas Copco original filters?
A: Yes, our three filter series are developed as replacement parts for Atlas Copco, Fusheng, Kaeser, Sullair, CompAir and Ingersoll Rand compressors.
Q3: What will happen if the oil separator element is not replaced on time?
A: The residual oil content of compressed air will rise sharply, which will pollute downstream filters and pneumatic equipment, and may cause oil carryover failure.
Q4: What is the main factor affecting the service life of the oil separator filter?
A: Lubricating oil quality, working temperature, dust content of intake air and normal oil return pipeline condition.
Q5: Do I need to replace all three filters at the same time?
A: It is recommended to replace them together during regular overhaul. In some cases, single replacement can be carried out according to the differential pressure and actual condition.
