I. Core Functions and Synergistic Relationship of Air Filter and Oil Filter
Air Filter Component: Filters dust and particles in the atmosphere entering the air compressor (typically with a filtration accuracy of 1-5 μm), preventing impurities from entering the compression chamber and avoiding wear of precision components such as the rotor and bearings, while reducing the burden on the subsequent oil-gas separation system.
Oil Filter Component: Filters metal debris, oil sludge, carbon compounds, etc. in the circulating lubricating oil (with a filtration accuracy typically of 3-10 μm), protecting the lubrication effect of moving parts such as bearings and gears, and preventing wear or system blockage caused by oil contamination.
The combination of these two components can significantly reduce equipment failure rates, extend the lifespan of the main unit, and ensure the quality of compressed air and the service life of the lubricating oil.
II. Typical Composition of Oil Filter Component
Oil Filter Element: The core filtering component, using multiple layers of filter materials (such as glass fiber, metal mesh, etc.), with efficient filtering capabilities and a certain capacity for pollutant absorption, and the specifications need to be matched according to the model (such as 2901053500, 2901066800, etc., common models).
Filter Housing / Base: Made of metal, used to fix the filter element, usually equipped with a bypass valve (automatically opens when the filter element becomes clogged beyond the set pressure difference to avoid interruption of oil supply).
Sealing Element: Such as rubber sealing rings, ensuring that the oil passes through the filter element for filtration completely, preventing unfiltered oil from directly entering the lubrication system.
III. Selection and Maintenance Key Points of Air Filter and Oil Filter Combination
Adaptability Principle: Must select original factory or certified matching filter elements according to the specific model of the air compressor (such as GA series, G series, etc.), avoiding equipment damage due to size mismatch or insufficient filtration efficiency.
For example: The GA75 model may be paired with air filter 1621475200 and oil filter 2901053500.
Replacement Cycle Synergy:
Air Filter: In dusty environments (such as factory workshops), it is recommended to replace every 1000-2000 hours; in clean environments, it can be extended to 3000-4000 hours, depending on the alarm of the pressure differential indicator.
Oil Filter: Generally replaced synchronously with the lubricating oil (usually every 2000-4000 hours), or according to the requirements of the equipment manual to avoid failure of the filter element due to oil contamination.
