Core advantages of the original factory filter:
The original oil filter adopts materials and structures specially designed for compressor operation conditions:
Efficient filtering medium: Multi-layer composite filter material or glass fiber material, capable of filtering particles smaller than 5 microns, with a filtration efficiency of up to 99.9%, far exceeding that of ordinary substitutes;
Pressure-resistant and deformation-resistant housing: Capable of withstanding the oil pressure of the compressor during operation (usually 10-20 bar), preventing rupture and leakage;
Precise matching design: Interface threads and sealing ring sizes are fully matched with the model, avoiding oil leakage after installation;
Greater dirt capacity: Can accommodate more impurities without clogging, ensuring continuous effective filtration during the maintenance cycle.
Key information for model matching:
It is necessary to select the corresponding filter based on the specific model of the air compressor. For example:
Filters for the GA series (such as GA11, GA37, GA75) are different from those of the G series, ZR series;
Filters for different power models within the same series (such as GA22 and GA30) may also differ.
When purchasing, please provide:
The model of the air compressor (such as GA45VSD+), and the factory serial number (located on the equipment nameplate);
The part number on the old filter (such as 1621751400, usually engraved on the housing).
Replacement and maintenance tips:
Replacement cycle: According to the manual requirements, generally replace once every 1500-2000 hours or 6 months (whichever comes first), and shorten the cycle in harsh environments;
Replacement steps: Release the oil pressure after stopping the machine, remove the old filter with special tools, clean the installation surface, apply a small amount of oil on the sealing ring of the new filter, manually screw until the sealing ring is in place and then tighten 1/2-3/4 turns (avoid over-tightening to cause damage);
Precautions: It is recommended to replace the oil filter at the same time as replacing the oil. For new machines, replace the oil about 500 hours after the first run to remove metal debris generated during the running-in period.
