The function of replacing the Filter Element of the German 1621 1389 99 air compressor is to effectively intercept solid impurities such as dust, sand particles, and metal particles in the air through a multi-layer filtering structure, allowing clean air to enter the air compressor, avoiding impurities from entering the interior of the air compressor, reducing component wear, and lowering the probability of failure, thereby extending the service life of the air compressor and ensuring stable and efficient operation.

The 1621 1389 99 filter cartridge has the following characteristics:

-Efficient filtration: Using high-quality filter materials imported from the United States or imported fiberglass, the filtration accuracy is high, reaching different levels such as 0.1 μ m or 0.001-5 μ m, with a filtration efficiency of 98% or even 99.99%. It can effectively intercept solid impurities such as dust, sand, and metal particles in the air, and the oil content of compressed air can reach below 3ppm, ensuring the cleanliness of the air entering the air compressor.

-Structural stability: able to maintain shape under pressure and maintain maximum filtering surface area to enhance performance. Its rigid structure helps to maintain a uniform pressure difference, prevent the filter element from collapsing due to excessive pressure difference, and avoid causing the air compressor to shut down.

-Excellent material: The end cap is often made of ABS engineering plastic or aluminum alloy, which has high strength; The filter is made of 430 stainless steel, which is corrosion-resistant; The outer layer is provided with a hydrophobic foam sleeve that is oil resistant and acid resistant to chemical corrosion, so as to prevent the coalescing liquid from entering the air flow again and ensure the effect of oil and water removal.

-Long lifespan: Under normal use, the lifespan is relatively long, with some filter cartridges having a lifespan of up to 2000 hours or even 8000 hours, reducing the hassle of frequent replacement and lowering maintenance costs.

-Good adaptability: the original equipment specially designed for Atlas and other brand air compressors meets or even exceeds the performance specification requirements of the original equipment, and can be well matched with the air intake system of the air compressor to ensure stable and efficient operation of the air compressor.
