What are the effects of poor air filters on engines?
- Oct 25, 2018 -

Air filter is an important part in the maintenance of air compressor. However, there are many brands of air filter on the market, the quality is uneven, many people in order to get cheap, buy products of poor quality, then what is the impact of poor quality air filter on the engine?


  1. Spot welding replaces seam welding at the welded parts of the shell of air filter, which can not guarantee the sealing and form a short circuit, thus causing damage.

  2. The metal parts such as the end cap of the filter element, the central pipe and the outer shell do not carry out anti-rust treatment, resulting in metal corrosion and impurities, making the filter a pollution source, and even more, replacing the adhesive with cement, which is more harmful.

  3. Using low-cost filter paper to make filter element, because of its large aperture, poor uniformity and low filtration efficiency, it can not effectively remove harmful impurities from the engine, resulting in early engine wear.

  4. The material of the central pipe of the oil filter is thin instead of thick, and the strength is not enough. In the course of using, because the central pipe is sucked out and the filter core is broken and blocked the oil circuit, the lubrication of the engine is insufficient; or the reliability of the bite is poor, and the bite is pulled open during using, resulting in a large amount of oil leakage in a short period of time, thus causing tile burning and shaft holding.

  5. The use of low-quality adhesives, and the use of very little, neither oil-resistant, and can not be firmly bonded, resulting in short-circuit filter element bonding; or filter element joint using staple connection, can not seal and short-circuit, so that a large number of harmful impurities into the engine, reduce engine life.

  6. By replacing oil-resistant rubber parts with ordinary rubber parts, engine wear and tear at early stage, life reduction or expansion deformation of external seals caused by internal short circuit of filter caused by seal failure of internal seals, resulting in the extrusion of outer seal ring of oil filter, a large amount of oil discharged in a short time, so that the engine burns tile and holds shaft. Suffer serious damage.

MANFEITE filter uses imported top filter paper for high filtration accuracy. High strength steel plate and sandblasting are used to make the bonding more firm. The use of top adhesive and the use of automatic injection machine processing, with higher stability. The use of high strength steel plate, and the use of spiral processing technology, higher support strength, can withstand 5bar differential pressure. The high mature technology with multiple tests can be applied to 5-10bar working pressure. The graphite gasket has better sealing and electrical conductivity.
