Product Description

The higher the accuracy of screw air compressor oil filter, the better?
The main function of oil filtration is to remove impurities from oil. Most customers may think that the higher the accuracy of the oil filter, the better the filtration effect, but they worry that the filtration accuracy is too high, easy to plug. In fact, this perception is wrong.
The experiment shows that there is some relationship between the filtration accuracy of the oil filter and the filtration effect, but the real decision of the filtration effect is not the filtration accuracy, but the adsorption capacity of the oil filter paper. The larger the amount of dust, the stronger the adsorption, the better the filtration effect. Fiber filter paper filtration effect is good, because of the large dust capacity, strong adsorption capacity, strong carbonization resistance.

The most important part of the air compressor is the oil filter. A good oil filter can remove the impurities in the air compressor oil in time to ensure the normal use of the air compressor. Air compressor oil filter is a device used to filter oil, is a kind of wear parts.
The role of air compressor oil filter: filter out the metal particles and impurities in the air compressor lubricating oil, ensure the cleanliness of the oil circulation system and protect the safe operation of the main engine.
The harm of overdue use of air compressor oil filter:
1, insufficient oil return, resulting in high exhaust temperature, shorten the service life of oil and oil core; Lead to insufficient lubrication of the main engine, seriously shorten the life of the main engine;
2. After the filter element is damaged, the filtered oil containing a large number of metal particle impurities enters the main engine, resulting in serious damage to the main engine.


Air compressor regular replacement of 3 filter is in order to air compressor function normal and stable work, to meet the action requirements of gas components.
The role of the 3 filter and oil of the air compressor in the use of the air compressor is:
1, the air filter mainly filters the dust in the air (intake). If the air intake quality is not replaced for a long time, the oil filter, oil, and lubricating oil will be shortened. When the lubricating oil deteriorates, the body will be stuck. Moreover, if the air filter is blocked, the gas production of the air compressor will be reduced.
2. The oil filter mainly filters the impurities in the lubricating oil, which affects the life of the lubricating oil without replacement for a long time. If the oil filter is blocked, it will cause the oil circuit circulation is not good, and the machine will be high temperature and severe because of the lack of oil.
3, the main role of oil is to filter the oil in the oil mixture, to ensure that the compressed gas contains less oil. Make the compressed gas clean. When the oil is not distributed well, it will cause oil consumption. Oil plugging will cause the running current of the air compressor to be too large, and the machine will not be able to open in serious cases.
4. Lubricating oil plays 4 roles in the operation of air compressor. Lubrication, sealing, cooling, noise reduction.

How does the horsepower of an air compressor affect its capabilities?

The horsepower of an air compressor is a crucial factor that directly impacts its capabilities and performance. Here’s a closer look at how the horsepower rating affects an air compressor:

Power Output:

The horsepower rating of an air compressor indicates its power output or the rate at which it can perform work. Generally, a higher horsepower rating translates to a greater power output, allowing the air compressor to deliver more compressed air per unit of time. This increased power output enables the compressor to operate pneumatic tools and equipment that require higher air pressure or greater airflow.

Air Pressure:

The horsepower of an air compressor is directly related to the air pressure it can generate. Air compressors with higher horsepower ratings have the capacity to produce higher air pressures. This is particularly important when operating tools or machinery that require specific air pressure levels to function optimally. For example, heavy-duty pneumatic tools like jackhammers or impact wrenches may require higher air pressure to deliver the necessary force.

Air Volume:

In addition to air pressure, the horsepower of an air compressor also affects the air volume or airflow it can provide. Higher horsepower compressors can deliver greater volumes of compressed air, measured in cubic feet per minute (CFM). This increased airflow is beneficial when using pneumatic tools that require a continuous supply of compressed air, such as paint sprayers or sandblasters.
