Compressed air in industrial applications contains in 1Nmᶟ more than
100 million of polluting articles. Most of these particles are so
small in dimension, less than 5 micron, that they cannot be
intercepted by the standard intake filters installed in the
compressors. Such particles, mixed with water and oil vapour
generated during compression, cause the early wear and tear of the
appliances and consequently they are the cause of expensive
interruptions of the production and remarkable increase maintain.
Selection right Air Filters will allow the best choice of the suitable equipment according to
the quantity of air to be treated and the necessary filtration
degree in order to increase and improve the performances of the
whole system.

How to install Compressed Air Filter?
1. Clean the compressed air pipes and valves connected to the air
inlet and outlet of the filter before installation.
2. Adopt the combination of main pipe filtration and terminal
filtration to ensure the gas quality at the point of use.
3. When installing, the air inlet and outlet of the filter should
be kept level, and the sewage outlet should be at the bottom. A
certain space must be reserved in the vertical direction to
facilitate the maintenance of the filter and the replacement of the
filter element.
4. The filter of the screw air compressor should be installed in a
ventilated and cool place, as close as possible to the air point,
to reduce the influence of the pipeline on the quality of the
filtered compressed air.
5. Install and use within the specified working pressure and
working temperature range, and install all levels of filters in the
correct order according to the air inlet and outlet instructions or
the direction indicated by the arrow, from coarse to fine
installation. Avoid bypass as much as possible during installation.
Because the oil in the air is bypassed to the downstream of the
filter and then sticks to the inner wall of the pipeline, it is
difficult to find effective means to remove it.
6. The filter element should be replaced regularly. Carefully
record the replacement time. It is recommended that the working
time zone should not exceed 6000 hours.
7. The discharge time of the auto drain is suitable for draining
the liquid water, and the discharge interval is subject to the
water content in the pipeline;
8. Different grades of compressed air filters can be equipped with zero pressure loss floating ball drain valves or manual valves according to customer requirements.

Sources of compressed air pollutants
1. Atmosphere
Air compressors suck in and compress a large amount of atmosphere.
They continue to fill the system while bringing in extremely small
pollutants. These pollutants include: water vapor, atmospheric
dirt, dust and pollen particles, oil vapor, and microorganisms.
2. Air compressor
In addition to the pollutants inhaled from the atmosphere, the air
compressor will also mix a small amount of oil into the compressed
air flow during the air compression process. This oil may exist in
the form of liquid oil, aerosols and oil vapor. It is also worth
noting that although so-called oil-free compressors do not directly
inject oil into the airflow, they still compress the same
contaminated air like an air compressor, so any oil vapor in the
surrounding environment will still be affected. It is compressed
and enters the downstream system. After the compression stage, the
aftercooler cools the air, which can condense any water vapor and
mix it into the compressed air stream in the form of liquid water
or aerosol.
High Efficiency Removal of Pollutant
Our Medium & high pressure filter features efficiency fiber glass
and felt media to maximize the filtration of dry and wet dust,
particulates, oil suspended solids and water droplets. Minimize

Avoid Second Pollution
Inside and outside with anti-corrosion, with stainless steel manual
ball valve.
Low Differential Pressure
The optimized flow design and the use of filter materials serve to
keep differential pressure at a constant low level during the
entire service life of the element without compromising it's dirt
holding capacity.
High-tech design
It is clearly visible due to the edges at the filter head of the
compressed air inlet to ensure reliable connection between the left
and right filter housings and the left and right filter housing
parts during the assembly process.
Compressed air provides a smooth, non-turbulent air velocity when
entering the filter element.
