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 choose right filter for Your Air Compressor System?
When you’re working with air compressors, air purification and filtration is an critical part of maintenance. Compressed air filters play an important role in your industrial air compressor
system. Choosing the right filter not only increases the efficiency
of your unit, but it can also reduce energy costs and protect your employees from harmful chemicals and
particulates.
However, does all air filter work for your compressed air system? Well it is
depending on your working conditions, the project you’re completing and how often you use your
equipment, you’ll need to make an precise choice. This guide will detail how air compressor filters work,
why they’re important, what type of Air Compressor Filter to buy and when you should replace it.

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.
