The paint filtration system of the HVLP Gravity Feed Air Spray Gun is one of its core components and plays a vital role in ensuring the spraying quality and paint stability.
1. Composition of the filtration system
The paint filtration system of the HVLP Gravity Feed Air Spray Gun is usually composed of filters, filter screens, pump systems, and control systems. These components work together to ensure that the paint is fully filtered and purified before spraying.

2. Working principle
a. Paint entry
The paint first enters the inlet of the paint filter through the pipeline. During this process, large particles of impurities and particulate matter in the paint are initially intercepted, reducing the burden on subsequent filters.
b. Filter filtration
The paint that has been initially filtered enters the filter screen inside the filter. The filter screen uses a precision metal screen or liquid filter element. According to the characteristics of the paint and the spraying requirements, filters of different precisions can be selected. When the paint passes through the filter screen, solid particles and impurities are intercepted on the filter screen, and the clean paint passes through the filter screen to the next processing stage.
c. Multi-stage filtration
In order to improve the filtering effect, the paint filtration system can also adopt a multi-stage filtration design. The paint that has been initially filtered enters the higher-precision filter again for filtration under the action of the pump system to ensure that the tiny particles and impurities in the paint are completely removed.
d. Control system
The control system is responsible for the operation and adjustment of the entire paint filtration system. By setting parameters such as filtration time and filtration accuracy, the control system can ensure the efficient operation of the paint filtration system. At the same time, the control system can also monitor the status of the paint filter, such as the clogging of the filter, and promptly remind the user to clean and replace it.

3. Filtration effect
After filtration and purification by the paint filtration system, solid particles, impurities and particulate matter in the paint are effectively removed, ensuring the quality and stability of the paint. This can not only improve the spraying effect, but also extend the service life of the spraying equipment and reduce maintenance costs.

4. Cleaning and maintenance
In order to maintain the normal operation and filtering effect of the paint filtration system, users need to clean and replace the filter regularly. When cleaning, you can use a cleaning agent or clean water to rinse the filter, and then dry it and reinstall it. When the filter is damaged or the filtering effect decreases, you need to replace it with a new filter in time.
