A few things you need to know about paint filter paper
As paint filter paper is often mentioned in dry spray paint rooms, people are curious about what filter paper is and its function. Then the following article will guide you to have a clearer understanding of paint filter paper.
Paint filter paper mainly includes V-type and Multi-layer paint filter paper. Next, we will take you to a deeper understanding through this article.
Paint filter paper is an environmentally friendly filter material specially used in dry spray booths. Through its efficient filtering ability, improvement of the working environment, convenience of use and safety guarantee, it provides an efficient, environmentally friendly, and safe solution for the spraying industry.
Its main functions include:
A. Effective filtration: It can effectively filter a variety of fluids such as paint, oil, plastic, dye, coating, etc., with a filtration effect of up to 99.99%. This efficient filtering ability prevents paint and other fluids from causing pollution during the spraying process, protecting the environment and the health of operators.
B. Improve the working environment: By allowing the paint mist to accumulate at different levels under the action of the airflow, the purpose of separating and adsorbing toxic air and substances is achieved, thereby improving the environment of the spraying workplace, reducing the release of harmful substances, and improving the air quality of the working environment.
C. Easy to use: When the paint filter paper reaches saturation, it can be directly removed and replaced with a new paint filter paper. The operation is simple and quick, and does not require complicated cleaning or maintenance processes, saving time and cost.
D. Safety guarantee: It has good air permeability uniform precision and stability, and is not prone to leakage, thus ensuring safety during use.
In addition to being used in paint booths and automotive spraying, paint filter paper can also be used in any place where spraying is required. When the working environment requirements of the spray booth are strict or the humidity is high, the use effect is still very well.
PART Ⅰ: About V-type paint filter paper
The working principle of paint filter paper is mainly based on the principle of inertial separation. As shown in the figure below, it allows the paint mist to effectively absorb the over-spray beyond the range under the action of airflow and forces the over-spray flow to change direction multiple times, so that the particles heavier than air will adhere to the paper wall and will not be carried away by the airflow.
- The wrinkled structure can effectively absorb overspray within a certain range and can bear at least 15 kg per square meter, which is 3 to 5 times the load-bearing capacity of other types of filter paper.
- Moreover, it is deep load-bearing rather than surface load-bearing and has a higher paint capacity. This design not only exceeds the life of other types of filter paper but also plays a role in equalizing the flow, effectively improving the environment of the paint-spraying workplace.
- When the paint filter paper is saturated, remove it and replace it with a new paint filter paper, it can be used immediately, which is simple, fast, and environmentally friendly.
(1) High performance: low wind resistance, dust holding capacity is 3-5 times that of paint mist cotton, long operating time (usually 500-860 hours), and the air flow is not greatly affected when the dust holding capacity is saturated.
(2) Environmental protection and pollution-free: using environmentally friendly materials to reduce pollution to the environment, it can also effectively absorb overspray beyond the range, prevent the spread of paint mist and odor, and improve the environment of the paint spraying workplace.
(3) Strong applicability: suitable for various paint spraying working environments, including environments with high humidity, ensuring the smooth progress of paint spraying.
(4) High stability: with good continuous airflow stability, it ensures the stability of spraying conditions, which is conducive to controlling the spraying quality and surface quality.
(5) Easy to transport: foldable, easy to transport and install;
In summary, paint filter paper provides great convenience and environmental protection for paint spraying through its high-performance filtration, environmental protection, low cost, and simple installation.

PartⅡ: About multi-layer paint filter paper:
The working principle of multi-layer paint filter paper is to use the influence of air pressure on airflow. When the paint mist in the spray paint room or paint baking room flows to the multi-layer paint filter paper under the action of air pressure, the filter paper will be affected by the air pressure and blown open naturally. The filter paper with increasing density layer by layer is like a multi-layer filter screen that hinders the flow of paint mist, intercepts the scattered paint mist during the spray painting operation, and effectively absorbs the paint and dust in the air.
(1) Intercept scattered paint mist: During the painting operation, the laminated paint mist paper filter can effectively intercept the scattered paint mist, thereby controlling air pollution.
(2) High filtration performance: The laminated paint mist paper filter has efficient filtration and can effectively remove paint mist, ensuring the quality and effect of the painting operation.
(3) Fire retardant and antistatic: The filter has the characteristics of fire retardant and antistatic, which can ensure the safety of the painting operation.
(4) Less resistance loss and avoidance of secondary pollution: The laminated paint mist paper filter has less resistance loss, which can avoid secondary pollution and ensure the environmental hygiene of the painting operation.
(5) Simple replacement and clean workplace: The replacement process of the filter is simple and convenient, and it can keep the workplace clean and tidy.
(6) Good economic performance: low cost.
