The concept of wind pump
The air pump or air compressor plays a vital role in painting, especially painting with a pistol. By compressing the air, this device provides the necessary force to spray paint with high pressure and precision. In addition, I must say that you can benefit from the following benefits by choosing the best air pump for painting.
Increasing work speed and efficiency: The air pump helps you to save time and avoid wasting paint by spraying paint quickly and evenly.
< b> Improving the quality of painting: The air pump distributes the paint particles evenly and prevents the creation of scratches and unevenness on the work surface.
Possibility of painting hard-to-reach surfaces: Using different nozzles, the air pump can be used to paint hard-to-reach surfaces, such as corners, delicate angles, or objects with intricate details.
Types of wind pumps for painting
So far I have introduced you to the concept of air pump, in the following I will explain the best types of air pump for painting. Generally, two types of air pumps are used for painting.
Piston wind pump
This type of wind pump has a simple mechanism and has a better price than screw models. In a piston air pump, air is compressed by a moving piston. This wind pump is significantly cheaper than other models and due to its simple structure, it has less weight and dimensions and is easier to move. Also, the piston air pump is a suitable and economical choice for use in home painting, landscaping or small workshops. But as you know, no device is perfect. Despite the advantages I mentioned, the piston air pump has some disadvantages. For example, a piston air pump produces considerable vibration and noise due to the movement of the piston. In addition, this type of air pump requires continuous lubrication for smooth operation, which can cause air pollution and oil droplets in the paint. In addition, the piston air pump has a shorter service life compared to the screw model. Finally, I must say that this type of air pump cannot be used regularly.
Screw wind pump
The wind screw pump has a more complicated mechanism than the piston model and has a higher price. In this type of air pump, air is compressed by two spiral screws that move inside the housing. Due to the absence of a piston, the air screw pump produces very little vibration and noise, and is a suitable option for use in sound-sensitive environments, such as hospitals or residential areas. Also, the air screw pump does not need lubrication and the output air is free of oil, which is one of the important advantages of this type of air pump in painting. The air screw pump has a much longer service life than piston models due to lower wear and tear. In addition, this type of wind pump with high efficiency and low energy consumption provides economical performance.
My good friend, but as I mentioned, this type of pump has disadvantages such as the high price. In addition, due to its heavy weight and large size, it is difficult for you to move it.
The most important factors in buying a wind pump for painting
To buy the best air pump for painting, you should pay attention to the factors that we will explain below.
Tank capacity: The tank capacity is expressed in liters and It shows the amount of compressed air stored in the pump. I suggest using a tank of about 350 liters for home paintings. But for professional work, you will need a tank of about 500 liters or more.
Engine power: Engine power is expressed in horsepower or watts and indicates the pump's ability to produce compressed air. is For casual painting, a 1-2 horsepower motor is sufficient, but for heavier work, you'll need a 3-horsepower motor or more.
Air pressure: Air pressure is expressed in bar or pascal and indicates the strength of the air pressure coming out of the pump. For most painting applications, a pressure between 6 and 10 times is enough.
Flow rate: Air flow rate is measured in CFM (cubic feet per minute) and indicates how much air volume the air pump can move per minute. For normal painting, a flow rate of 10 to 15 CFM is sufficient.
Amount of noise produced: Air pumps can produce a lot of noise which can be annoying. Especially if you plan to use the pump in residential areas, look for models that produce low noise.
Portability: If you plan to move the pump regularly, Look for models that are light in weight and small in size.
