What is the top gravity cup design of the TM136 Gravity Feed Airbrush?

The top gravity cup design of the Gravity Feed Airbrush has been widely used in the field of spraying. Compared with suction-up or side-suction airbrushes, gravity airbrushes rely on gravity to naturally feed the paint into the nozzle, which makes it particularly good at fine, low-pressure spraying work. The following will introduce the principles, advantages and effects of this design on the spraying effect in detail.

1. Design principle of the top gravity cup of the gravity airbrush
The core of the design of the gravity airbrush lies in its top gravity cup. Traditional suction-up airbrushes usually require higher air pressure to absorb the paint in the cup, while gravity airbrushes cleverly use gravity to allow the paint to flow naturally into the nozzle by gravity. During operation, air enters from the air inlet of the airbrush and mixes with the paint when passing through the nozzle to form a fine spray.
The position of the top gravity cup is usually set above the airbrush, which allows the paint to flow easily with the help of gravity without the need for additional air pressure to absorb it. This design enables the airbrush to work at a lower air pressure while also being able to greatly control the spraying accuracy. Therefore, the design of the top gravity cup is particularly popular in areas that require a high degree of control, such as fine art creation, model spraying, and makeup.

2. Advantages of the gravity cup design
Improve spraying accuracy: The design of the gravity airbrush enables fine operations at low pressure. Since the pigment flows naturally into the nozzle under the action of gravity, there is no need to rely on air pressure to push the pigment, which allows the airbrush to achieve a very delicate spraying effect with a lower air pressure. This advantage is very significant for work that requires precise control of the amount of pigment, such as drawing tiny details or gradient effects.
Reduced air pressure requirements: Traditional suction-type airbrushes require higher air pressure to absorb and push the pigment, which can easily lead to uneven spraying or excessive paint. The design of the top gravity cup effectively reduces the demand for air pressure, allowing the airbrush to maintain a stable spraying effect at a lower pressure, which is very important for work that requires delicate spraying.
High pigment utilization: The gravity airbrush allows the pigment to flow naturally through gravity, and the pigment almost completely enters the nozzle and air flow. This greatly improves the utilization rate of pigments and reduces waste. Especially in work with expensive or small amounts of pigments, gravity airbrushes are more economical.
Easy to clean and maintain: The design of the top gravity cup makes the internal structure of the airbrush relatively simple, which not only reduces the chance of pigment clogging inside the airbrush, but also makes the cleaning and maintenance of the airbrush more convenient. Since the pigment enters the nozzle directly through gravity and the channel is short, it is only necessary to simply clean the residual pigment in the cup, saving operation time and energy.

3. Capacity and application scenarios of gravity cups
The capacity of gravity cups is usually small, suitable for fine spraying work. The common capacity ranges from 2ml to 15ml, and is selected according to different spraying needs. Smaller gravity cups are very suitable for small spraying jobs that require frequent color changes, such as art painting, model making, etc. Larger capacity gravity cups are suitable for occasions that require long-term continuous work, such as large-area spraying or complex gradient effects.
Gravity airbrushes are particularly suitable for work that requires high-precision control and delicate operation. For example, in the process of model making, gravity airbrushes can help users achieve very detailed details and gradient effects, making the model surface smoother and the color transition more natural. In the field of makeup, gravity airbrushes are widely used to spray foundation, blush, etc., which can evenly cover the skin and bring a light and natural makeup effect.

The top gravity cup design of the gravity airbrush makes full use of the advantages of natural gravity, making it outstanding in fine spraying, low-pressure operation and pigment utilization. This design makes the gravity airbrush an ideal choice for art creation, model making, makeup and other fields. Although it is limited in spraying large areas, its advantages in precision and economy make it the tool of choice for many professionals.
