In order for any liquid to be sprayed, it must be dispersed with air or the liquid must be pressurized.
In air-shattering nozzles, the pressure of the liquid's own flow is sufficient. Even if the liquid comes in drops, the air can break up this liquid and spray it. Especially in processes where very little liquid needs to be applied (for example: 0.01 gr), an air fragmentation nozzle should be preferred. With the pressure of the air and liquid, the particle size can change and different spray patterns can be obtained. Air fragmentation nozzles should be preferred in applications such as humidification, dust precipitation, lubrication, etc.
Nozzles, which spray only with the pressure of the liquid, offer a constant spray depending on their hole diameter and the structure of the head. Particularly dust is undesirable, washing, cooling, etc. They are preferred in applications.
The nozzles that are especially preferred as water spray nozzles are those where the mains pressure is sufficient. 2-3 bar liquid pressure will be sufficient to split the water at the desired rate.
In liquid spraying methods, there are nozzles that work with high pressure (250 bar). These nozzles, which are especially preferred in paint applications, do not create dust and save paint.
