Hydraulic atomizing nozzles and pneumatic atomizing nozzles are two common types of atomizing nozzles, and there are some differences in their working principles and applicable scenarios. Before understanding the difference between them, let’s clarify the definition of an atomizing nozzle.

Definition of hydraulic atomizing nozzle

A hydraulic atomizing nozzle is a device that atomizes a liquid at low pressure without the use of any gas.

Definition of pneumatic atomizing nozzle

A pneumatic atomizing nozzle is a device that atomizes a liquid through a gas.

Advantages and disadvantages of hydraulic atomizing nozzles and pneumatic atomizing nozzles

Advantages and disadvantages of hydraulic atomizing nozzles


Hydraulic atomizing nozzles are often used in industrial processes where liquids need to be atomized into tiny droplets.

Disadvantages:

Requires high cost investment and complex layout;
Due to the small hole size, clogging problems are prone to occur.

Advantages :

No need for compressed air;
The design is relatively simple and easy to maintain.
Advantages and disadvantages of pneumatic atomizing nozzles
In many industrial processes, the spraying of fine liquid droplets is achieved through air-assisted atomizing nozzles, in which compressed air provides the liquid with the energy required to cause the droplets to spray a certain distance from the nozzle.

pneumatic atomization systems have two inherent disadvantages:

Disadvantages:

Narrow internal passages require adequate filtration of air and liquids;
High velocity jets will only produce a narrow angle spray. To solve this problem, multi-hole nozzles can produce a diffuse spray, resulting in better droplet distribution.

Advantages:

The droplets produced are extremely small;
A wide range of accessories are available for every application.
