What is fog nozzle vs automatic nozzle?

A fog nozzle and an automatic nozzle are two different types of nozzles used for different purposes. Here's a comparison between the two:

Fog Nozzle: A fog nozzle, also known as a fogging nozzle or misting nozzle, is designed to create a fine mist or fog-like spray pattern. It atomizes the liquid into tiny droplets, typically ranging from 20 to 200 microns in size. Fog nozzles are commonly used for applications such as cooling, humidification, dust suppression, firefighting, and special effects.

Key features of a fog nozzle include:

Atomization: Fog nozzles are designed to produce a high-density fog by breaking the liquid into small droplets. This is achieved through specific nozzle designs, such as spiral or deflector-type nozzles, which create turbulence and shear forces to break up the liquid.

Adjustable Spray Pattern: Fog nozzles often offer adjustable spray patterns, allowing the user to change the angle and shape of the fog spray. Common patterns include narrow cone, wide cone, or fan-shaped patterns, providing flexibility in targeting specific areas or achieving desired coverage.

Flow Control: Fog nozzles provide control over the flow rate of the liquid being sprayed. This allows the user to adjust the intensity or volume of the fog to meet the application requirements.

Automatic Nozzle: An automatic nozzle, also referred to as an automatic shut-off nozzle, is designed to control the flow of liquid and automatically shut off when a predetermined level is reached. These nozzles are commonly used for fuel dispensing at gas stations or other fluid transfer applications.

Key features of an automatic nozzle include:

Auto-Shutoff Mechanism: Automatic nozzles are equipped with an auto-shutoff mechanism that stops the flow of liquid when the target level is reached. This prevents overfilling, spillage, and wastage of the liquid.

Flow Control: Automatic nozzles offer control over the flow rate to regulate the speed and volume of the liquid being dispensed. The flow rate can often be adjusted using a lever or trigger mechanism.

Safety Features: Automatic nozzles incorporate safety features to prevent fuel spills or leaks. Some models require continuous pressure on the lever or trigger to keep the flow of liquid active. If the pressure is released, such as when the nozzle is dropped or released, the flow is automatically shut off.

In summary, a fog nozzle is used for creating a fine mist or fog-like spray pattern, while an automatic nozzle is used for controlled liquid dispensing with an auto-shutoff feature. They serve different purposes and are designed to meet specific application requirements.
