What type of application equipment uses pressure to deliver spray?

The type of application equipment that uses pressure to deliver spray is the compressed air sprayer. This equipment utilizes air pressure generated by a pump to force the liquid pesticide through the nozzle, creating a fine mist or spray. This method allows for more controlled and targeted application, ensuring that the pest control substances are evenly distributed over the desired area.

Compressed air sprayers are particularly effective for reaching difficult spots and for applications that require a high degree of precision. The pressure created is essential for atomizing the liquid into smaller particles, which improves coverage and enhances the effectiveness of the treatment.

Other types of sprayers may utilize different methods for delivering the spray. For example, a gravity-fed sprayer relies on the force of gravity to move the liquid from a reservoir to the nozzle, and handheld sprayers may operate through manual pumping without using significant pressurization. Low-pressure sprayers typically operate at a lower pressure than compressed air sprayers, which limits their ability to produce a fine mist suitable for many pesticide applications.
