Georgia Pest Control Practice Test

Which of the following pressures is ideal for a compressed air sprayer?

1. 5 - 10 PSI

2. 10 - 20 PSI

3. 20 - 30 PSI

4. Above 30 PSI

The correct answer is: 20 - 30 PSI

The optimal pressure range for a compressed air sprayer is typically between 20 to 30 PSI. This range provides sufficient force to effectively atomize pesticides, ensuring an even and thorough application of the product over a targeted area. When the air pressure is set within this range, it facilitates the creation of fine droplets that enhance coverage and penetration, which is crucial for the successful management of pests. Setting the pressure too low, such as in the lower ranges, may lead to poor atomization resulting in larger droplets that do not cover the surfaces adequately. Conversely, pressures above 30 PSI could cause the sprayer to create overly fine droplets that may drift away from the intended target area, reducing efficacy and potentially leading to environmental contamination. Maintaining the pressure in the 20 to 30 PSI range strikes a balance between effective delivery and safety, making it the ideal choice for pest control applications.
