The ___________ plate causes the air to spin inside the filter bowl.

The deflector plate is specifically designed to create a swirling motion in the air as it enters the filter bowl. This spinning action helps to enhance the separation process by forcing larger particles and contaminants to hit the walls of the bowl and drop to the bottom, where they can be collected and removed. The deflector essentially increases the efficiency of the filtration system by ensuring that more impurities are captured as the airflow is redirected and disturbed in a controlled manner. This feature is essential in maintaining the overall effectiveness and longevity of pneumatic systems by preventing contaminants from entering the downstream components.

Utilizing a deflector plate improves the performance of the filter by promoting better air quality and system reliability, which is crucial in applications where clean air is necessary for operation.
