How can a fume extraction system detect a clogged filter before airflow performance is significantly affected? This article explains how pressure switches, vacuum switches and differential pressure monitoring can be used for filter condition monitoring, maintenance alerts and condition-based maintenance in industrial and OEM systems.
Most systems do not fail suddenly. Filters clog gradually, pumps lose efficiency over time, and vacuum systems drift out of specification long before a fault alarm appears. In many cases, the earliest warning sign is not temperature, vibration, or power consumption – it is a subtle change in differential pressure (ΔP). This article explains why Differential Pressure is one of the most valuable indicators of developing failures, how Pressure Switches, Vacuum Switches, and Differential Pressure Switches are used for early fault detection, and why the most important parameter in your system may not be pressure itself, but the small change that appears long before the failure becomes visible.

Fume extraction systems depend on consistent airflow to effectively capture and remove contaminants. Over time, however, filters within the system accumulate particles and become clogged, reducing airflow and potentially creating safety risks. This is where vacuum switches prove invaluable.
