The BOLL Differential Pressure Indicator is a robust and compact device indicating the contamination level of the filter elements. The differential pressure between filter inlet and filter outlet is the measurable indicator for the contamination degree of the filter element. When the preset maximum value of differential pressure is reached, the filter needs to be cleaned.
