        Whenever a customer calls us because “the dust collector isn’t working,” our first response is usually another question: “What exactly is the system doing?.” <\/strong>Rather than immediately looking at the filters, start by identifying the symptom.<\/p>

        The First Thing to Check: Differential Pressure<\/a><\/h2>\t\t\t\t<\/div>\n\t\t\t\t

        If there is one measurement every maintenance technician should understand, it’s differential pressure.<\/p>

        \"Differential

        Just as blood pressure indicates the health and efficiency of the circulatory system, differential pressure provides a vital measurement of how well the dust collector is functioning.<\/p><\/div>

        Differential pressure<\/a> (often called DP) measures the resistance to airflow across the filters.<\/strong> As dust accumulates on the surface of the filters, airflow becomes more difficult, causing the differential pressure to increase. After the cleaning system pulses the filters, the dust cake is partially removed and the differential pressure decreases.<\/p>

        This continual rise and fall is perfectly normal. In fact, a dust collector operating with some filter cake generally filters better than one with perfectly clean filters.<\/p>

        The important question you should ask yourself is: “How is the differential pressure changing over time?” <\/strong>The trend often reveals far more than a single reading ever could.<\/p>

        Understanding Differential Pressure Trends<\/a><\/strong><\/span><\/h3>

        A high differential pressure means the fan is working harder to pull air through the collector. As resistance increases, airflow usually decreases, reducing dust capture at the process equipment.<\/p>

        Before ordering replacement filters, work through the following 4-step checklist.<\/p>

        Step 1: Verify the Reading<\/strong><\/span><\/h3>

        Believe it or not, the differential pressure gauge itself is frequently the problem.<\/p>

        If operators have incorrect readings it could result in damage to the system, increase emissions, or even fire and combustible dust hazards<\/p><\/div>
