Scheduling Reference for Replacement Periods (Only for time reference, differential pressure \/ leak detection priority)<br \/>\nDaily operation for 8 to 12 hours, clean and low-dust environment, regular maintenance of initial \/ medium efficiency filters<br \/>\nHigh-efficiency recommended period: 2 to 3 years<br \/>\n24-hour continuous operation in a regular clean workshop<br \/>\nHigh-efficiency recommended period: 1.5 to 2 years<br \/>\nHigh foot traffic, slight dust generation, pre-filter frequently exceeds replacement period<br \/>\nHigh-efficiency recommended period: 1 to 1.5 years<br \/>\nII. Hard Replacement Criteria (More important than the age, any of the following immediately requires replacement)<br \/>\nThe operating differential pressure reaches twice the initial pressure;<br \/>\nPAO\/DOP integrity leak detection fails, and re-sealing still leaks;<br \/>\nThe working face wind speed continuously remains below 0.36m\/s, and the fan and pre-filter faults are excluded;<br \/>\nVisible dust blowing from the outlet and continuous excessive dust suspension particles in the workshop.<br \/>\nIII. Supplementary Explanation<br \/>\nAge is only a reference for preventive replacement. If it reaches the period but the differential pressure, wind speed, and leak detection are all qualified, it can be temporarily extended and the inspection frequency can be increased;<br \/>\nIf it is not at the age but the differential pressure rapidly rises or the leak detection fails, it must be replaced in advance.<\/p>","protected":false},"excerpt":{"rendered":"<p>I.
