Main point
Online and offline describe whether the relevant filtering section remains in service during cleaning. The label alone does not describe the complete cleaning mechanism or establish which arrangement suits a particular dust.
Information to record
Request a sequence diagram showing filtration, isolation where provided, cleaning and return to service. Identify which valves and instruments confirm each step. Ask what filtering area remains available during the proposed sequence and which production cases the design covers.
Review and acceptance
Compare proposals using the same process duty. Keep claims about cleaning intensity separate from airflow capacity and outlet acceptance. The commissioning plan should verify the documented sequence and its feedback signals without importing another machine's timing values.
FAQ: Is offline cleaning always better?
Selection depends on the complete process and equipment design, not on the label alone.
FAQ: Can cycle times be copied from a similar collector?
Use the approved sequence and supplier requirements for the actual installation.
