Test Procedures

(1) Restriction and Differential Pressure Test – Measures pressure drop at multiple airflow rates to evaluate airflow capacity.

(2) Initial Efficiency Test – Determines the filter’s particle capture efficiency at the start of operation using A2 or A4 test dust.

(3) Full-Life Efficiency Test – Measures filtration efficiency over the complete service life until the filter reaches the final restriction.

(4) Incremental Efficiency Test – Evaluates filter performance at multiple loading stages (10%, 25%, 50% of pressure drop difference).

(5) Dust Holding Capacity Test – Calculates total dust mass retained in the filter to assess longevity and maintenance intervals.

Operation and Maintenance

(1) Install the filter securely with appropriate adapters to ensure proper sealing.

(2) Select test dust type (A2 or A4) and adjust the airflow according to the desired test protocol.

(3) Start automated test sequences via PLC + PC interface; monitor real-time airflow, pressure drop, and particle capture.

(4) Review visualized test curves and automatically generate Excel-format reports.

(5) Store historical data for long-term traceability and quality control.

(6) Perform routine cleaning, calibration, and validation of sensors and dust feeders.

(7) Remote monitoring and troubleshooting can be conducted using integrated camera and control systems.
