Symptom → cause → check → action
Start with trends and measurements. Replacing an element without finding the root cause often gives only a short-lived result.
Eight typical symptoms
The matrix covers baghouses and cartridge collectors, gas filters, gas turbines, filter presses, CEMS and water sensors.
- Likely cause
- Weak pulse, wet cake, high A/C or blocked discharge
- First check
- Gauge, pulse air, valves, hopper and dew point
- Action
- Remove the cause, restore cleaning, then assess the media
Signs of incorrectly selected media
Analyse the element and the duty history.
- Rapid ageing
- Shrinkage
- Hydrolysis
- Burn marks
- Blinding
- High residual ΔP
- Poor cake release
- Unstable emissions
How to start the diagnosis
- 01Trends and measurements
Collect the recent ΔP, emissions or filtrate data, the duty map and the process analysis; measure the points in the "first check" column.
- 02Documents
Attach the specification, datasheet, OEM reference, drawing, nameplate and mounting photos to the enquiry.
- 03Removing the cause
First correct the mechanical or duty cause: loading, cleaning, drainage, tightness; only then assess the media or the element.
- 04Upgrade
After auditing the housing, fan or pump, hydraulics, controls, site and actual duty, the media, compartments, pulse system, instrumentation, washing or membrane plates can be upgraded.
