Dust Collector Troubleshooting

Are you having problems with your dust collector? Troubleshoot your dust collector now.

Is your dust collector showing signs of trouble ahead?   Keeping your dust collector healthy will prevent unscheduled down time, production loss, or a costly shut-down. Here are some of the common indicators your dust collector is having issues, and how you can troubleshoot them.

High Pressure Drop

Dust collector troubleshooting

  1. Check timer indicator lights to see if it is functioning properly and pulsing the valves. Replace fuse or timer.
  2. Check air pressure line regulator for proper pressure and leaks. Maintain 80 to 90 psi in header.
  3. Check hopper discharge and 55 gal drum lid for leaks allowing re-entrainment of dust. Repair seal or joints if leaking.
  4. Check differential pressure lines (tubing) for plug or breaks allowing faulty readings.
  5. Moisture in the dust causes a hard dense cake, which may blind the filter media.
  6. Check air supply for clean dry, oil-free air. Faulty air systems will coat the filter on the inside and blind the filter causing high-pressure drop and premature replacement. Always maintain clean dry air for the cleaning system.

Attempt to dry the tubes by circulating clean warm air through the collector and going through several cleaning cycles. Empty the hopper. Check the process to prevent condensation. If Nanofiber cartridges are exposed to high moisture, water or liquids of any kind they may need to be replaced.

A Reduction in Pressure Drop Accompanied by a Dirty Exhauster Output
  1. One or more filters may have holes in them or have damaged seals. Perform colored fluorescent die test to identify, if possible. Repair/replace, as necessary.
Continued Drain on Air Supply
  1. A solenoid valve may be stuck open or a diaphragm may be ruptured.

This can be detected by listening to each valve at the unit for constant airflow noise. Inspect rubber diaphragms and or solenoid seals and replace as needed. Open top doors and identify which blow pipe the air is flowing from. In turn this will identify the failed valve or solenoid assembly. Inspect diaphragm valve for failed diaphragm or small particle seated on diaphragm. Clean or replace as warranted.
