Enter your dust collector information and dust properties to calculate the required explosion vent area and review a recommended Explosion vent configuration.
Required Vent Area
See the calculated vent area for your vessel.
Recommended Vent Setup
Review panel type, size, quantity, and total vent area.
Downloadable Report
Save your inputs and calculation results as a PDF.
Have the following information ready if available. Once you have it, the calculation can be completed in just a few steps.
Vessel Information
- Dust collector or cyclone configuration
- Vessel and hopper dimensions
- Filter section information, if applicable
Dust / Design Properties
- Kst
- Pmax
- Pstat
- Pred
Looking for example Kst or Pmax values? GESTIS-DUST-EX provides published dust-explosion test data for many materials and can be used as a reference to understand typical values.
Reference only: dust properties can vary by sample, particle size, moisture, and test conditions. Use project-specific tested or otherwise verified data for the final calculation.
Choose Your Vessel
Select the dust collector or cyclone configuration that best matches your equipment.
Enter Dust Properties
Enter the tested dust properties and design pressure values used for the calculation.
Enter Dimensions
Enter the required vessel, hopper, and filter-section dimensions for the selected configuration.
Calculate & Review
Run the calculation, review the recommended vent setup, and export the report for your records.
Which vessel configuration should I choose?
Case 1 — Cylindrical, With Filter Section
For cylindrical dust collectors with a hopper and both dirty-air and clean-air sections.
Case 2 — Cylindrical, Dirty Air Only
For cylindrical vessels such as cyclones with a conical/hopper section and no filter section.
Case 3 — Rectangular, Top Clean Area
For rectangular dust collectors with a hopper and a top clean-air/filter section.
Case 4 — Rectangular, Side Clean Area
For rectangular dust collectors with the clean-air/filter section arranged on the side.
What do Kst, Pmax, Pstat, and Pred mean?
Kst (bar·m/s)
Dust explosion severity value obtained from dust testing.
Pmax (bar)
Maximum explosion pressure for the tested dust.
Pstat (bar)
Static pressure inside the system during normal operation.
Pred (bar)
Reduced explosion pressure with venting used for the calculation.
For reference, you can review published dust-explosion test data in GESTIS-DUST-EX.
Do not assume a database value represents your specific dust. Use project-specific tested or otherwise verified data for the final calculation.
Vent styles and additional options
You can also select the measurement unit, indicate whether filters are present, include applicable space below the hopper, and upload a drawing for reference.
