What Venting Does

In a dust or gas deflagration, pressure rises fast. A vent opens at a set burst pressure and releases that energy where it’s safe—so the vessel doesn’t rupture and the event doesn’t cascade through your process.

Venting is often the most cost-effective protection for filters, cyclones, silos, and process vessels. Where external discharge isn’t possible, flameless vents provide indoor relief without a flame jet.

Standards We Align To

  • NFPA 68 — Explosion Protection by Deflagration Venting.
  • NFPA 652 — Fundamentals of Combustible Dust (DHA and management systems).
  • EN 14491 — Dust explosion venting of equipment.
  • ATEX/CE — Certified components for use in explosive atmospheres.

ATEX Canada: Distribute & Install

ATEX Canada supplies and installs the full line of ATEX venting products nationwide. We survey your equipment, size and specify the venting area, deliver hardware, and complete installation and commissioning with documentation for compliance.

Products

  • Rupture panels (flat, domed, high-cycle) with calibrated burst pressure.
  • Flameless vents for indoor applications and restricted discharge zones.
  • Explosion relief doors and housings for large enclosures.
  • Accessories: burst indicators, sensors, weather covers, and ducting.

Applications

  • Dust collectors and baghouses
  • Cyclones and filters
  • Silos, bins, and hoppers
  • Process vessels and enclosures

How We Size & Specify

  • 1. Assessment: Material Kst/Pmax, enclosure strength, volume, and location.
  • 2. Calculations: Required vent area, set pressure, duct losses, and flame path.
  • 3. Selection: Vent type (standard or flameless), accessories, and mounting.
  • 4. Integration: Discharge zoning, guarding, and coordination with isolation/suppression if needed.

Notes on Use

  • Provide a clear discharge area or use flameless vents indoors.
  • Avoid obstructions and minimize vent duct length to reduce losses.
  • Coordinate with isolation to prevent flame/pressure back-feed.
  • Document inspection intervals and keep spares for rapid reset.
