Flameless Explosion Vents (EV-VQ & Vigiflam Vi)

Standard explosion vents need a safe discharge zone outside — but what about equipment indoors? Flameless vents combine a rupture panel with a flame-arresting mesh that quenches the fireball as it vents, so pressure escapes but flame doesn’t. That makes NFPA 68 venting possible for dust collectors, conveyors, and vessels located inside the building.

Versions

• EV-VQ: Rectangular flameless vent certified for indoor and outdoor applications
• Vigiflam Vi: Compact flameless vent designed for bucket elevators and belt, chain, and screw conveyors

Key Features:

• Vent indoors safely: Flame-quenching mesh stops the fireball at the vent.
• Certified indoor/outdoor: EV-VQ carries certifications for both installations.
• Conveyor-specific option: Vigiflam Vi protects bucket elevators and enclosed conveyors.
• No ducting to outside: Eliminates long vent ducts that kill venting efficiency.
• NFPA compliant, FM/UL approved: Documentation your insurer will ask for.
