Tunnel explosion-proof ventilation fans deliver large airflow volumes—up to 200,000 CFM—while meeting stringent safety requirements for combustible gas or dust environments in mining and highway tunnels.
The fans employ Ex d flameproof motor housings and anti-spark impeller materials, ensuring internal arcs cannot ignite external atmospheres. Static pressures reach 4 kPa to overcome long duct runs.
Integrated variable frequency drives (VFDs) enable demand-driven ventilation, adjusting speed in response to gas sensors and smoke detectors. Soft-start capabilities reduce mechanical stress during activation.
Maintenance is facilitated by split-casing designs, external lubrication points, and inline vibration monitoring. These fans provide resilient, compliant tunnel ventilation under hazardous conditions.
