Fire prevention is better than cure

Conventional fire protection responds after a fire has started. FirePASS® is designed to prevent ignition from occurring in the first place.

By continuously maintaining the protected environment at a precisely controlled oxygen setpoint, FirePASS® creates a permanent fire-preventive atmosphere—providing uninterrupted protection where preservation, business continuity and safety cannot be compromised.
