SELF-EXTINGUISHING INLINE PRE-FILTER
In the event that a burning ember is drawn into the fume extraction unit, there is the possibility that hot debris in the filters could ignite. Although any resultant fire would typically be retained within the fume extraction unit, this would cause significant damage and in extreme circumstances, the risk may extend beyond the extraction unit. For processes where such risks have been identified, additional protection in the form of an inline FireBOX is an additional precaution.
The built-in temperature controller can be set so when a 10°C (18°F) temperature rise over the pre-set ambient temperature is detected, the FireBOX GA and FireBOX MA will activate the isolating valves and switch off the power to the extraction unit, suppressing the airflow to the FireBOX and reducing the fire. If the temperature rises another 10°C (18°F) then the fire extinguisher will be activated.
Independent tests found the FireBOX GA contains and suppresses fires consisting of burning polymer particulate, and the FireBOX MA is effective at containing and suppressing aluminium metal fires.

Key features of the FireBOX GA and FireBOX MA
- Patented DeepPleat DUO pre-filter – BOFA’s patented pre-filter gives the maximum amount of filtration for the most demanding of laser applications. Combined with BOFA’s large combined filters as standard, making this a globally versatile system.
- Reverse flow air technology (RFA) – Causes a fall in velocity and air direction change. Large particulate falls out of the airstream into the filter’s drop out chamber. With less particulate entering the filter media, the filter life is significantly increased.
- Multi-voltage sensing unit (MVS) – Automatically sense the local voltage and adjusts accordingly, between 90-275V.
