If a smouldering ember is drawn into the fume extraction unit, there is the likelihood that the filter contents could ignite. Any resultant fire would normally be contained inside the extraction unit, but this could cause noteworthy damage and in extreme conditions the hazard may extend beyond the extraction unit. For a process where such dangers can be identified, extra assurance in an inline FireBOX is recommended
The internal temperature controller can be set so when a 10°C (18°F) temperature rise over the pre-set ambient temperature is sensed, the FireBOX GA will activate the shut-off valves and turn off the power supply to the extraction unit, preventing airflow to the FireBOX and reducing the fire. On the off-chance that the temperature rises by another 10°C (18°F) at that point the internal fire extinguisher will automatically be activated.
An Independent testing body has found the FireBOX GA contains and smothers fires comprising of burning polymer particulate. The FireBOX GA is intended for general applications (GA) but is not for use in metal-based applications.
Please refer to the FireBOX MA for metal-based applications or get in touch with us to help you choose the right system.
