Self-Extinguishing Inline Pre-Filter System for Metal Particulate
The BOFA FireBOX MA is for added safety and protection from fire in applications where an increased risk has been recognized. In the rare event that a burning ember is drawn into the fume extraction unit, there is the possibility that 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 in-line FireBOX is an additional precaution.
The built-in temperature controller can be set so that when a 10°C (18°F) temperature rise over the pre-set ambient temperature is detected, the 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 this does not completely suppress the fire and the temperature rises another 10°C (18°F) then the fire extinguisher will be activated.
Special Note on Shipping from the manufacturer:
Shipping Instructions - Dangerous Goods Classification
The Firebox product category (MA & GA) contains components that mean it has been classified as Dangerous goods under the Dangerous Goods Regulations.
The classification of the product falls under UN1044 - FIRE EXTINGUISHERS, CLASS 2.2 and will need addressing for transport via both Air and Sea. On the occasion that the product is to be moved via road freight then it is exempt from ADR Regulations for transport (Under Special Provision 594) and no further action is required.
Reverse flow air technology
The reverse flow air technology feature causes a fall in velocity and air direction change. Larger particulate falls out of the air stream into the filter drop-out chamber. With less particulate entering the filter media the filter life is significantly increased. Contaminated air entering the drop-out chamber is pulled vertically through the filters.
Patented DeepPleat DUO Filters
The BOFA DeepPleat DUO pre-filter incorporates a massive drop-out chamber within the filter. Above this chamber but still within the housing there is a sealed deep pleat layer of F8 media giving a surface area in excess of 6/12/30 sq meters. Thanks to a specially molded grommet style gasket situated within the drop-out chamber the DeepPleat DUO is designed for easy and safer installation and replacement, which is particularly important as often harmful contaminants are captured within the filter.
