BOFA’s AD 4000 laser fume extraction unit combines large filter capacity with high airflows. This combination makes the AD 4000 ideal for large laser engravers, laser cutters as well as multiple laser coding installations.
Easily accessible filters are accommodated by the uniquely styled gas spring assisted ‘Gull Winged’ doors, which allow for maximum space and ease when changing filters. Unit interfaces such as stop/start and system failure are available as options.
Key features of the AD 4000
BOFA uses mini pleat design HEPA (high efficiency particulate air) filters which are tested and certified to a minimum efficiency of 99.997% down to 0.3 microns and 95% as small as 0.1 micron. They incorporate a series of webbing between the pleated media. This feature not only guarantees even spacing for full filter coverage between each pleat, but also alleviates the possibility of airflow vibration or collapse.
Automatic flow control (AFC) technology
Automatic flow control (AFC) allows the operator to preset the correct airflow rates for the specific application, subsequently maintaining the airflow. This generates lower noise levels and ensures further protection of the more expensive HEPA filters.
Advanced carbon filter (ACF) technology
ACF assures safe capture and removal of hazardous fumes.
Contaminated air must remain in contact with the carbon bed for a period of time sufficient to ensure that no contaminants or odours are emitted (‘dwell time’). Our filters have been developed to capture all contaminants and odours, eliminating the risk of bypass and/or tunnelling.
