What kind of maintenance do downdraft tables require?

Downdraft tables require regular maintenance to ensure that they function optimally and provide a safe working environment. A poorly maintained downdraft table will not provide effective air filtration and can become a fire risk as particulate builds up on the grate and in the filters. Always refer to the manufacturer’s maintenance guidelines for specific recommendations and intervals. They will provide detailed instructions tailored to the particular model of the downdraft table. Typical maintenance tasks may include:

• Change filters: Check the filters regularly for loading, wear, or damage. Over time, filters will become saturated with captured contaminants. A compressed air filter pulsing mechanism can extend the life of downdraft table air filters.  
• Surface cleaning: The grated surface of the table should be cleaned regularly to ensure consistent airflow and prevent the buildup of potentially flammable debris. Remove any debris or buildup that might block the perforations.
• Clean spark traps: If the system comes with built-in spark arrestance, the spark control system must be cleaned regularly to prevent the buildup of grime. 
• Empty dust tray/containment: The downdraft table may come with a dust tray that needs to be emptied regularly or a particulate clean-out area that must be swept or vacuumed out.
• Motor/blower maintenance: Fans or blowers might require cleaning, lubrication, or, in some cases, replacement parts.
