The FA-430 offers two duct kit options. Both duct kits include a duct, net, adapter and nozzle. The operator has a choice between a rectangular or round nozzle which allows for maximum filtration of the contaminated air in the work area. Contaminated air is captured from the workplace surrounding the soldering station by the hood and then transferred to the FA-430 unit by rigid ducts. A special replacement filter notification function notifies the operator when the filter needs to be replaced.
