There are two separate air systems in these devices, the air assist and the fume extraction. What would happen if the air assist were replaced with a vacuum nozzle? It could use the same air pump as the fume extractor.
It seems like a vacuum would do an even better job of keeping the work piece and lens clean, as it would remove the particulates instead of just swirling them around.
What totally obvious gotcha am I missing?
