112 Why wider filtering area is not making automatically a better machine? In the industrial sector, productivity, resistance and breakeven expectations are growing. The ideal vacuum would be then a machine filtering any kind of dust (also the thinnest) being able to work continuously without the need to clean the filter and without any maintenance. It is more important to get close effectively to this target rather than the way we can reach this. This is the reason why is useless having a big filtering area if the filter is still clogging up fast and more often I need to stop working to clean it. In our machines we developed the best prevention of the problem (avoiding dust is reaching quickly the filter) rather than trying a solution afterwards (since the filter is clogging up quickly, extending the filtering area it is supposed to extend the effectiveness). It doesn’t matter how wide is the filter, but for how long can work the machine without the need to clean the filter… And with this issue, we are the best. When either more airflow or more depressure is necessary? The airflow helps the dirt transport trough long pipes. Longer is the hose, better is bigger airflow; still with light dust it is better having lower depressure: the inlet air speed will be lower, the harder the dirt is getting in touch with the filter. When residuals have high specific weight, depressure is more important than airflow to win gravity force of dirt attached to the surface. Industrial Wet & dry vacuum cleaners
