How to choose a dust collector.

Catch the dust at the source.

Dust that is caught where it is released does not spread to the room.

That is point-of-source extraction. An extraction arm, a hood or a hose sits at the source, and the dust collector takes the dust away.

Dust in the air, or dust on surfaces?

The answer decides the machine.

Dust in the air needs a large airflow at the capture point. Dust on surfaces needs a high vacuum. A vacuum cleaner built for surfaces does not remove dust that hangs in the air.

How much air, and through which inlet?

The air must move fast enough in front of the opening to pull the dust in.

How fast depends on how the dust is released. Distance matters most.

Which filter class?

Fine or hazardous dust needs a finer filter.

Depureco fits M class filters as standard, for everyday protection. H class filters catch even finer particles, for the toughest jobs. Special filters exist for hot, sticky or odorous dust.

Which filters a model has, or can have, differs between models. Each product page states the filter.

How is the filter cleaned?

As the filter fills, suction drops. Cleaning releases the dust into the container.

The cleaning system decides how much work it takes and whether you need compressed air. On some models the filter can only be cleaned with the machine switched off.
