It was first marketed by the Dow Chemical Company in 1937. Asbestos Abatement Equipment Unmatched Selection Dust Collectors

Since mercury has a specific gravity of 13. While usually not producing as much suction for use with attachments, this design often will produce more flow when working with large openings and short flow distances.
The specification typically used to indicate the amount of flow which will pass through a clean vacuumed and cleaned power unit when running by itself. One ampere of current will flow through a conductor having one ohm of resistance when a potential of one volt is applied to it. This enhances flow and extends the filter media's effective life span. Dual edge brushing (both sides) can be obtained by running the belt either in the center of the roll or a few inches from one end instead of at the very end of the roll.
The motor brushes are held against the commutator in order to carry the electrical current to the armature windings which are connected to it. The phrase "as small as" means that if all particles were that small, it would still have that efficiency. See also Flow. Therefore, this design in an upright usually performs well when cleaned carpets.

This prevents residual dirt or moisture in the main flow from coming in contact with the armature, field, carbon brushes, etc. This should not be confused with the phrase "down to" which may mean a mixture of particle sizes for the stated efficiency.
