Abstract
A compact dust removal system that can be mounted on a substantially rigid receptacle, such as a pail, found at construction sites. The compact dust removal system includes an array of cyclonic separators of different sizes disposed within a mesh filter. The system can be mountable to a pail such that an initial dust removal stage occurs by inertial separation along the interior surface of the pail. The system further includes a cyclone inlet manifold configured to distribute dust-laden air among the cyclonic separators at least partially based on the size of dust particles within the dust-laden air.

A dust removal device comprising:
- a housing configured to couple with and cover an upper rim of a substantially rigid receptacle to form an enclosed interior space within the receptacle;
- an inlet at least partially disposed within the housing, the inlet configured to receive dust-laden air from outside the interior space and direct the dust-laden air into the interior space;

- a mesh screen configured to remove at least a portion of dust particles from dust-laden air traveling from the inlet to the cyclone array;
- a pump configured to drive air through the dust removal system;
- and
- at least one air filter disposed within the housing, the air filter configured to receive air that has passed through at least one cyclonic separator of the cyclone array,
- wherein the dust removal device can be interchangeably coupled to a plurality of substantially rigid receptacles.
