Cyclonic air filter with exit baffle
First Claim
1. A cyclonic filter having an inlet and outlet comprising:
- a chamber in communication with the inlet, flow from the inlet being directed in a rotational flow about an axis within the chamber;
a first baffle element positioned in the chamber, the first baffle element having at least one inlet; and
a second baffle element positioned within the first baffle element, the second baffle element having at least one outlet, the at least one outlet of the second baffle element being positioned relative to the at least one inlet of the first baffle element in a direction opposite to the rotational flow, the interior of the second baffle element being in communication with the filter outlet.

Abstract
The described embodiments of the present invention include a cyclonic filter having an inlet and outlet. The cyclonic filter includes a chamber in communication with the inlet, flow from the inlet being directed in a rotational flow about an axis within the chamber. The cyclonic filter also includes a first baffle element positioned in the chamber, the first baffle element having at least one inlet. The cyclonic filter further includes a second baffle element positioned within the first baffle element, the second baffle element having at least one outlet, the at least one outlet of the second baffle element being positioned relative to the at least one inlet of the first baffle element in a direction opposite to the rotational flow, the interior of the second baffle element being in communication with the outlet.
