A hub is disposed circumferentially around the shaft and coupled to the shaft such that the hub is rotationally locked with respect to the shaft. A filter media is disposed around the hub and secured thereto such that the filter media is rotationally locked with respect to the hub. The filter media is structured for axial flow of a gas through the filter media. A first end cap is disposed on a filter media first end, and a second end cap is disposed on a filter media second end of the filter media. The second end cap is coupled to the first end cap such that the filter media and the hub is secured therebetween.
