1. A filtration device comprising:
a first opening and a second opening that is smaller than the first opening; and a vortical filter for receiving a fluid extending away from the first opening towards
the second opening, the vortical filter comprising a helical coil having at least one rib extending continuously from the first opening to the second opening, wherein the at least one rib has a width that comprises 30% to 60% of the radius of the helical coil at the first opening,
the vortical filter being configured to generate vortices in the received fluid entering the vortical filter via the first opening and being configured such that filtered fluid exits the side of the vortical filter through a filter media surrounding at least a portion of the circumference of the vortical filter between the first opening and the second opening, wherein filtered materials substantially exit the vortical filter at the second opening.
