Abstract
A device for filtering fluids which is cleanable and re-usable is described. The device includes a cylindrical canister, a cylindrical lid and a filter cartridge. The device is adapted to be disposed in a fluid flow circuit, filtering particulate from the fluid circulating therein. The filter cartridge is quickly removed, cleaned and reused. The fluid enters and exits the device from the top end through fluid inlets and an outlet extending through the lid perpendicular to the lids upper planar surface, thereby reducing the amount of space required to mount the device. The fluid inlets include sloping fins that direct fluids in the filtering chamber in a spiraling action, thereby increasing the effectiveness of the filter.
