Canister filters are employed in a wide variety of applications from auto engines to manufacturing equipment. These filters work by passing a liquid substance through a medium that removes debris and/or impurities.
As the filter collects debris and/or impurities, the ability of the filter to perform its function is diminished. A filter requires replacement when the filter medium becomes saturated.
Replacement of a canister filter typically involves removal of the filter from a filter mounting. A new filter is replaced into the filter mounting and thus restores the ability to remove debris and impurities from the liquid substance.
As many filter mountings are down-facing, the fluid remaining inside the filter has a tendency to spill from of the top of the filter and run down the side of the canister filter during the replacement process. This spilled liquid can make the side the canister filter slippery (thus increasing the effort required to remove the filter). Oil-based, as well as many other fluids, are slippery, potentially hazardous, and possibly extremely hot. If the filter is removed by hand (as is typical), the spilled fluid may come into contact with the skin. Any fluid that reaches the ground may pose a threat to the environment by contaminating the soil or water sources as surface run-off.
Thus, there is a need in the art for a device to capture fluid spilled from a canister filter during replacement. It is therefore an object of the present invention to provide a device that attaches to a canister filter that restricts the fluid from dripping down or off the canister, coming into contact with the person replacing the filter, or from reaching the ground.
A method for managing fluid spilled from a filter during filter removal or installation. The Filter Fluid Capture Device captures fluid which is spilled from a canister filter thereby keeping the fluid from dripping off the filter or coming in to contact with the person replacing the filter.
The Filter Fluid Capture Device is installed onto the canister filter by sliding up from the bottom of the filter. The Filter Fluid Capture Device is designed to fit snugly around the circumference of a filter. With the Filter Fluid Capture Device installed on a filter, the Filter Fluid Capture forms a cup or reservoir between the wall of the filter and the Filter Fluid Capture Device. This reservoir contains any spilled fluid by preventing the spilled fluid from leaking past the bottom of the Filter Fluid Capture Device where it meets the filter. The Filter Fluid Capture Device captures spilled fluid into a reservoir during removal or installation of the canister filter.
After the filter is removed, the contents of the capture reservoir can be poured safely into a proper storage container. After emptying, the Filter Fluid Capture Device might be removed and cleaned for re-use. It is also possible that the Filter Fluid Capture Device might be designed for single use and may be discarded with the spent filter. It would also be possible to integrate the Filter Fluid Capture Device into the filter itself so that the filter would essentially have two walls—an inside wall that contains the filter itself and an outside wall that forms a reservoir between the inside and outside walls.
When mated with a filter, the Filter Fluid Capture Device creates a reservoir area (displayed in
Anyone knowledgeable in the art might conceive a Filter Fluid Capture Device which is manufactured into the filter itself without departing from the spirit of the present invention.
