Devices, systems, and methods for the automated cleaning of filters and filter walls within heating, ventilation, and air-conditioning (HVAC) systems. Disclosed devices can include self-cleaning filter assemblies configured to receive and surround at least one filter, such as an HVAC filter. In some embodiments, the self-cleaning assemblies receive and surround at least one filter and at least one fan. For example, at least one filter or filter wall comprising multiple filters and fan may be combined together into a single cube, where the cube is then received and surrounded by the self-cleaning casing. In some embodiments, the self-cleaning assemblies or cubes receive and surround at least one filter, at least one fan, and at least one heat transfer coil. The cleaning system can have different cleaning cycles, such as a cleaning cycle that cleans the filter(s) and a different cleaning cycle that cleans the heat transfer coil.

A method for removing particles from a bodily fluid in a patient with a filtering device, the filtering device being implantable in the patient's body and the method comprising the steps: pass bodily fluid of the patient through a tube forming a main fluid, filtering the bodily fluid passing through said main fluid passageway with a filter connected to the tube, collecting particles in the bodily fluid to be removed passing through the tube, and cleaning the filter with a filter cleaning device by removing particles collected by the filter out of the fluid passageway.

An air filter device of an industrial machine in which an air filter is arranged in a filtered portion of the industrial machine is provided, the air filter device includes: a first operation unit which transports the long air filter toward the filtered portion; a second operation unit which collects the air filter transported from the first operation unit and used in the filtered portion; and a control unit which controls the drive of the first operation unit and the second operation unit and the control unit includes a first determination unit which determines whether or not the air filter in the first operation unit is about to run out or runs out, and outputs, when the first determination unit determines that the air filter is about to run out or runs out, a signal indicating that the air filter needs to be replaced.

A method for controlling and implanting an implantable drainage device is provided. The device is adapted to move body fluid from one part of the body of a patient to another part of the body. The invention also extends to a filter adapted to filter particles from a drained fluid.

The present invention relates to an implantable cassette for holding filters. The cassette is provided with a revolving compartment having a plurality of segments. Each segment is for holding a filter for filtering blood. Also provided is attachment means for attaching the cassette to a blood flow passageway to thereby allow blood to flow through a first segment of the revolving compartment. An operation device for revolving the revolving compartment, to thereby move the first segment out of the blood flow passageway, is also provided.

A filter system including a filter housing with an inlet part, a clean-gas outlet, and a partition wall defining a product chamber and a clean-gas chamber. The partition wall having openings from which filter elements extend downward into the product chamber. The inlet part is placed in an upper part of the product chamber and configured for supplying a product-containing flow of gas to the product chamber. The gas flow being conveyed through the filter elements and into the clean-gas chamber, where the filter system is provided with an air or gas supply placed in the product chamber and configured for leading drying air or gas into or out of the filter system.

A method of drying filter elements in a filter system by passing drying air or gas through a filter inlet and/or through a drying air or gas supply.
