  • Patent number: 11975282
    Abstract: A filter is provided for removing contaminants from a gas flow (e.g., an air flow). Multiple panel filters are arranged in a filter housing. The panel filters are arranged parallel or near-parallel to a main gas flow direction and spaced apart to define elongated gas flow channels between adjacent panel filters, each elongated gas flow channel extending generally in the gas flow direction. The elongated gas flow channels include inlet channel(s) and outlet channel(a) arranged in an alternating manner, the inlet channel(s) configured receiving the gas flow at the inlet end and the outlet channel(s) outputting a filtered gas flow from the outlet end. Gas flow redirecting structures are arranged to redirect the gas flow in each inlet channel through adjacent panel filter(s) and into adjacent outlet channel(s). The filter may provide a pressure drop of less than 3 iwg, less than 1 iwg, or less than 0.3 iwg.

  • Patent number: 11958006
    Abstract: Virus and microbe-killing, self-sterilizing resistive heated air filters and methods of making and using same methods. The air filter is includes laser-induced graphene (LIG), a porous conductive graphene foam formed through photothermal conversion of a polyimide film (or another source or source of polymer or other LIG precursor material) by a laser source. The LIG in the air filter can capture particulates and bacteria. The bacteria cannot proliferate even when submerged in culture medium. Through a periodic Joule-heating mechanism, the filter easily reaches greater than 300° C. This destroys any microorganisms including bacteria, along with molecules that can cause adverse biological reactions and diseases such as viruses, pyrogens, allergens, exotoxins, endotoxins, teichoic acids, mycotoxins, nucleic acids, and prions.

  • Patent number: 11889972
    Abstract: A method is provided for operating a suction device that includes a suction unit and a removable filtering device. The suction unit generates a suction flow that flows through the filtering device when arranged on the suction device, in which, after the suction unit is started up, a check is performed of whether the filtering device is present, and if detected as not present, the suction unit is switched off. An evaluation unit uses check data to determine whether a switch-off signal is to be generated for the suction unit. The evaluation unit uses an algorithm or a table to arrive at a decision on switching off the suction unit based on the check data. The table contains at least one threshold value or the algorithm defines at least one threshold value, wherein the at least one threshold value is a threshold value for switching off the suction unit.
