A filter cartridge for a sterilizing cabinet includes a first gasket comprising a rigid or flexible edge portion and forming a frame defining a hollow center portion, a first filter comprising a porous material for maintaining a sterilized condition in the sterilizing cabinet and passing gaseous materials through the porous material, wherein the first filter is affixed to the first gasket, and a second filter comprising a porous material for maintaining a sterilized condition in the sterilizing cabinet and passing gaseous materials through the porous material, wherein the second filter is either affixed to the first filter or the first gasket opposite the first filter, and wherein the filter cartridge provides sufficient structural integrity to form a sealing interface with a confronting surface of the sterilizing cabinet.

An object of the present invention is to provide a safety cabinet that allows a clearer observation of contamination of an operation stage surface. In order to realize the object, the safety cabinet is configured to include an operation space including an operation stage; a front panel formed in a front surface of the operation space; an operation opening provided in a lower portion of the front panel; a suction port that is provided in the vicinity of the operation opening on a front side of the operation stage to lead downward; and an air circulation path through which air suctioned from the suction port flows along a lower portion, a back surface, and an upper portion of the operation space, in which the operation stage is made of a transparent material, and a light source is provided to irradiate the operation stage with a light from a side of the operation stage, which is opposite to the operation space.

Systems and apparatuses include a generator set including a chassis, an engine mounted to the chassis, an inverter coupled to the engine, and a housing coupled to the chassis. The engine and inverter are contained within the chassis and the housing. An air cleaner is sized to fit within the housing and includes an air cleaner housing defining an inlet and an outlet, and a sealing surface positioned between the inlet and the outlet, and a cover pivotably coupled to the air cleaner housing and including a carrier sized to be received within the air cleaner housing. The cover includes an air filter receiving feature structured to support an air filter and position the air filter between the inlet and the outlet, and a carrier flange structured to seal a portion of the air filter between the sealing surface and the carrier flange when the cover is arranged in a closed position.

A filter device for filtering particles from an air flow has an inlet channel through which the air to be cleaned flows, at least one filter element through which the air can flow and which is held replaceably in a flow channel, and an outlet channel through which the cleaned air flows. The filter device has an insertion chamber which can be closed by a door and from which a filter element can be fed to the flow channel, and an output chamber which can be closed by a closure element and into which a filter element can be fed from the flow channel. A cover is attachable to the filter element, which covers a filter cake on the filter element so that the unit of filter element and cover is removable from the output chamber together.

A humidifying air purifier includes a door assembly supported and configured to be selectively drawn out of a front side of a cabinet and drawn into the front side of the cabinet to respectively open and close an inner portion of the cabinet. The door assembly includes an accommodation portion configured to support an air filter and a humidifying device which are both drawn out of and into the humidifying air purifier with the door assembly.

A filtration sealing system is provided for sealing a filter element in a housing at a mating interface therebetween. The sealing system includes a keyed interface. A replacement filter element is provided for such filtration sealing system, with the replacement filter element including a keyed interface.

The present invention provides a gas generator and comprises an electrolytic cell, a condensate filter device, and an atomizing device. The electrolytic cell is for electrolyzing electrolyzed water to generate a gas with hydrogen. The condensate filter device includes a gas pathway, a filter, and an isolated component. The isolated component is used for limiting the movement of the filter inside the gas pathway. The gas generated from the electrolytic cell is condensed and filtered through the filter for generating a filtered gas with hydrogen. The atomizing device is used for generating an atomizing gas to be mixed with the filtered gas to generate a healthy gas. The present invention uses the condensate filter device to filter out the electrolyte from the filtered gas with hydrogen to be mixed with the atomizing gas for generating the healthy gas.
