A system is provided for treating a space at least partially enclosed by a wall with an aerosolized compound. The system includes a discharge unit, a liquid diffusion appliance, and a conduit extending therebetween. The discharge unit is mounted to a first side of the wall and includes an aerosol outlet in fluid communication with the space to be treated. The liquid diffusion appliance is mounted to a second side of the wall and includes a control system for operating the liquid diffusion appliance to generate and discharge an aerosolized compound from an appliance outlet. The conduit couples the appliance outlet with the discharge unit and defines a passageway through the wall through which the aerosolized compound travels to be discharged into the space to be treated.

A device for generating and dispersing chlorine dioxide which includes a housing, at least one removeable tray having a plurality of compartments contained within an interior of the housing, and a fan in communication with the interior of the housing and the exterior of the housing for directing a current of chlorine dioxide gas that is generated from chemicals that are positioned within the removeable tray(s).

Disclosed is a system that may include a holding tank configured to hold a liquid, a pump configured to receive the liquid from the holding tank, a nozzle configured to emit a fog, and a fan configured to push the fog through a tube. Disclosed also is a method of creating a fog by transferring a liquid from a holding tank to a pump, pumping the liquid to a pressure regulator, moving the liquid from the pressure regulator back to the holding tank when a pressure is above a first value and moving the liquid to a fogger when the pressure is below the first pressure.

A fan (1) for an automatic dispensing device, wherein the fan (1) is configured to generate an air flow when a rotor (3) of the fan (1) is rotating. The fan (1) comprises a drive circuit (6), an electromagnet (8) having at least one electromagnetic coil, the electromagnetic coil connected to the drive circuit (6), a rotor (3) for generating the airflow, and at least four magnets (14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h) arranged on a circle (18) on the rotor (3) and spaced apart by the same angle (alpha), wherein the electromagnet (8) is arranged above or under the circle (18) of the rotor (3) and configured to attract or repel said magnets (14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h), and the drive circuit (6) is configured to switch a current direction in the electromagnetic coil of the electromagnet (8) to sequentially attract and then repel each magnet as the rotor rotates. The fan further comprises a magnetic element (16) arranged above or under the rotor (3) in proximity (20) of the circle (18) of the rotor (3) such that the magnetic element (16) attracts one of the magnets (14a) to its position when the electromagnetic coil is not powered by the drive circuit (6) and the rotor (3) is not rotating or gradually coming to a halt after the electromagnetic coil has been un-powered, wherein none of the other magnets (14b, 14c, 14d, 14e, 14f, 14g, 14h) assumes a position directly under or above the electromagnet (8) when the rotor (3) comes to a halt. In a preferred embodiment, the fan (1) further includes a floating suspension to reduce wear and tear over time.

Devices and methods for the control of pests using the vapors of a pesticidal composition. Compostions, devices and methods for the selective control of pests while not harming one or more beneficial insects are also disclosed. In some embodiments, the pests are bed bugs, fleas, lice, ticks, or the like. In some embodiments, the pests are varroa mites and the beneficial insects are honey bees.

A diffusing apparatus for diffusing a substance in the vapor state into the surrounding air, in particular to a removable assembly of the apparatus that includes a storage container including an orifice and containing a liquid substance selected from semiochemical molecules, pheromones, allomones, kairomones, synomones and fragrances of natural or synthetic origin, and an inner cellular retaining member housed at least in a mouth area of the storage container that is adjacent to the opening and set back from the opening is disclosed. The removable assembly of the apparatus may include a dispensing member including a porous body having an evaporation surface located outside the storage container. The substance may have a viscosity that varies according to temperature.
