An automatic dust removal device for a vehicle is provided. The device constantly senses dust in the interior of the vehicle and automatically removes the detected dust. The device includes a dust sensor that senses dust concentration in the interior of the vehicle and a controller that operates an air-conditioning device. The controller determines whether dust in the interior of the vehicle requires removal based on a signal from the dust sensor. An air-conditioning device for removing dust from the air is operated to activate a dust removal mode based on a signal from the controller. Thus, an intake door is closed to block inflow of external air into the interior of the vehicle and the air in the interior of the vehicle passes through an air filter and is circulated by a blower.

A filter door for closing a filter housing, in an industrial extraction system, wherein the filter door is fastened, with at least two locking elements relative to the housing surface wherein the filter door is pivotally arranged on one side by a slotted guide on the housing surface and is provided with a movable pivot axis. An industrial extraction system is also provided.

An air filtration assembly for filtering airborne pollutants associated with soldering may include a housing which may include an intake and an exhaust, a filter which may be disposed in the housing between the intake and the exhaust, a blower which may draw an airflow into the air filtration assembly through the intake, the filter and out the exhaust, and a heat resistant pad which may be removably operably coupled to an exterior of the housing. A top surface of the heat resistant pad may be disposed substantially parallel to a work surface on which the air filtration assembly may be disposed.

Described herein are examples of protective insulative enclosures which include a housing, comprising a sleeve, and a strap. The sleeve may be configured to envelop a filter, enclosing the filter. The sleeve comprises an insulated material. The strap may be coupled to the sleeve and is configured to prevent inadvertent dislodgment of the sleeve from the filter. The strap may be further configured to securely fasten the protective insulative enclosure to a vehicle body by attaching it to a specific part of the vehicle body.

A versatile and customizable air purification and security system is provided and designed for integration with various openings such as windows and doors. The system is provided with a robust frame that can be constructed from materials including steel, aluminum, composite materials, wood, PVC, or carbon fiber, ensuring adaptability to different environments and durability requirements. The frame is securely attached using a variety of brackets and retainers. A hinged door, made from materials such as steel, aluminum, wood, glass, acrylic, or polycarbonate, incorporates custom artwork and cutouts for aesthetic and functional purposes, including airflow and natural light passage.
