A system includes an unmanned aerial vehicle including a chassis, a tank attached to the chassis, a sprayer fluidly connected to the tank, a heating element attached to the chassis, a fan drawing air over the heating element, and a clamp attached to the chassis; and a computer in communication with the unmanned aerial vehicle and programmed to instruct the clamp to attach to an external sensor of a vehicle, instruct the sprayer to spray water and detergent onto the external sensor, and instruct the fan to blow heated air at the external sensor.

A fan assembly, and associated methods are shown that may include tapering configurations in a nozzle assembly. Configurations are shown that are optimized for thrust. Examples of assemblies and methods are shown that include sound attenuating materials and jagged edges to reduce noise. Configurations are shown that provide a substantially constant or increasing air velocity. Configurations are also shown that provide a static pressure of 120 percent or less of a given dynamic pressure.

The present disclosure relates to an improved drying apparatus, system and method for use in an automated vehicle cleaning system. Specifically, an improved drying apparatus, system and method is provided, which includes a series of components resulting in combined sound reducing features and incorporating sound absorbing acoustic materials creating a quiet technology system. The present disclosure provides a drying apparatus with an overall lower decibel level, without sacrificing air flow and efficiency in the drying of a vehicle.

In order to provide a treatment installation for treating workpieces that is of simple construction and enables optimised workpiece treatment, it is proposed that the treatment installation should include a treatment chamber and a conveying device, by means of which the workpieces are suppliable to the treatment chamber, are removable from the treatment chamber, and/or are conveyable through the treatment chamber in a conveying direction.

The invention relates to a handheld blower device for the manual pneumatic drying of surfaces by a user of the handheld blower device, comprising a flat nozzle device for ejecting compressed air from the handheld blower device onto the surface to be dried, a handle region, in particular a handle, for manually gripping and guiding the flat nozzle device over the surface to be dried, and a conveying device for conveying the compressed air to the flat nozzle device, wherein the flat nozzle device comprises a flat nozzle, and the conveying device is configured with a stationarily arranged, in particular fixedly arranged, high-pressure blower.

Car wash dryer apparatuses, namely car wash dryer inlet have a reverse flow in that the apparatuses allows a car wash dryer to pull air from the same side of the dryer apparatus to which it expels air. Such a configuration reduces sound levels of the car wash dryer without adding significant static drag. Moreover, such a configuration reduces moisture intake in wet environments, which protects internal components of the dryer apparatus.

A temperature control apparatus for controlling the temperature, in particular for the drying, of objects, in particular vehicle bodies, having a housing, in which a cooling zone having a cooling chamber that defines a longitudinal direction is accommodated. The cooling chamber is assigned at least one cooling-air temperature control device, by means of which temperature-controlled cooling air can be produced, which can be fed to the cooling chamber. In the longitudinal direction, the cooling zone comprises a supply chamber on one longitudinal side of the cooling chamber, in which supply chamber the cooling-air temperature control device is arranged.

A brush for drying and/or washing a vehicle may include a rotating shaft rotatable around a rotation axis thereof and drying/cleaning means for drying/cleaning the vehicle. The brush may also include a first rotatable support plate for supporting the drying/cleaning means. The first plate may be traversed by the shaft and constrained on the shaft in an operating configuration. In some embodiments, a fictional lying plane of the first plate and the rotation axis form an angle other than 90 degrees. The brush may also include a connector to connect the drying/cleaning means to the first plate and positioning means for positioning the first plate in the operating configuration.

An attachment assembly to convert an existing leaf blower into a device for drying vehicles. The attachment assembly includes several interchangeable modular sections, including an adapter section configured to attach to the air outlet of an existing commercial leaf blower. Other sections include air outlet nozzle sections, an extender section, and a weighted section. The inlet side of the nozzle sections, extender section, and weighted section as well as the outlet sides of the adapter section, extender section, and weighted section are uniform so that any of the outlets may be mated with any of the inlets. This allows any configuration of sections desired to be achieved. The adapter section may have a filter placed in the air stream to prevent debris from being blown into the vehicle and damaging the exterior of the vehicle.

A rotary brush for automatic vehicle washing systems, said brush comprising a central unit (2) and a plurality of cleaning elements (3), operatively supported by and coupled to said central unit (2) through removable coupling means (7); the cleaning elements (3) being removable from said central unit (2) and it being possible to replace and/or remove them without requiring the removal of said central unit from the rotary structure; said central unit (2) comprises a rigid shaft (4) that supports a plurality of supporting elements (5) comprising a plurality of lugs (53) to which the cleaning elements (3) are fastened; the rotary brush is characterized in that said cleaning elements (3) comprise bands (33), fringed and fringeless, helically arranged on said central unit (2) in such a way that each band (33) is coupled to a plurality of supporting elements (5).
