Disclosed is an air-cleaning blower (“ACB”) that includes an inlet cover, housing, clean-side cover, and impeller. The inlet cover may be a rigid flat surface with a central opening. The housing may have a hollow inner cavity and walls that form an incomplete cylinder with a slit between the walls. The clean-side cover may be a rigid flat surface with apertures, and with brackets extending between the apertures to connect an impeller/motor mount to the clean-side cover. The impeller may be mounted on the impeller/motor mount inside the housing between the inlet cover and the clean-side cover. The impeller rotates to induce suction of particulate-pervaded air or gas through the central opening, to circulate the heavier particulates against an interior of the walls until ejection through the slit, and to circulate the lighter cleaned air or gas in front of the heavier particulates until ejection through the apertures.

The present disclosure describes modular fan unit systems and assemblies. A modular fan unit system assembly may include a mounting structure; and a modular fan unit system. The system may include a plurality of modular fan units, each modular fan unit having an outer housing surrounding an internal fan, the modular fan units being configured to be individually separated from the system; a filter housing unit having a plurality of filter compartments, each filter compartment configured to hold an individual air filter, wherein each modular fan unit is mounted and secured to a back side of the filter housing unit such that each modular fan unit aligns with a respective filter compartment; a plurality of louvre units, each louvre unit removably mounted to a front side of the filter housing unit such that each louvre unit aligns with a respective filter compartment; and a controller communicatively coupled with each of the modular fan units, wherein the modular fan unit system is mounted to the mounting structure.

The present invention relates to an air cleaner, including a body forming an exterior; a suction portion formed on the body to suck air; a discharge portion formed on the body and discharging the air sucked through the suction portion; and a fan module provided in the body to form a flow of air flowing from the suction portion to the discharge portion, wherein the fan module includes: a driving portion forming a rotation shaft and generating power; a fan receiving the power from the driving portion and rotating about the rotation shaft; and a shroud accommodating the fan and provided between the suction portion and the discharge portion to guide the air sucked through the suction portion to the discharge portion, and the shroud includes a guide portion guiding foreign substances introduced through the discharge portion in a direction opposite to the flow of air.

A handheld blower includes a fan for generating an air flow, a motor for driving the fan to rotate about a central axis, a battery pack for supplying power to the motor, an air duct portion including an air duct, the air duct extending long the central axis, a coupling portion for coupling with the battery pack, and a connection portion for connecting the air duct portion with the coupling portion. The fan is received in the air duct. The air duct includes an air duct inlet and an air duct outlet which are respectively located at the two ends of the air duct. The air duct inlet is located between the air duct outlet and the coupling portion. The connection portion is provided with an air intake space located between the air duct inlet and the coupling portion. The air intake space is opened in a radial direction of the central axis.

A device that provides personal comfort to the user while simultaneously providing insect control, both functionalities facilitated by a fan component that creates airflow through the device, such airflow drawing insects into the inlet end of the device for insect control and blowing air out of the outlet end of the device for personal comfort of the user, while a trapping component inside the device prevents the insects from exiting with the outlet air and a killing component inside the device kills the insects for insect control purposes.

A fan can include a motor for driving a set of blades to move a volume of air about a space. A cage can be provided to encase the set of blades to protect the fan, as well as permit a volume of air to move through the cage. A mount bracket couples to the cage, and can include a first portion including a first pair of hooks connecting the first portion to the cage, with the first portion including a pair of apertures and an attachment feature, and a second portion including a second pair of hooks connecting the first portion to the cage, with the second portion including a pair of extensions configured to secure to the first portion at the pair of apertures. The attachment feature is configured to couple an accessory to the cage via the mount bracket.

A rotating plate misting fan (RPMF) is capable of delivering cooling to industrial environments including loading bays for docked trailers. The RPMF includes a rotating plate assembly configured to eliminate or minimize water collection in the environment area.

The invention is about a step-less speed regulating oscillating fan, relates to the technical field of fans, and includes a fan body and a base; the fan body is installed on the base, a motor is fixedly installed on the fan body, and blades are fixedly installed on an output shaft of the motor; a battery is installed inside the base, a PCB main board is installed inside the base, an encoder is installed on the base and is used to control the revolution speed of the fan, a rotary knob is fixedly installed on a rotary part of the encoder, and speed control of the fan can be realized by gently turning the rotary knob and using the encoder to control the output revolution speed of the motor, limitation of gear positions and mechanical rotary knob are avoided, and the purpose of saving efforts can be realized.

A dust-proof telecommunication system is disclosed. The dust-proof telecommunication system includes a chassis, critical components located within the chassis, and a filter module located within the chassis near at least some of the critical components that need to be cooled. For example, the critical components include a central processing unit (CPU), a system on chip (SoC), a memory module, a PCIe card, and/or a chipset. The filter module has a filter cover that surrounds at least in part the critical components, a first air filter located at an inlet of an airflow, and a second air filter located at an outlet. The critical components located at a protective space within the chassis receive and are cooled by the airflow passing through the air filter.

A blower may include a lower case having a suction port and a fan and an upper case having at least one main discharge port and at least one auxiliary discharge port. The auxiliary discharge port may be positioned in front of and below the main discharge port to discharge air introduced through the suction port upward. A door may open and/or close the auxiliary discharge port, and a door motor may power the door. The upper case may be formed as two towers defining a blowing space therebetween, and the at least one auxiliary discharge port may include a plurality of auxiliary discharge ports formed in inner walls of the two towers to face each other.
