An embodiment of the present invention includes an advanced adjustable density misting delivery system (AMDS) for detecting and neutralizing a fire. The AMDS includes a bladder containing a fire suppressant material, a pump operatively connected to the bladder via a tube, and a nozzle operatively connected to the pump and the bladder via the tube. The AMDS also includes a controller electrically connected to the pump and a sensor in communication with the controller, where the sensor is configured to detect a parameter that indicates the presence of the fire. The controller is configured to transition the pump from a deactivated state to an activated state when the sensor detects the parameter, such that in the deactivated state the pump does not operate, and in the activated state the pump causes the fire suppressant to flow from the bladder, through the tube, and out the nozzle.

A cleaning device for atomizing and spraying liquid in two-phase flow comprising a nozzle provided with multiple liquid bypass pipelines each having liquid guiding outlets inclined at a predetermined angle and an exhaust mesh plate having vertical gas guiding outlets, which makes the high speed liquid flow and high speed gas flow sprayed out therefrom collide against each other sufficiently to form ultra-micro atomized particles with uniform and adjustable size. The ultra-micro atomized particles are sprayed out downwardly to the wafer surface under the acceleration and vertical orientation effects of an atomized particle guiding outlet to perform a reciprocating cleaning for the wafer. Other components such as an ultrasonic or megasonic generation unit, a gas shielding unit, a self-cleaning unit or a rotating unit can also be provided to perform the multifunction of the nozzle.

A chemical discharging fan system has a ducted fan adapted and configured to generate a flow of air from an inlet of the fan into a duct of the fan and through the outlet of the fan. A spray gun is arranged on the fan in the flow of the air generated by the fan. The spray gun has a fluid inlet adapted and configured to receive a pressurized fluid from a fluid supply source. The spray gun is configured to intermittently discharge the fluid from the fluid source into the flow of air generated by the fan. A control is in communication with the spray gun. The control is configured to generate a pulse width modulated signal to cycle the spray gun, which causes the fluid to vaporize upon being discharged from the spray gun into the flow of air generated by the fan.
