Mobile Fogging Machine

The HRSM is a powerful, compact atomizer for the dispersion of water or liquid chemical solutions. Common applications include large-scale interior humidification, outdoor evaporative cooling and fumigation. Tank holds up to 18 gallons for convenient portable use and attaches to an ordinary water supply for long-term operation.

The HRSM is a centrifugal atomizer that produces billions of tiny, fog-like particles combined with powerful airflow. Humidify interior air spaces with fresh water or add disinfectant to fumigate areas for sterilization of surface areas.

This durable, mobile fogger has powerful propulsion and a pivotable fogging head. It’s flow-rate cannot be calibrated like C/ORSMs, but HRSM has higher fogging capability and is adjustable up to 32 gallons per hour.

  • Nozzle-Free Atomization
  • Adjustable Output up to 32 GPH
  • Chemical & Corrosion Resistant
  • Indoor or Outdoor Use
  • Arrives Fully Assembled

  • CoolAireâ„¢ Fluid Level Auto Shutoff

    If the tank's fluid level gets low, the unit will shut down.

    This custom feature is not compatible with automated controls. If you are planning to automate your unit using a humidistat, timer or other controller, then this option will not work.

    An important add-on feature for certain applications, a momentary push button switch operates the power supply through an electrical relay that is controlled by an internal fluid-level switch. If the unit shuts down, refill the tank and manually push the start button again.
