The CoolAire Spirit mobile fogging system is designed specifically for safe, effective cooling and humidification in active industrial environments. Built with Jaybird’s GT centrifugal atomizer, a 65-gallon self-contained tank, and an OSHA-compliant guarded design, the Spirit delivers reliable fog output while prioritizing operator safety and workplace compatibility.
Unlike high-pressure nozzle systems or spinning disc foggers, the Spirit uses nozzle-free centrifugal atomizing technology. This produces extremely fine droplets without clogging, eliminates the need for high-pressure pumps, and significantly reduces maintenance requirements.
Engineered for use in manufacturing facilities, warehouses, and other occupied spaces, the Spirit features an OSHA-compliant front guard and a controlled airflow profile that makes it well-suited for environments where personnel are present.
The unit includes a large integrated tank and a pivoting fogging head for directional control, allowing operators to target specific areas as conditions change. Its rugged wheeled chassis enables fast repositioning for flexible, mobile use.
Fog output is controlled via a quarter-turn ball valve, giving operators simple, precise control over output levels. The system can operate continuously or be integrated with external controls for automated operation.
Applications include industrial humidification, evaporative cooling, odor control, dust suppression, and chemical fogging in both indoor and outdoor environments.
Constructed from stainless steel and UV-stabilized polymers, the Spirit is built for long-term durability in demanding industrial and greenhouse conditions. Its OSHA-guarded configuration makes it an ideal solution for facilities where safety, reliability, and consistent performance are critical.

The CoolAire Spirit mobile fogging system is designed for industrial evaporative cooling, humidification, and environmental control in facilities where OSHA-guarded equipment, quieter airflow, and dependable fogging performance are required.
Typical applications include:
By combining Jaybird’s GT centrifugal atomizer with an OSHA-guarded mobile platform and large integrated water tank, the Spirit provides reliable portable fogging performance for facilities where operator safety and controlled airflow are priorities.
The CoolAire Spirit mobile fogging system provides portable evaporative cooling, humidification, and chemical fogging for manufacturing facilities, warehouses, industrial workspaces, and other environments where OSHA-compliant guarding and quieter airflow are preferred.
Unlike high-pressure misting systems, Jaybird centrifugal fogging units operate without clogging nozzles or high-pressure pumps, producing extremely fine fog droplets that evaporate quickly and efficiently for cooling and humidity control.
Common industrial applications include:
Because the Spirit is built on a mobile platform with an OSHA-guarded design and integrated water tank, it can be quickly deployed where temporary cooling or humidification is needed without requiring a permanent installation. Its lower-velocity airflow makes it especially well suited for occupied industrial spaces and facilities where quieter operation is preferred.
The Spirit uses a single-valve flow control system with an integrated restrictor, providing both minimum and maximum output from one control point. Even when the valve is fully closed, a preset minimum flow is maintained through the internal restrictor, allowing the unit to continue fogging while ensuring proper operation at all fogging angles, including upward positioning.
Opening the valve increases output up to approximately 13 GPH, allowing operators to adjust fogging volume to match application requirements..


The Spirit includes a built-in mechanical oscillator that distributes fog across a wide area, improving coverage without requiring constant repositioning.
By adjusting the sweep angle, operators can focus fog where it’s needed most, increasing efficiency and reducing wasted output.
Key Features:

The front guard meets OSHA safety regulations and is specially processed to create hydrophilic properties, allowing water to wick down the guard and back into the housing rather than bead and be thrown outward by the spinning atomizer.

The (SST) version includes all stainless-steel plumbing components installed in place of standard brass fittings. This option is recommended when fogging highly corrosive chemicals or sanitation solutions.
Jaybird fog systems use a patented centrifugal atomizing blade developed in 1986. Water enters a reservoir behind the fan blade and is forced through internal channels inside each blade. As the blade spins, centrifugal force drives water toward the blade tips where it exits through precision openings.

At the blade tip, several processes occur simultaneously:
This multi-stage atomization process allows Jaybird systems to produce large volumes of fog while using a simple, reliable design with no high-pressure pumps or clogging nozzles.
The result is powerful fog production, strong air propulsion, and long-term reliability.
