GT 500 Direct Feed

GT 500 Fog Fan – Direct Feed
Industrial Humidification &
Evaporative Cooling System

Manufactured in the USA by Jaybird Manufacturing

The Aquafog GT-500 centrifugal fogging system is designed for industrial humidification, evaporative cooling, and environmental control in warehouses, manufacturing facilities, agricultural operations, and commercial spaces where OSHA-compliant equipment and reliable fogging performance are required.

Unlike high-pressure misting systems or air-assisted nozzle foggers, the GT-500 uses Jaybird’s centrifugal atomization technology to produce fine fog particles without clogging nozzles or requiring high-pressure pumps. The 14-inch industrial atomizer produces fog that evaporates quickly for effective cooling and humidity control.

The GT-500 was engineered for facilities where the stronger propulsion of the Turbo XE series is not required. By using a milder fan blade pitch and an OSHA-compliant safety guard, the GT-500 provides dependable fogging performance while maintaining safe operation in occupied workspaces.

Aquafog SST Flowmeter Panel

GT 500-DF units come with a visual flowmeter panel of your choice.

The flowmeter panel connects to a pressurized water supply and allows the operator to monitor and adjust the water feed rate going to the GT atomizer. A precision needle valve regulates the flow, while the clear polycarbonate meter provides easy visual confirmation of system operation.

Direct-feed GT units should always include a water solenoid shutoff valve. This ensures water flow stops automatically whenever power to the unit is interrupted or cycled off. All Jaybird control packages already include an integrated solenoid. If operating manually or using a preexisting control system, a separate solenoid must be installed in the supply line.

Because the GT operates over a lower overall flow range than the XE, selecting the correct flowmeter range is especially important. For best reliability, choose the smallest flowmeter that still covers your intended operating range. This keeps the needle valve operating in a more open position and helps reduce restriction from ordinary sediment or biological buildup sometimes present in water supplies.

Lower feed rates generally produce a drier, finer fog. Higher feed rates produce heavier fog, larger droplets, and more drain-off.

Flowmeter Selection Guide

Flowmeter Scale Best Operating Zone (GPH) Net Fogging Output (GPH) Drain Discharge (GPH) Average Particle Size Fog Character
1 to 5 GPH Mid-scale to 5 Up to 3.5 Up to 1.5 8 to 12 Microns Finest / driest fog
2 to 10 GPH Mid-scale to 10 Up to 5.5 Up to 4.5 12 to 20 Microns General-purpose fogging
3 to 15 GPH Mid-scale to 15 Up to 6 Up to 9 15 to 25 Microns Highest GT output

Selection Tip: If in doubt, do not automatically choose the largest flowmeter. Select the smallest meter that comfortably covers your intended feed rate.

Important: At higher feed rates, excess water is discharged through the drain tube and droplet size increases. Lower-range meters are generally preferred for drier fog and finer performance, while higher-range meters are better suited when maximum GT output is needed.

Water Control Note: GT direct-feed units operated manually or connected to preexisting control systems should always include a water solenoid (or equivalent shutoff valve) to automatically stop water flow whenever power to the unit is interrupted or cycled off. See Water Solenoid - DF by selecting the Control Packages tab above.

Hydrophilic Front Guard

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.

  • Meets OSHA Safety Regulations
  • 304 Stainless Steel Construction
  • Hydrophilic Surface Treatment for Water Wicking

How Jaybird Atomizes Water Without Nozzles

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.


See comparisons of Jaybird atomizers in action (1:17 video)

At the blade tip, several processes occur simultaneously:

  • The rotating blade atomizes the water into fine droplets
  • A venturi accelerates airflow around the blade
  • A ring of atomizing pins further breaks droplets into fog
  • Particle size is variable and desired size can be controlled by the feed rate

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.

  • XE 360 Oscillator

    Increase Coverage & Circulation

    Ideal for interior applications and permanent hanging installations, the XE 360 Oscillator increases fog coverage and air circulation through smooth, continuous sweeping motion. The oscillating action helps reduce droplet collisions and fallout while producing more uniform coverage patterns up to 70 feet in diameter. This allows the operator to run higher fog output levels than a stationary unit under equal conditions, resulting in less fallout and improved dryness beneath the fog pattern.

    Recommended for indoor use only. While the oscillator assembly is built with a durable stainless steel enclosure and performs well in harsh interior environments, it should not be used in outdoor windy conditions. Wind gusts can place repeated stress on the oscillating housing and gear system, potentially causing premature wear or damage to the mounting assembly. For outdoor applications, a stationary-mounted unit is strongly recommended.
