GT 500-HS Fog Fan – Hanging Sump
Industrial Humidification &
Cooling System

Manufactured in the USA by Jaybird Manufacturing

The Aquafog GT-500-HS centrifugal fogging system is designed for industrial humidification, evaporative cooling, and environmental control in facilities where a floor drain or continuous water supply may not be available.

The hanging sump configuration recirculates unused water, allowing installation in locations where plumbing or drainage connections are limited.

Unlike high-pressure misting systems or air-assisted nozzle foggers, the GT-500-HS 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 rapidly for effective cooling and humidity control.

Because the GT platform operates with milder air propulsion and quieter airflow, it allows the use of OSHA-compliant safety guards, making it suitable for occupied industrial and agricultural environments.

The GT-500-HS Hanging Sump system includes a recirculating reservoir that captures and reuses excess water.

Water flow is regulated using a quarter-turn ball valve, and the system can be operated continuously or automated using a secondary humidity or temperature controller.

Drain-Free Humidification & Cooling Applications

The Jaybird Aquafog GT-500-HS Hanging Sump system is designed for humidification and evaporative cooling applications where a floor drain or continuous water supply may not be available.

The integrated recirculating sump tank captures and reuses water, allowing reliable fog production in environments that require a self-contained humidification system.

Designed to be suspended
– not for tabletop use

Typical applications include:

  • Greenhouse humidification systems
  • Agricultural and horticulture facilities
  • Mushroom growing operations
  • Industrial spaces without floor drainage
  • Controlled-environment agriculture
  • Warehouses and manufacturing environments

Unlike high-pressure misting systems that rely on small nozzles prone to clogging, the GT 500-HS utilizes centrifugal fogging technology to produce consistent droplet size and dependable long-term operation in demanding environments.

Features & Controls

GT 500-HS units include an internal feed pump, a manual 1/4-turn flow control valve, an illuminated On/Off power switch, and an internal float valve to maintain proper tank water level during operation.

  • Large tank access lid
  • 1/4-turn flow control valve
  • 3 gallon recirculation tank
  • Indoor/Outdoor rated (IP55)
  • Illuminated push-button switch
  • Garden hose connection

The manual ball valve allows operators to adjust fogging output based on the application. Lower feed rates generally produce a drier, finer fog, while higher feed rates increase output volume for broader coverage.

Flow Control Guide

Valve Position Typical Use Fog Character
Full Open Evaporative cooling, greenhouse cooling, concrete curing, mushroom growing Highest output / heavier fog
Mid Open General humidification, horticulture, wine barrel storage, wood/lumber/paper applications Balanced output / general-purpose fogging
Slightly Open Textile humidification, dust suppression, static control, lighter treatment applications Drier / finer fog

Control Tip: Start with a lower valve setting and increase flow only as needed. This helps maintain finer fog quality and reduces excess wetting.

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.
