The Hydro SS 700 direct-feed fogging system is our smallest and quietest atomizer, engineered for dependable humidification, evaporative cooling, and spot cooling in commercial, agricultural, and residential environments.
Unlike high-pressure misting systems that rely on nozzles and pumps, the SS 700-DF connects to an ordinary water supply and uses centrifugal atomization to produce tiny particles that evaporate quickly for efficient cooling and humidity control.
The Direct Feed configuration is regulated by a stainless-steel visual flowmeter panel and can be operated continuously or automated using a secondary controller. Its stainless-steel construction and UV-stabilized polymers make it well suited for greenhouse and other harsh-environment applications.

The Hydro SS 700-DF is designed for compact, reliable humidification and cooling where quiet operation, simple installation, and consistent fog production are important. Its direct-feed design makes it an excellent fit for permanent installations using a standard pressurized water supply.
Typical applications include:
The SS 700-DF delivers fine fog production without the complexity of high-pressure nozzles, making it a practical solution for users who need dependable performance in a small-format atomizer.
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.
