S300FL - Aluminum direct spiral duct mounted double deflection supply grille with radius end cap

The S300FL is a durable and efficient solution for HVAC supply air distribution, designed for direct installation onto spiral ducts. This model features a double deflection configuration with 3/4" spaced blades running parallel to the grille's long dimension, allowing for precise airflow control. The aluminum construction ensures longevity and corrosion resistance, while the radius end caps provide a seamless and aesthetically pleasing fit with duct sizes ranging from 6" to 36" in even increments.

Key features of the S300FL include its time and cost-saving direct-to-duct mounting system, eliminating the need for complicated transition pieces. Available in both single and double deflection options, the grille offers versatile airflow patterns to suit various applications. Adjustable vertical or horizontal louvers provide further customization of air throw and diffusion, while the included foam gasketing ensures a tight seal against the ductwork, minimizing air leakage. For added control, an optional Air Scoop Damper (ASD) allows for easy volume adjustment accessible from the grille face.

The S300FL aluminum direct spiral duct mounted supply grille is ideally suited for a wide range of commercial and industrial HVAC projects. Its efficient design and compatibility with standard spiral ductwork make it a popular choice for applications such as offices, retail spaces, schools, and other buildings where effective and aesthetically pleasing air distribution is paramount. The S300FL aligns with Masterformat Division 23 37 13, encompassing diffusers, registers, and grilles within construction specifications.
