Product catalog summary

Overview of Long-throw Jet Nozzle DF-49-ROT
The DF-49-ROT is a long-throw jet nozzle designed for both industrial and aesthetic applications. It features a rotational element that allows for shorter air jet throws, making it suitable for environments requiring both functionality and design appeal. The nozzle is constructed from aluminum with a standard RAL 9010 white finish, and it can be custom painted to match specific decorative needs.

Specifications
The DF-49-ROT is available in five sizes, each with manual swiveling capabilities. The nozzle can swivel up to ±30° in both horizontal and vertical directions, with adjustments in 5° increments. For motor-driven operation, one motor per nozzle is required.

Applications
This nozzle is ideal for large spaces such as hotels, shopping malls, and convention centers, providing medium throws with low noise levels. It is particularly effective for spot cooling in decorative settings.

Performance Data
The selection table provides detailed performance metrics, including air flow (Q), effective velocity (Vk), effective area (Ak), total pressure drop (∆Pt), and sound power (LwA). The throw distances for terminal air velocities of 0.3, 0.5, and 1.0 m/s are also specified.

Long-throw jet nozzle DF-49-ROT MODEL Description The new DF-49-ROT combines long-throw efficiency with a more harmonious design, the novelty in this model relative to the nozzle DF49 is the inclusion of a rotational element that reduces air jet for applications where you need shorter throw. The stylised lines of the nozzles and the possibility of matching current decorative styles make these diffusers a reliable, great-looking component for facilities with more stringent requirements in terms of design and comfort. In addition to effective air blowing at a long distance through nozzles (originally...
