The Seuthe No. 7 smoke generator is a compact electrical smoke unit designed for installation in HO scale model steam locomotives. When powered, it produces a realistic steam effect by gently vaporising special smoke fluid, enhancing the visual realism of running locomotives.

This universal version is suitable for a wide range of HO/OO locomotives that are pre-fitted or adapted for smoke units. It is commonly used in both analogue and digital layouts where a 16–22V supply is available, depending on installation and manufacturer specifications.

The unit is designed for long service life and consistent smoke output when used with appropriate Seuthe smoke fluid.
