The STR-1-15L22 is a transformer fan speed controller with which you can manually regulate the fan speed of single-phase motors in 5 steps. The unit also has an off-position. It needs a 230 VAC/50-60 Hz supply voltage and has an unregulated output of 230 VAC that can control a damper, an external status indicator, etc. This output is active as soon as the motor is enabled. The sinusoidal shape of the generated motor voltage results in an exceptionally quiet motor operation and extended service life. The special impregnated coating reduces the electrical noise from the built-in autotransformer. This series is available in different amperes. The casing of the controllers up to 7,5 A is made from high quality plastic, while the models above 7,5 A have a metal housing. This transformer doesn't need any configuration. Once installed, it's ready for use.

The first one is the base, which ensures stable attachment of the base on the top of the chimney. It can be in the shape of a cone, plate or other form enabling a safe connection to the fireplace. The main part of the cowl is the outlet section, which is responsible for exhausting exhaust gases outside the building. It can have different shapes such as cylindrical, conical or flat, depending on the requirements and design. This part is important for ensuring proper airflow and minimizing resistance to exhaust gases.
