Construction details

This product from Trial is characterized by the use of high quality materials which make it reliable and long life even at high temperatures.


The motor winding has Class H insulating materials and in its standard version is protected by a self resetting thermal protector. The plastic insulating material is recognized by UL.

The backward curved blades ensure a stable airflow even if the counterpressure is high and unstable.  The super glossy finish of the blades prevents clogging by soot.

The motor assembly to the housing by means of silicone rubber washers prevents heat transmission to the motor and vibration transmission to the scroll.


The Trial steel sheet scroll is lightweight  and can be customized as far as the fastening brackets and the temperature and/or pressure sensors are concerned.

The surface silicon processing provides protection against chemicals which can be found in the combustion fumes.

A complete set of gaskets made out of biosoluble texture and usable up to 1200 °C is available.
