The portable hot air generator MASTER B 3.3 IT is a localized heating system for small industrial, commercial, or residential environments. Equipped with a thermally protected motor with zero oxygen consumption and highly silent operation, it differs from other heaters due to the absence of open flames and emissions of gas or diesel into the air. Master B 3.3 IT is therefore suitable for use in enclosed spaces or areas with poor ventilation.

These hot air generators utilize the Joule effect generated by the current passing through the electric heating elements, which heat the air supplied by an axial fan. The built-in temperature sensor constantly monitors the ambient temperature, and overheating is prevented by the over-temperature thermostat. The heat is also adjustable.

Another noteworthy feature of these generators is their low noise level, ease of transport, and the use of stainless steel heating elements.


This Master heater is entirely produced in Italy. Made in Italy is synonymous with precision and high technical quality.
