GFR line blowers are the ideal solution for spaces with little or no ventilation, ensuring the removal of odors and impurities while providing thermal comfort for occupants. These units accelerate indoor air renewal by filtering polluted outdoor air before introducing it into the environment.
The GFR without filters can be used both as exhaust fans and as supply air units, offering even greater versatility for a wide range of applications.
