A pressure relief fan is an aid to expel smoke gases from a building in the event of a fire, in order to improve visibility and allow safe entry. A pressure relief fan can also be used during incidents involving hazardous substances. Depending on the purpose, wind direction and ventilation openings the fan can be flexibly used. For maximum flexibility Hobrand offers battery-powered pressure relief fans. This way the fire brigade is no longer dependent on a power supply during a deployment. Of course the regular 230 volt models and pressure relief fans with a fuel engine remain available as well.
