There is a decisive relationship between air speed, air volume and pressure at the scene of the fire. This determines the safety of the first responder and the speed with which the fire scene can be cleared and subsequently extinguished.
BlowHard firefighting ventilators have been tested and comply with the new DIN 14963 standard for portable ventilation equipment.

Battery life is important because the decision should be yours when to stop using it. Blowhard relies on integrated batteries as they promise lossless power transfer, longer runtime and longer life than is possible with replaceable batteries. The integrated technology allows, in addition to a temperature management of the batteries, the IP 67 standard (dustproof & waterproof) and is therefore also ideally suited for tough applications.
Power without control is useless. Even the highest technical values are of no use if it does not arrive and can not be used at the place of operation. The BLOWHARD High-Flow-Jet airflow management system smartly turns the already high performance values of BLOWHARD fans into an unbeatable helper in fire management.
The blowhard fan design allows you to continuously tilt the airflow up to 180 degrees. This freedom allows for a wide range of tactical settings and arrangements at the scene, giving you effective and safe PPV ventilation.
Blowhard devices are designed to be quickly and effectively put into action. In this regard, the weight and volume of the PPV fans play a key role for rescuers. The devices are light enough to be brought to the scene even by a single person.
Blowhard products are built for use in the harshest conditions on site. Despite the lightness of the devices, no compromises are made on the solid construction. The devices are suitable for many years of use in the harshest conditions.
The basis of a good fan is good performance values. Not only the battery, the motor and the electronics used are decisive, but also the flow design of the fan unit, such as the rotor blades and their number, as well as the design of the air grille and much more.
Every second counts at the scene of a fire. Both for the fire scene and for rescuers, as well as for the possible victims. Equipment that supports this rescue must therefore be ready for use quickly. The concentration should be on the operation and the tactics of the operation and not in setting up the equipment. Blowhard ventilators are built in such a way that anyone can set them up quickly at the scene of an emergency, even without explanation. No matter whether professional fire department or volunteer fire department.
Stand in place, start the positive pressure ventilator and give full attention to the scene. The operability of the equipment must not be a mystery. Electronic “gimmicks” are of little use, because the concentration should be on the operation and the operation tactics and not in the operation of the equipment. Even without technical training, the equipment must be easy to operate. Regardless of whether it is a professional fire department or a volunteer fire department.
Blowhard PPV positive pressure ventilators are designed for low operating costs. On the one hand, the units offer very high mechanical quality combined with very long service life even in tough applications. Spare parts availability and corresponding warranty plans further reduce operating costs. Components of the highest quality are installed, such as the most modern and reliable battery technology. So that rescuers do not experience any surprises.
There is a decisive relationship between air speed, air volume and pressure at the scene of the fire. This determines the safety of the first responder and the speed at which the fire scene can be “exhausted” and subsequently extinguished.
Traditionally, the CFM value (m3/h) is used as an indicator to determine the effectiveness and strength of a fan, and often the values given are at zero pressure (AMCA). The CFM value (m3/h) is correct and important for making initial comparisons between different products. Nevertheless, it says too little about the real effectiveness and efficiency of the fan.
In order to be able to effectively “ventilate” distant sources of fire, it is not the air velocity or the volume that is decisive, but the pressure that is built up even over a long distance. Ventilation thus takes place through pressure differences between the interior of the building and the external environment.
Fans with modern airflow management maximize this pressure in a building to achieve maximum ventilation success. Thus, they do not rely on pure power, but on the smart use of available resources. Even though on paper the data is the same, fans with airflow management achieve greater efficiency in supporting and securing the operations team.
Whether a fan has airflow management can be recognized on the one hand by the rotor blade design, the inlet and outlet grilles and a corresponding electronic control system.
Smart management of energy and power is especially crucial for battery-powered fans. For example, maximum fan power is needed only briefly at the beginning of the operation to build up pressure in the building.
After that, it is advisable to adjust the fan power to the conditions at the site of operation. Fans with high-efficiency airflow management have decisive advantages here, because the reduction in output can be made without losing efficiency at the source of the fire. This translates into an exponentially longer runtime for a mature fan.
Fans without appropriate management are loaded much higher to build up the same pressure at the source of the fire. This translates into a shorter battery life.
