Positive pressure ventilators offer fundamental advantages for first responders and firefighters at the scene of an emergency. Set up as a first-response device, the positive pressure ventilator generally ensures greater safety during operations and shorter response times:
BlowHard firefighting ventilators have been tested and comply with the new DIN 14963 standard for portable ventilation equipment.
Quickee – DIN14963-EM-A-1-1
Battery life is important for PPV Firefighting-Fans because every firefighter should decide for himself when he no longer needs the high-pressure fan. BLOWHARD relies on integrated high-power batteries because they enable a loss-free energy transfer, a longer running time of the fans, and a longer life than is possible with replaceable batteries. In addition to battery temperature management, the integrated battery technology also enables the IP 67 standard. The devices are therefore dust & waterproof and are therefore also ideally suited for tough firefighting operations.
The fundamental goals for every BLOWHARD Firefighting Fan are the highest and industry-leading performance values. Here, not only the battery, motor, and electronics used are decisive, but also in particular the aerodynamic 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. The decisive factor is how efficiently the fan is able to handle the power provided by the battery.
Performance without control is useless. This also applies to firefighting fans. Even the highest air volumes and the highest air pressure are of no use if they cannot be targeted and used efficiently at the point of use. The BLOWHARD High-Flow-Jet airflow management system takes advantage of the already high-performance values of BLOWHARD fans and directs them precisely to the desired location. It simply offers you more options and reserves. It makes BLOWHARD an unbeatable helper in fire and smoke management.
Not every location is the same. The BLOWHARD fan design allows you to continuously tilt the airflow up to 180 degrees and precisely adjust the airflow to the conditions at the deployment site. This stepless adjustment capability allows for a wide range of tactical settings and arrangements at the job site. BLOWHARD provides you with simple but highly effective and safe PPV ventilation, no matter what the nature of your deployment site looks like.
On the emergency site, every second counts. BLOWHARD units are designed to be deployed very quickly and with maximum effectiveness at the fire scene. Both, the lightweight and the small volume of the PPV ventilators are of crucial importance for rescuers. The units are light enough to be carried to the scene by a single person and take up little storage space on fire trucks.
BLOWHARD firefighting fans are designed and manufactured for use in the toughest fire scene conditions. Water, sand, impact, and heat make little difference to the BLOWHARD fans. No wonder, because they were developed together with firefighting professionals. Despite their lightness, no compromises are made on solid construction. The firefighter fans are suitable and tested for many years of use under the toughest firefighting conditions.
At the scene of a fire, every second counts. This applies both to the fire scene and to the rescuers as well as the possible victims. BLOWHARD high-pressure ventilators, which are indispensable in such rescues, are therefore ready for use extremely quickly. The firefighters’ concentration should be on the operation and tactics at the fire scene, not on the cumbersome set-up and operation of the firefighting ventilators. BLOWHARD fans are built in such a way that anyone can quickly set them up at the scene, even without explanation
As easy as that – Simply set down the BLOWHARD fan, align it and start the high-pressure fan, focusing full attention on the source of the fire. The operation of the equipment must not be a mystery. Electronic “gimmicks” are of little use, as concentration should be on the mission and mission-tactics, not on the operation of the equipment. Even without technical training, BLOWHARD fans are very easy to operate.
BLOWHARD PPV positive pressure ventilators are designed for low operating costs. On the one hand, the units offer very high mechanical quality combined with a very long service life. The fire department ventilators always provide you with appropriate reserves, which reduces the overall load on the ventilators. The availability of spare parts and corresponding warranty plans further reduce your operating costs. Components of the highest quality are installed which have been developed in-house and manufactured for this purpose. Only the most modern, reliable, tested, and certified battery technology is used. So that the rescuers do not face any surprises.
The High-Flow-Jet technology developed by Blowhard is an optimized jet pressure in combination with a higher air entrainment capacity of the air flow. This enables a correspondingly higher air performance of the unit with lower power consumption at the same time. The advantages are obvious. More efficient ventilation of the fire scene, more economical use of resources with increased safety for your rescuers.
The airflow is not only used to clear the source of the fire of smoke and gases for optimal visibility. Part of the airflow is used to seal at the air inlet, usually a door or window, to prevent ineffective ventilation and backflow. For this purpose, however, one does not want to use the airflow that the fan produces with appropriate pressure, but the ambient air that the produced air flow entrains or carries along.
If this “entrainment” is well solved, it leads to a higher pressure inside the building, since the force of the airflow can be concentrated on this. Conventional fans with nozzle technology can sometimes build up more pressure, but often have only a limited area at the point of use that they can cover. Other conventional blowers with cone airflow can cover large areas but have only a limited pressure that they can build up at the actual source of the fire.
BLOWHARD’s innovative High-Flow-Jet technology combines both and has been developed and continuously optimized for exactly these operations together with firefighters all over the world.
Traditionally, the CFM value (m3/h) is used as an indicator to determine the effectiveness and strength of a PPV 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 effectiveness of the fan at the remote fire site.
The air velocity alone is also not a suitable comparative value, because excessively high velocities can cause turbulence and the application site is not ventilated effectively.
More decisive than air velocity or air volume is the optimal and targeted interaction of these two variables. This is the only way that the overpressure resulting from the air movement can be created at the site of operation during successful ventilation. It is the pressure that effectively pushes smoke and fumes out of the room and thus the danger zone. BLOWHARD fans with High-Flow Jet technology maximize this pressure in a building to achieve maximum ventilation success.
BLOWHARD High-Flow-Jet technology not only relies on the pure power of the PPV fan but relies on the smart use of available resources. Even if on paper the data is the same, the blowhard fans achieve a higher efficiency in supporting and securing your mission team.
And the easiest way to find this out is with a comparison test. We will be happy to provide you with an appropriate demo unit.
