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.
Just a few years ago, it was unthinkable to use positive pressure ventilators in a fire. The concerns about adding fuel to the fire were too great. At best, positive-pressure ventilators were used to clear the scene of smoke after extinguishing the fire. The acceptance of positive pressure ventilators in strategic and tactical firefighting operations was, depending on the market, rather low.
Just a few years and many important experiences later, the picture has changed in many countries. The strategic and tactical use of high-performance ventilators is now well established, as the safety of first responders increases and the sources of fires can be better localized. A faster extinguishing operation is possible, which subsequently means more safety for the firefighter and the material.
And the development in the positive pressure ventilator sector continues. Thanks to their low weight, high performance, and compact design, battery-powered PPV positive pressure ventilators are now ready for use even faster and more effectively than gasoline-powered or corded positive pressure ventilators. As a result, many fire departments are looking at replacing their existing positive pressure ventilators with new battery-powered high-performance ventilators, which can sometimes enable the deployment of an entire fleet of positive pressure ventilators for strategic fire operations. In other words, more positive pressure fans in the same vehicle space as before. Battery-powered fans are thus much faster to set up than conventional fans. This has the effect of allowing firefighters to enter a building more quickly. It is probably undeniable that there are some questions regarding the use of battery fans. We at Vogt-CTE and BLOWHARD would like to shed some light on these issues.
As described, more and more firefighting operations are being carried out with the aid of one or, even better, several positive pressure ventilators. The advantages: rapid operational readiness, clearer visibility at the source of the fire, and cooling and safety of the firefighters far outweigh a somewhat accelerated fire. Putting a positive pressure ventilator in front of the door and not adapting the tactics to it does not work as a rule. The use of high-pressure ventilators requires a strategy and tactics adapted to the entire rescue operation. The strategic and tactical use of high-performance fans must be trained and practiced as a team. As a rule, there are fire rescuers assigned to the team for this purpose, and the responsibility lies with the incident command.
We now know that the proper strategic and tactical use of positive pressure ventilation is very important for the added success and safety that positive pressure ventilation should bring. But the best strategy and tactics are of little use if positive pressure ventilator technology is used that is not optimally tailored to firefighting operations.
The best way to explain it is in terms of airflow, the quality of which is of central importance at the scene. The efficiency of the airflow determines what positive pressure ventilator performance is able to penetrate the source of the fire. In this respect, a PPV positive pressure ventilator has to perform quite differently from conventional positive pressure ventilators. A good example of this is Blowhard’s High-Flow-Jet technology, which allows a concentrated airflow. To be compared with a laser in light. The shape and efficiency of the rotor blades are also crucial to the quality of an effective airflow. Only with the optimal technology is it possible to achieve different variants, such as blowing in or exhausting, or covering or not covering door lintels.
And ultimately, it has an impact on battery performance and service life. Inefficient airflow or rotor blades that are too large also mean a battery that is drained sooner. Or just more weight and volume that has to be moved because the battery has to be bigger. So, many people can build overpressure ventilators, and they can do it in an appealingly short development time. But only a few can develop a tool for rescue operations to meet the needs of rescuers.
Classic gasoline-powered positive-pressure ventilators have several advantages. One of the most important is their unlimited running time, provided that there is enough gasoline at the site. But there are also significant disadvantages. First of all, the weight plays a decisive role, as does the space required on the emergency vehicle. Which, as we know, can never be generous enough.
On the one hand, the heavy weight of a gasoline unit slows down operations, and far fewer positive pressure ventilators can be stowed on the emergency vehicle. In addition, the adjustment of the inclination of the airflow is often limited by the combustion engine. Further negative points are the handling of fire-hazardous operating materials in the vicinity of a fire source and also the additional environmental pollution and personnel exposure due to exhaust fumes during operation, which are sometimes associated with this.
The gasoline fan is therefore not always the first and best choice at the scene of the fire. If you want to use the overpressure fan under full load – in the sense of “a lot helps a lot” – for as long as possible, gasoline fans will of course help you. However, it is more advisable to use the ventilator in a smart way than in a power-sapping way. It’s always safer and gentler on women, men, materials, and the environment.
Aside from the fact that battery fan runtime is almost always sufficient, as we’ve read, there are many other factors that are more critical to your firefighting success than concern about battery runtime.
But yes. Batteries can drain. The battery only provides power for a limited time. In almost all cases, this power is designed to be absolutely sufficient, as a fire should also be extinguished after an appropriate amount of time. Nevertheless, there are some things you can do when dealing with a battery fan. First of all, it should be clarified whether it needs the continuous and full power of the fan or whether the power can be reduced in certain phases of the fire in order to maintain the overpressures at the fire scene. Pure wind speed and air pressure must be distinguished from each other. Manufacturers of professional high-performance fans offer appropriate training courses where this expertise can be acquired. Again, it is advisable to plan the tactical use of positive pressure ventilators in detail and to train the emergency forces and the incident commanders.
The use of spare batteries, it seems obvious, would be an alternative. However, this is almost never practiced in the field and is correspondingly susceptible in electrical connections. Dirt, water, and soot are addressed here. Plug-in connections sometimes tend to dissipate power, which has a negative impact on operating times. Charging during operation is also something you should check very carefully. Many positive-pressure fans reduce their performance during charging. It would therefore make more sense to have a wired operation at full power.
Accordingly, an integrated battery, ease of use, and a smart usage plan will benefit you more than pure power and performance. In addition, it is recommended to always treat your batteries with care and to take care of your health. Once not to mention checking what quality of batteries has been installed. In the case of a Blowhard fan, this care is ensured by built-in electronics without any hassle for you.
Basically, we humans always function in a similar way. Something that is heavy and clunky is less likely to be used than small, light, and yet solid products. If you don’t use complex products every day, you can’t operate them safely. Therefore, it can be said that ease of use, quick usability, and unconditional reliability are key drivers behind functioning and popular rescue equipment.
Buy the right one. Any “gimmick” you think you need can be forgotten or not work in the rush of deployment. During a mission, a simple and safe operation is what matters. Everything else is theory and is rarely or never needed. At the operation site, only one thing is important. The speed, simplicity, and ease with which the device can be brought to the scene. And, of course, that it works permanently and reliably
Battery-powered fans make your deployment safer and faster. There are no tripping accidents over cables and no problems with fire-hazardous liquids. Battery-powered fans can usually be brought to the scene by one person, and on the vehicle, there is usually room for 2 positive pressure fans in the space of a gasoline-powered fan. And they can be charged on the emergency vehicle completely without space-consuming additional chargers and with additional cables.
Blowhard makes the lives of rescuers easier and safer. Blowhard is designed for uncompromising use by professionals and heroes. No “gimmicks” and no false promises. Uncompromising, reliable, and robust. Vogt-CTE supplies products from Blowhard Fans one of the first suppliers to consistently rely on battery technology.
