BLOWHARD-FANS ADVANTAGES

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.

CHARGING & POWER ELECTRONICS - DOES YOUR FIREFIGHTING FAN HAVE BRAINS OR JUST BRAWN?

What your high-performance fan brings with it in terms of design inefficiencies has to be made up for by the sheer extra performance. As with a gasoline engine running above its power limits, this is reflected negatively in the service life and in high service costs for the entire system. Wouldn’t it be significantly better, especially in the case of battery-powered overpressure ventilators, to use the available resources intelligently, nota bene, without having to have someone standing next to it all the time to constantly regulate the overpressure ventilator?

The effective engineering work on a firefighting fan is not apparent at first glance and is often built in under the “hood”. Addressed is, for example, the charging electronics, which always ensures an optimal state of charge of its battery. Anyone who has ever had to provide the batteries for an RC model or even just looks at his cell phone knows what it means to maintain a battery optimally. A built-in charging electronics take over this task for them, even if the overpressure fan remains plugged in on the vehicle.

Temperature management – Some like it hot, but batteries don’t!
We know that replaceable batteries often do not offer temperature management. Here, an integrated battery with appropriate charging, power, and temperature electronics offers a clear advantage. Cold, and much more, heat damages your battery permanently. With the high power consumption of a high-performance fan, hot batteries are not a rarity, but standard. Only with built-in battery systems and correspondingly smart control can the temperature profile be effectively controlled, to the benefit of an extremely long battery life. It makes more sense to measure the actual condition and temperature of your battery by means of the power electronics and to always be able to call up the maximum power.  

Now it can be estimated for the first time that a high-quality device with corresponding control electronics will be cheaper over the product’s lifetime, even if it seems to be somewhat more expensive at first. Replaceable batteries are clearly to be defined in the area of consumables since they are subject to thermal aging. The costs of additional batteries are to be added to the device price over the operating years. A favorable purchase price does not necessarily mean favorable operating costs.

BLOWHARD - HIGH PERFORMANCE BATTERY POWERED PPV FIREFIGHTING FANS AND VENTILATORS

20″ QUICKEE – Firefighting fan – When optimum air performance and flexible use at low weight are required.

Based on the proven technology of BLOWHARD’s successful BH-20 model, but with higher ventilation performance in an even smaller and even lighter package, our compact and lightweight QUICKEE firefighter fan is the most efficient and effective firefighter fan on the market, replacing purely electric fans thanks to its excellent performance values.

24″ COMMANDO – Firefighting Fan – Maximum ventilation power and substantial reserves for any tactical ventilation.

Our large firefighter fan model is for larger fire scenes or simply when pure power is needed or more reserves are required in fire operations. As a battery-powered fan, the COMMANDO is sometimes more powerful than some gasoline-powered fans and has the ability to replace these devices in the field. Yet the COMMANDO is so lightweight and ergonomic that it can be set up and operated by a single person. 

NEW – BLOWHARD ELEKTRO – Blowhard is the pioneer resp. the inventor of battery firefighting fans. Hardly anyone has more experience in this field of pressure ventilation. Nevertheless, the successful BLOWHARD BATTERY models are now also available as a PURE ELECTRIC version BLOWHARD ELEKTRO. The big advantage is the lower weight. All other performance values remain the same. Those who wish can easily upgrade their device with a rechargeable battery at a later date.

MAINTENANCE IS VALUE RETENTION. WITH BLOWHARD, BATTERY MAINTENANCE IS DONE BY THE INTEGRATED ELECTRONICS.

LiPo batteries offer many advantages in terms of energy density and possible charging speed. LiPo batteries cannot be charged and discharged an infinite number of times. At some point, the storable current capacity decreases because the materials built into the batteries change their physical properties. This loss process, triggered by the sheer age of the battery, is called degradation, or “aging” in the vernacular. In this context, “aging” means the loss of capacity and thus of runtime. Everyone knows the phenomenon that smartphone runs out of juice faster and faster after a few years. Therefore, the battery is also considered a wearing part. The reason lies in the chemical processes that take place in the battery during charging and discharging. In the process, the available lithium ions become fewer and fewer, and that inevitably leads to capacity losses in the battery at some point. However, a battery can age even if it is not used, e.g. in direct sunlight and the resulting heat.

Another major factor in the aging process, as we already know, is the current rates at which a battery is charged or discharged. Extreme discharge rates or charge rates put batteries under tremendous stress. In the case of firefighting fans, a fast discharge rate is given by the energy demand of the fan unit and, of course, also the desire to be ready for use again quickly by means of fast charging. This makes it all the more important to have power electronics that constantly monitor the condition of the batteries and protect them from unnecessary wear and tear without noticeably affecting the fan’s performance.

So aging is quite normal for a battery, nevertheless, as we see, there are some things you can consider that will slow down the capacity loss and give you a longer battery life. We now know that one of the most important things is a sophisticated electronic system like the one BLOWHARD uses. If no such electronics are on board you have to take care of the optimal battery management yourself. But be careful! Battery management is a complex process that requires some experience and some time. This time means money and resources that should be better available at the fire scene.

Good to know – “Boost functions
Actually, this is a great and possibly useful invention. But let’s take a closer look under the hood. We know that temperature control can hardly be realized with exchangeable batteries and therefore the maximum performance can never be accessed because the batteries are limited accordingly. The “Boost” function was possibly developed to circumvent this circumstance, which nota bene requires corresponding personnel attention.

What happens when the “Boost” function is activated? More energy is drawn from the battery for a short time and it gets hotter. The runtime and lifetime of the battery are shortened accordingly. It is better to use a device that can always provide the maximum power since it has the corresponding electronics for temperature control.

THE C-VALUE - THE CHARGING CURRENT AND THE DISCHARGING CURRENT OF A BATTERY

The discharge rate at which your battery can be operated provides another important indication. The “discharge rate” determines how much current may be drawn from your battery without damaging it. It is comparable to the “charge rate” when charging the battery. Devices with integrated battery and power electronics regulate this dynamically and independently and always to the maximum of what is possible and necessary for successful use.

BLOWHARD integrated high-capacity batteries (HCI) are inherently larger and experience significantly less load for the same discharge capacity (C). An HCI battery with the same capacity as two small batteries can provide the same runtime at the same power (for example, 40 minutes at 1200 W) with significantly less battery load, extending battery life.

It is often referred to as the C coefficient. Here, charging or discharging current is related to the maximum capacity of a battery in order to be able to compare batteries of different “sizes” more easily. A coefficient of 1C means that a battery is completely charged or discharged within 1 hour, a C coefficient less than 1 means that it takes longer than 1 hour and a C coefficient greater than 1 means that it takes less than 1 hour.

It is common to speak of a 1-hour discharge instead of 1C or a C coefficient of 1. A 2-hour discharge would correspond to 0.5C and a 10-hour discharge to 0.1C. This is also true for battery charging. The physical properties of a battery are retained for the longest time when it is loaded with low currents. This refers to both the charging process and the discharging process. The C value should not be too high during either process.


Good to know
Modern rechargeable batteries contain a huge density of energy. When used properly, the use of such batteries is considered safe. But this is only true as long as all users also handle them properly. For example, if lithium-ion batteries are handled or stored incorrectly, they can pose a safety risk.

  • Use batteries from certified sources
  • Only use the original charger intended for this purpose
  • Avoid electrical overloads
  • Avoid thermal overloads
  • Avoid mechanical damage

LARGER FANS ON LOWER POWER LEVEL INSTEAD OF SMALL OVERPRESSURE FANS ON FULL LOAD

Of course, you want to use the smallest positive-pressure ventilator in the field. It requires little space in the vehicle and is easy to bring to the fire scene. However, there is a lot to be said for the larger positive pressure ventilator, which also has more reserves and is more forgiving of less-than-optimal deployment tactics.

A larger fan instead of a small positive-pressure fan
A larger fan can thus help cover the increased power requirements in the field. Equipped with a large integrated battery, it can provide power comparable to that of gasoline-powered fans.

Large fans expand the range of applications
Large fan greatly expands versatility and usability in the field, enabling scenarios that were previously not possible with battery-powered firefighting fans. For example, the effective ventilation of large building structures and the successful pressurization of high-rise staircases to keep them smoke-free.


Too complicated. I prefer to choose the gasoline fan
Mobility and the ability to operate independently of additional power sources are critical in the fire department today. This is because the environment and challenges are unknown or unique for each operation. This makes mobile fans, which are offered today, an attractive helper. Today’s battery-powered fans are already on par with gasoline fans in key areas and outperform them in many important ways.

Example: The safety concerns of gasoline-powered fans are associated with increased CO levels, as well as portability and storage requirements. The ease of use and minimal maintenance requirements of battery-powered fans are clear customer requirements today and are here to stay. The high-power density batteries available today also easily provide the power needed to operate a PPV positive pressure fan and a successful fire mission.

This expands the application possibilities of a battery-powered high-performance ventilator to include operational scenarios that were previously not possible. For example, the realistic ventilation of large warehouses and the successful pressurization of high-rise staircases.

  • Cold start properties
  • Increased maintenance requirements
  • Increased space requirement
  • High noise emissions
  • Exhaust gases produced
  • Flammable liquids
  • Increased weight
  • Insufficient airflow positioning
  • Easy to refuel
