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.

Why Blowhard uses integrated batteries

Battery-powered devices of all kinds are on the rise worldwide. The products have long since gone far beyond DIY applications, and rechargeable batteries are increasingly finding their way into the professional sector. The development does not stop at overpressure ventilators or rescue tools. Today, a modern rechargeable battery can easily meet the correspondingly high requirements, provided that a few points are taken into account when purchasing and caring for it.

Integrated batteries require less space on the vehicle than replaceable batteries and their charging technology. They also allow higher power transfer and thus have less power loss at the electrical contact points and allow better thermal control of the batteries, which has a positive effect on battery life and battery runtime. They can ventilate longer.

In addition, built-in batteries manage to provide better protection against dust, smoke, and water, which makes the device more durable and reliable overall. Due to built-in batteries, the device is IP-67 certified and also meets the exact requirements you will encounter on the job site.

– Replaceable batteries require more space in the vehicle
– Replaceable batteries take time to replace
– Replaceable battery terminals have a performance-limiting effect
– Replaceable batteries do not allow thermal control

Good to know

For example, to achieve a fan output of 8,000 CFM (13,590 m3/h) with a BLOWHARD COMMANDO for 6 hours, you would need one battery charge. With a commercially available battery-powered fan with replaceable batteries, you would need to carry up to 8 batteries unless you temporarily charge them. If these batteries are charged in the meantime, it is about 2 batteries less with a charging cycle of 3 hours. This is because charging replaceable batteries with today’s battery and charging technology also takes longer than it takes to consume a battery charge in ventilation mode.

Developed in practice

For more than 10 years, Blowhard has exclusively manufactured PPV products for firefighters that exceed the industry standard. The current revolution is Blowhard’s High-Flow Jet Technology, the PPV fan that works as hard as you do.

Blowhard products are not created exclusively on the drawing board. Thousands of units are in use around the world, providing new knowledge that we apply to our products together with active firefighters. For an even more effective and safer operation.

Integrated battery or exchangeable battery?

With the large number of positive pressure ventilators, there are some devices that rely on the technology of an integrated battery. Other manufacturers focus on replaceable batteries. But what are the advantages of the respective technologies? Sure, a removable battery promises an infinite power source for your high-powered fan, at least on paper, but there are also some weighty drawbacks to this design. Positive pressure fans draw a large amount of power from the battery during operation, which must be transferred from the battery to the positive pressure fan. All components in the system must be able to handle this power demand. The battery must have sufficient discharge capacity. Cables and connectors must be able to handle the required power.

Replaceable batteries must provide this power via additional connectors, but these lose efficiency over time. As a result, the performance of your fan also decreases. The result is, for example, less fan power or less battery life and, as a result, batteries often get hot, which greatly shortens the life of the batteries.

Interchangeable batteries are subject to greater mechanical and thermal wear and do not always fit across all rescue equipment you carry on your vehicle. Replaceable batteries are nowadays regarded as consumables in common firefighting practice and are to be added to the equipment price over its years of use.

BLOWHARD Dual-Power eliminates the need for replaceable batteries

BLOWHARD uses integrated rechargeable batteries combined with the specially developed Dual-Power System. Dual-Power blowers can be operated with battery or in mains mode and are easier to use as well as more portable and compact than units with additional external charging technology for replaceable batteries.

When a positive pressure fan is used in battery mode, it may be necessary on rare occasions to ventilate beyond the capacity limit of the battery. In such situations, the PPV positive pressure fan must be able to run inline mode. It must be possible to change the power source to mains operation without complications. Two decisions can now be made with the power supplied from the mains.

Exclusive operation of the fan and thus maximum focus on mission success
Additional charging of the battery and thus reduced power for use at the fire scene

The selection of the second option makes little sense upon closer examination, as it minimizes the ventilation success at the fire scene. This creates a new and insufficiently plannable situation to which the first rescuer must react.

Charging electronics: BLOWHARD uses a charger already integrated into the unit and matched to the battery. The fans can remain plugged in on the vehicle with 220-240 V and the integrated charging electronics ensure optimal charging and life of your battery by balancing the battery and protecting it from deep discharges or overcharges, always keeping it optimally ready for use. A permanent coupling to the charging electronics is extremely important for the health of the battery. Care should be taken with external chargers to ensure that the charging electronics do not limit the maximum number of charging cycles. This may be the case if chargers do not correspond with the electronics built into the battery.

Energy switching: Another point of attention is the energy switching between battery and mains operation. It is important to know that the switchover is automatic and that the positive pressure ventilator does not interrupt its operation in the process. If ventilation is interrupted at any point during the operation and additional personnel action must be taken, the success of the operation will be minimized. Blowers that can seamlessly and automatically switch from battery to mains operation (and back) without interrupting ventilation are advantageous and save the first rescuer a lot of time.
