BLOWHARD Charging Electronics – Easy Charging
Always charge or discharge a battery in the perfect way. Most of the time, the wrong treatment results in decreasing battery life. An intelligent charging electronic, which takes over this task, therefore preserves your battery, extends your life span, takes over the battery and charge management, and additionally ensures short charging times on the fire truck. This all happens automatically when the BLOWHARD fan is connected to a mains socket and completely without additional and space-consuming external chargers.

In the BLOWHARD pressure ventilator is built everything is needed for a long and carefree operation. Only 230V is plugged in on the vehicle and everything else is done by the firefighting fan itself. There is no need to carry additional batteries and equipment. There is no mess with cables on the vehicle or uncertainty about which charger is the right one for which battery, as well as no danger of physical damage to removable batteries.

BLOWHARD Power Electronics – Always Maximum Power
The power electronics allow you to always and automatically have full power available at the point of fire. It also ensures maximum battery life. Why? Through optimal temperature control! The battery temperature is measured and the firefighting fan power is always kept at the maximum possible level. Battery overheating is one of the main factors for short battery life.

Some manufacturers have additional turbo buttons to increase the power to maximum values. Turbo Buttons are usually only installed because the battery has no temperature control and therefore the normal power must be lower and cannot be dynamically controlled by temperature control as with BLOWHARD. With continuous maximum power, the battery would therefore simply be defective after prolonged use, because it would overheat.

When operating the device, care should be taken to ensure the simplest possible operation. Operating a panel or buttons that are too small or complicated menu navigation can cause problems for firefighters in hectic operations. Almost always firefighters work with gloves, which of course limits their capabilities somewhat. In the field, fast and simple operation is what counts.

BLOWHARD Dual-Power – Switch with ease
Blowhard firefighting fans can seamlessly switch between battery and mains power without interruption, requiring no battery changes and minimal attention during operation. Every BLOWHARD fan can also be operated as an electric-only version. Not every fan has this capability and sometimes requires appropriate attention from the firefighter when transitioning between these modes of operation.

Complex functions, which have to be operated by first responders, unnecessarily complicate the operation. For example, wake-up functions for pressurized ventilators make operation more complex and often require increased attention to the apparatus

BLOWHARD Large Battery – Big is Beautiful
BLOWHARD uses the largest batteries possible to avoid high load spikes and therefore temperature spikes during power delivery. The power consumption and power output of batteries is limited. If you go to the limits of the battery, its life will be shortened. If you choose a large battery, you can avoid this peak load. This greatly extends the life of the integrated batteries.

Exchangeable batteries are also often problematic and are not used by BLOWHARD for good reason. On the one hand, the connectors lose and prevent the transfer of maximum power. On the other hand, the batteries cannot be run at the power limit because very often there is no temperature measurement in the battery. The result is short battery life cycles and increased operating costs. Additional batteries on the vehicle mean a safety risk. This is especially true if the batteries may be damaged. Replaceable batteries can be damaged more easily than built-in batteries, which enjoy certain shock protection in the device.

BLOWHARD fan design – A good and solid construction
The rotor and ventilation grille of BLOWHARD firefighting fans have been specially designed for firefighting tasks. They guarantee a maximum build-up of air volume and air pressure with minimum energy consumption. The reason: With a battery-powered fan, only limited amounts of energy are available that must be used efficiently. If the fan has an inefficient fan unit you need a large fan battery and the weight increases.

BLOWHARD High-Flow Jet – Power without control is useless
BLOWHARD High-Flow Jet airflow management combines the advantages of jet airflow with those of cone airflow. As a result, the units offer firefighters a range of application options with appropriate reserves. It is precisely the reserves in the operation of a pressurized ventilator that are crucial and ultimately ensure greater safety and freedom of application in operational and tactical firefighting operations. This also applies in particular to air performance.

The only question is what to compare in terms of air performance. Often different things are compared here. What is really measured? The direct airflow or the generated airflow? How long can the firefighting fan really deliver this power at full load? Most name and market the higher generated airflow value, but can only maintain this over a very short time – Desired clarity brings here the new standard DIN 14963 – BlowHard firefighters fans were one of the first and few tested and comply with the new standard DIN 14963 for portable ventilation equipment. The new standard promises a much better comparability of the firefighting fans. Such a standard was missing before. The methods used for testing also left a lot of room for interpretation and could hardly be related to real conditions in practice.

BLOWHARD Lightweight Construction – Just Ruggedized
The BLOWHARD firefighting equipment design was developed together with firefighters in the field and is characterized by extremely high load capacity with low weight and equipment volume. The low weight is not a direct result of low material usage but is the consequence of a well-thought-out overall system. This includes the design features as well as an optimal fan unit and a harmoniously matching battery.

But what is really Ruggedized? If strong-sounding materials are used? Or rather when the pressure ventilators have been tested and improved in tough use? For example, steel and aluminum should be used where it makes sense and not because it is cheaper to produce than a plastic injection mold. Metal can bend and cause permanent damage to the firefighting ventilators if used in the wrong place, and non-heat-resistant plastic can melt and ruin the application.

BLOWHARD quick connectors – With speed in action
BLOWHARD firefighting fans are easy and quick to use. The important thing is to manage the firefighting operation in the best possible way, not your firefighting fan. No one wants to allocate valuable firefighting resources just for managing the fan units. Strong pot magnets, for example, enable BLOWHARD ventilators to quickly attach accessories such as water rings or hoses within seconds.

BLOWHARD Ergo-Fold – Wherever you like
The airflow of a BLOWHARD firefighting fan can be adjusted steplessly and easily by up to 180 degrees. Ergo-Fold thus enables firefighters to adapt the fan to any operational situation and thus ensure optimum pressure build-up in buildings. No matter if it is a staircase or the pressure build-up in a basement compartment. This is done in a simple, intuitive, and stepless way, even in inaccessible locations.

BLOWHARD wheel set – Freedom on wheels
Wheels and handles should not hinder operation and should not take up space on the application vehicle. Nevertheless, you don’t want to carry the fan to the job site forever and prefer to save your strength for the main tasks ahead. The wheelset for the BLOWHARD Commando can be folded away, including the handle, saving important space for additional equipment on the Truck.

BLOWHARD Protection Class – It’s still all there
Things usually get dirty during operations. Extinguishing water, dust, dirt, and, above all, aggressive fumes are not uncommon. Not every firefighting ventilator can handle these conditions equally well. This is exactly where it is decided whether your investment in pressure ventilation has paid off. Do the devices break down or not? BLOWHARD firefighting fans are protected against dust and water at the IP-67 level, and even standing in water usually doesn’t bother them. The result: less need for service and cleaning and thus low operating costs
