Now offering Fire and EMS Hero Wipes
Starts instantly on battery power.
No wasted time searching for AC outlets (battery optional).
Sets up 2-6 minutes faster than other PPV fans.
Ultra portable, ergonomically designed to be carried by one person while running.
40 lbs. base weight, 50 lbs. with optional battery.
Quick and easy positioning in hard-to-reach places, works from 6 to 20 feet from a door.
Designed for high pressure to drive ventilation.
High velocity jet stream penetrates deep to build pressure and cool the structure.
Higher internal pressure drives ventilation to clear smoke from the structure.
BH-20 outperforms PPV fans rating at higher CFM. The ability to drive ventilation by building pressure in the structure results in air movement equivalent to most 15,000 CFM rated fans in real world conditions.
Two BH-20s fit in the space of one comparable PPV. With variable-speed motor control, the BH-20 can double as a PPV fan, saving valuable truck space and money.

Understanding Positive Pressure Ventilation:
Firefighters involved in PPV are suggested to study and understand fluid flow to understand Positive Pressure Ventilation.
- Always remember, pressure is required to drive ventilation.
- Once pressure is available, a Flow Path must be established to control ventilation.
When defining a Flow Path imagine opening and closing specific doors and window as increasing and
decreasing resistance to control the Flow Path.
- Imagining a maze with gates is a good way to understand more involved fluid flow. Lifting various gates
in the maze will allow a fluid to follow different paths. Opening and closing gates will affect the Flow
As various windows or doors are opened, air will flow through.
Large gates/outlets will allow more air through.
Small gates/outlets will restrict flow. More pressure will be required for equivalent flow.
Fluids will follow the path of least resistance.
Short and wide pathways that are direct will provide the least restriction.
Long paths with multiple gates and narrow pathways will increase restriction.
Added restriction will reduce fluid flow through a given path.
Define the Flow Path:
To control the flow of air through a structure define the Flow Path/Paths of desired air flow.
- Identify the desired/available ventilation path (which rooms, hallways, etc. need to be ventilated).
- Identify the ventilation point. Smaller outlets will require more pressure for ventilation. (window/door).
- Identify pressurization point to drive air into the structure (door or window).
Ventilation Sequences may be used to quickly evacuate specific points in the structure. Ventilation Sequences are uses to clear a structure area by area.
- Opening and closing specific doors and windows will redirect the flow path.
- Flow paths can be redirected to sequentially clear specific parts of a structure.
- The maze flow concept will help with this exercise.
To add fans, identify additional points of pressurization to drive air into the structure (door or window).
Note: It is not recommended to use high pressure fans with low pressure fans when structure pressure is high. Low pressure fans will not increase flow through the structure, they are more likely to act as a restricted outlet.
Understanding BlowHard Technology: The BlowHard BH-20 design is based on a Jet Stream PPV approach: A high velocity jet stream penetrates deep into the structure to build pressure. Higher internal pressure drives ventilation to cool and clear the structure.
BlowHard just Blows Harder and…yes that matters.
Expanding on the technology and benefits introduced in the BH-20, the Quickee is engineered to increase performance while taking up less space.
BlowHard expanded on its ErgoFold design to bring a more powerful, smaller, lighter, more maneuverable 20 inch fan, increasing the performance and efficiency of the firefighter. The solution is a more effective firefighting process.
Quick. Efficient. Effective.
In and Out.
Pushing the limits battery technology and fan engineering, BlowHard’s Commando brings you unmatched performance with a footprint and weight similar to that of the BH-20.
The Commando redefines battery powered PPV with its ability to outperform some petrol driven fans, yet light weight and ergonomic enough to be carried and set up by one person. Using BlowHard’s innovative streamlined HighFlow Jet Technology and advanced ErgoFold design, you can expect all the power and performance of gas-powered fans without the CO, only clean cool air. Transport and set up this beast up easily and quickly to get the job done in even the most challenging terrane. Take care of small residents, large residents, large halls, high-rise stairwells – the list is endless; take charge of it all and get the job done. The solution is an all in one fan in a manageable package.
