Jetforce Airbag Technology:

A revolution in airbag technology, JetForce provides an added margin of safety to your avalanche tool kit.

The Jetforce is the first Avalanche Safety technology to use jet-fan inflation. This is a breakthrough system that draws air from the unlimited source of the atmosphere.

The Jetforce avalanche airbag system is dramatically improved for ease of use and performance over traditional compressed gas cylinder systems.

Battery-Powered jet-fan inflates the Airbag in 3.5 seconds, and then the 200L Airbag automatically deflates after 3 minutes to create an air pocket to aid in extraction.

Jetforce’s repackable airbag and fully rechargeable electronics system provide zero-cost user practice and travel-friendly performance.

The redesigned JetForce is not built into a backpack, it offers interchangeable booster systems in 10 litre, 25 litre and 35 litre capacity.

Activation of Airbag:

When wearing your Pieps Jetforce BT 35 Airbag make sure all straps securely fastened and the system is successfully armed with the LED is showing a pulsing green light. The airbag can now be deployed.

Grasp the Deployment Handle and firmly pull downwards to open the Release Flap that covers the airbag and turn the fan on.
The airbag will begin to Deploy Immediately. The fan will run at Full Power For 9 Seconds, followed by lower speed operation and Short Refilling Bursts for 3 minutes.
The airbag will deflate after 3 minutes and then automatically switch back to armed mode.
To interrupt the inflation/deflation process after the initial 9 second deployment period and return to armed mode, Press and hold the red power button for approximately 5 seconds.

Jetforce Airbag Filling Time

Fan timing is controlled by the electronics, here is how it cycles:

0-9 seconds - Mandatory Fill: During the first 3.5 seconds, the airbag fills 100%. For the next 5.5 seconds, the system continues to run at full speed for safety redundancy.
10-60 seconds - Active Performance: The system pulses between full speed and 50% speed. Since this is the most likely time to be carried by the avalanche, it is most critical to maintain full volume and recover from any possible tears.
61-180 seconds - Volume Maintenance: The system has 20s stand-by intervals between 3s full speed refilling pulses. The goal is to maintain the volume to aid in visibility and meet CE timing requirements.
181 seconds - Active Deflation: After 3 total minutes, the bag will automatically deflate. If partially or completely buried, this has the potential to create a large volume of air for breathing and/or extraction. If unburied, this simply helps repack the airbag quicker.

Ideal For:

Guides, forecasters and serious backcountry travellers, the Pieps JetForce BT 35 Airbag carries all the tools of the trade for backcountry professionals and features JetForce Technology. A revolution in airbag technology, Jetforce provides a travel-friendly added margin of safety to your avalanche tool kit.

The Advantages Of The Jetforce:

Easy air travel, little to no restrictions on the batteries as they’re no different than laptop batteries.

As many practice deployments as you desire, battery good for 1 to 6 full inflations depending on temperature and age, the battery is rechargeable.

No hassle with canisters.

Slightly lighter in weight than compressed gas offerings.

Automatic deflation cycle can possibly create airspace around the head in the event of a burial.

Specific to Black Diamond & Pieps design, airbag stuff-stows loosely after use, pack it in minutes with no folding necessary.

The fan is set to cycle on periodically during 3 minute inflation period per CE standards, this can overcome up to 7-inch tear in the fabric.

Jetforce FAQs

How fast does the bag inflate?

3.5 seconds for initial fill, which is as fast (or faster) than any cylinder system.

Where does the air pull from?

There are three locations that allow air to enter the fan.

The primary is the intake port located on the lower left sidewall of the pack.
The second is the entire backpanel of the pack is open cell reticulated foam that acts as both a filter and air intake.
The third is through the mesh lining of the airbag pocket itself, after the airbag has been activated.

Having three intake locations allows the system to get ample amounts of air despite any impediments like snow, clothing, or equipment.

Will the airbag be able to deploy from within the snow?

Through our experience with the AvaLung, we have done years of research to prove that the snow pack maintains large amounts of available air. We have designed the system to pull air from many locations around the pack, thereby reducing the concern that any one of these spaces could be fully blocked. Also, the fan runs about 3 times longer than needed to actually fill the bag, thereby allowing for the reduced efficiency when fully buried.

How fast is the fan?

60,000 rpm

What type of battery is used? And is there a temperature effect on the battery?

The JetForce battery is similar to the battery found in most laptop computers: a Lithium Ion. Our battery differs in one key aspect: it was engineered specifically to operate at very cold temperatures (-30C). The battery is sized to operate once at very cold temperatures even at the low end of charge levels.

How long does it take to charge the battery?

A fully depleted battery will need 8 hours for a full charge. As with all Lithium batteries, for the best battery life expectancy, we recommend the battery is maintained closer to full charge.

Is the Airbag mechanism interchangeable between Backpacks ?

The jet force is built into the backpack and is not interchangeable like the ABS system.

How long does a battery charge last?

A fully charged battery can last up to six weeks depending on use.

Can the system be turned off during deployment?

Yes, but only by intentionally pressing the power switch for 4 secs and only after the mandatory initial inflation phase.

Why does the JetForce system turn on and off during deployment?

The system cycles through multiple phases throughout deployment. Each phase is specifically tuned to optimize safety and battery life.

0-9 secs: Mandatory Fill During the first 3.5 seconds, the airbag fills 100%. For the next 5.5 seconds, the system continues to run at full speed for safety redundancy.

10-60 secs: Active Slide Performance The system pulses between full speed and 50% speed. Since this is the most likely time to be carried by the avalanche, it is most critical to maintain full volume and recover from any possible tears.

61-180 secs: Volume Maintenance The system has 20s stand-by intervals between 3s full speed refilling pulses. The goal is to maintain the volume to aide in visibility and meet CE timing requirements.

181 sec: Active Deflation After 3 total minutes, the bag will automatically deflate. If partially or completely buried, this has the potential to create a large volume of air for breathing and/or extraction. If unburied, this simply helps repack the airbag quicker.

Why deflation?

All existing airbags only work well in ONE scenario- if you are actively churned by an avalanche. We wanted to create something that offered the potential for increased safety if the slide came down from above or if the victim got caught in a terrain trap. By deflating the airbag, JetForce has the potential to create a large air pocket in a complete burial scenario.

Other benefits:

Easier to repack after practicing
Easier extraction of the victim after partial burial

By waiting until 3 minutes before deflation it allows the practicing user an opportunity to shut the system off before deflation in order to maintain battery life. In the event of a full burial, the time allows for the snow to set-up firmly before creating a pocket.

Why are you using a larger airbag?

Three reasons:

Maximize the effects of inverse segregation. All avalanche airbags work on the same principle, which states that in an avalanche, larger objects will tend to rise and smaller ones will tend towards the bottom.
Increased impact protection. A larger area of balloon around your head and torso help to prevent impact.
Maintaining effective volume. By starting with a larger volume, it is easier to maintain an effective volume despite punctures or tears.

What effect does this system have on beacons?

There is a very minimal amount of interference with beacons, but only when the fan is actually running and only within very short range.

What about airline travel?

Our lithium Ion battery is very similar to those used in most laptop computers and therefore follows the same general airline regulations. [Our experience has shown that the pack can be either checked or carried-on, but any extra batteries MUST be carried on.]

Why didn’t you incorporate the AvaLung?

While we still feel that the AvaLung is a great technology and could certainly aide airbag users, we were more concerned that having two devices on the pack’s shoulder straps would only confuse an unpracticed user. If someone wants to have both, we already offer the AvaLung II sling, which can be used with any backpack. Also, the automatic deflation has the potential to create the same amount of breathable air as the AvaLung.

What’s the status with field testing?

We have been testing this system for the last 3 years (lab & field testing). Like all BD/Pieps product, before anything is made available to the public it will have undergone rigorous testing in the lab, then in the field with in-house users, and then is released to out-of-house professionals and athletes for more field use. Intensive out-of-house field testing phase will start in earnest this winter.
