The Perseverance to Help Out

A couple of years ago I got to spend some time with my dad rock climbing in the North Cascades in Washington. My eyes were set on a very easy 5.9 big wall multi-pitch route called Prime Rib of Goat on the Goat Wall in Mazama. The route that we climbed was 1300ft of vertical cliff and one of the most popular beginner routes for getting into large climbs. Both my dad and I are knowledgeable when comes to climbing and were looking for a nice relaxing day on the wall. This is how that relaxing day turned into a crazy rescue…

The trip started out as any normal climbing trip would, an early 6 am flight as we had to get all of our climbing gear through airport security. Once the plane landed, we picked up our rental car and the gorgeous 3.5 hr drive up I-5 along the bay and straight on through the North Cascade National Park. Mazama is a small town with a population of only 158 people located on the East side the Cascades. Once we reached our destination and set up camp, we decided to do a little warm up on the wall to try and beat the stiffness and fatigue from a full day of travel.

The next morning, we woke up a little on the late side (around 7:30 am) got a light breakfast and set out for our goal the Goat Wall. The wall was a short 3 miles outside of town with a not so easy 1-mile hike in 95°F temperatures up a Scree field (basically hill of loose rock at the base of a mountain). Once we reached the base, we loaded up our gear onto our harnesses and started climbing to the first set of anchors (this is what is known as a pitch in climbing terms). Pitches 1 – 6 were fairly straight forward and easy going, water was rationed to ensure that we wouldn’t get dehydrated but at the same time wouldn’t run out of water.

By around 4:00 pm we had reached the halfway point at the top of pitch 6; this is where we ran into two people who were also climbing the same route as us but moving at a much slower pace. Luckily the were two trees that were growing on the cliff so we decided to take a small lunch break in the shade. Around a half hour later I shouted up the cliff to see if the two people had moved on yet; when I heard nothing we started climbing pitch 7. To my surprise the group ahead of us were still sitting at the top of pitch 7.

Turns out that the group had a 40 pound pack with them which was unusual for the single day climb on an easy route that could be easily terminated if needed. After another 10 mins of waiting we decided help them haul this pack of theirs up the wall. It was slow moving up to Pitch 8 and they had run out of water and our water was running low. By the time we had finally reached pitch 9 with all the people things had started to get worse for the group that we were assisting; fatigue and dehydration had brought them to the point of a mental break down.

At this point my dad and I decided to share the last bit of water we had with them and to turn around and bail on the last 3 pitches. It was a slow process moving back down the way we had come and try to keep the group calm; the sun and heat was really starting to take a toll on our bodies. Our lips were cracked and blistered and our mouths had quit producing saliva but we kept trudging on. A relief from the heat came around the time when the sun had set around the top of pitch 4 and from that time onward, we were descending down the cliff face into what seemed like a black abyss.

Finally, we were able to set foot on the ground and low and behold the friends of the group we helped had hiked to the base looking for their friends and they brought water we could all drink. We didn’t get back to the campsite until 1:00 am. The next day my dad and I decided to pack up and head to the coast because we were done climbing.

Super Air Knife’s Adjustability and Flexibility = Success

The EXAIR Super Air Knife is the most efficient compressed air knife on the market. We know this because we’ve tested them, and our competitors’ offerings, for performance, using the same instruments, controls, and procedures. We’re not going to publish data that we can’t back up, and that’s a fact.

They’re also ideally suited to a wide variety of applications – they come in lengths from 3 inches to 9 feet long (and can actually be coupled together for uninterrupted air flows of even longer lengths,) a variety of materials for just about any environment. But the best thing about our Super Air Knives is how you can adjust the air pressure and flow to complete a wide variety of tasks. You can adjust them in two different ways, Replacing or adding Shims, or regulating the incoming air pressure.

Changing out your shim!

A larger shim gap will give you higher flow and force from your Air Knife. Honestly, the 0.002″ shim that comes pre-installed in all of our Air Knives is perfectly suitable for most blow off applications, and appropriate air supply conditions are the first thing you should check for before going with thicker shims, but if you do indeed need a boost, a thicker shim will indeed give you one…here’s a blog with the video to show you how it’s done:

Another advantage to having a Pressure Regulator at every point of use is the flexibility of making pressure adjustments to quickly change to varying production requirements.  Not every application will require a strong blast sometimes a gentle breeze will accomplish the task.  As an example one user of the EXAIR Super Air Knife employs it as an air curtain to prevent product contamination (strong blast) and another to dry different size parts (gentle breeze) coming down their conveyor. For Performance at different supply pressures see the chart below.

EXAIR products are highly engineered and are so efficient that they can be operated at lower pressures and still provide exceptional performance!  This save’s you money considering compressed air on the average cost’s .25 cents per 1000 SCFM.

If you’d like to discuss altering the performance of your Super Air Knife, give us a call.
