What is an exhaust air jack?
The exhaust air jack lifts a vehicle using the gasses coming from your vehicle’s tailpipe. A hose attaches from your exhaust to the exhaust air jack under the vehicle. The air coming out of your exhaust fills the bag, and voilà! The car lifts off the ground. The exhaust air jack can stay inflated for as long as 45 minutes, though you should keep in mind that your vehicle will be idling the entire time. Air jacks come in different sizes and capacities and can lift vehicles as far as 30 inches (76 meters) from the ground. Exhaust jacks deflate in as little as five seconds when the job is finished, and the PVC-coated woven canvas folds up for easy storage.
Exhaust air jacks are very easy to use. They are available in various sizes, and the one for your vehicle depends on how large and heavy it is. No matter how big the vehicle, exhaust jacks lift it up the same way:
• Your exhaust air jack will come with a hose, one end attaches to the exhaust pipe and the other to the exhaust air jack.
• The exhaust air jack is placed anywhere under the chassis, so no jack points are necessary. Since it is basically a big balloon, there’s no need to center it under a particular spot on the car.
• About 30 seconds later, the exhaust air jack will be inflated and one side of the car will be off the ground. A one-way valve holds the air inside.
• Release the valve to deflate the exhaust air jack and lower the car.
The bottom of the exhaust air jack balloon like sack is protected from sharp stones, sticks or whatever may be under your vehicle by a PVC coating.
Uses of exhaust air jacks go beyond changing a tire on the side of the road. They can also be used to lift the front or rear tires so that you can put tire chains on two wheels at once, or to insert your recovery tracks under your wheels. They can even be used to lift trailers, boat trailers or basically anything with a frame and a couple of wheels. The exhaust air jack is also the best option when offroading to change a flat tire on rocky or muddy terrain, as a normal jack won’t do the job on uneven terrain. A high lifting jack will also work on rocky terrain, but on muddy terrain it will sink away, so better to use an exhaust air jack.
Safety when using an exhaust air jack
Manufacturers state that there’s no danger of pressure buildup in the engine because it takes very little pressure to lift the car. Doing heavy work while underneath a car lifted on an exhaust jack is not advised, but then again, it’s not recommended that you crawl under a car lifted on a regular hydraulic jack, either. When you need to work underneath your vehicle, a proper set of trestles or ramps should be used. Always ensure that you won’t damage any piping or sensors underneath your vehicle. Placement is crucial with any lifting device. Keep safety in mind at all times.
If you like venturing off into rocky mountains and deserted places, an exhaust air jack is a must have. When going into such areas, a flat is guaranteed some time or another and it will come in handy, believe me. The amazing thing about the exhaust air jack, as long as you have a running engine with an exhaust pipe and space for the bag under the frame, your exhaust air jack can be used. The exhaust air jack is not only for the hardcore offroader, but can also ease the process of changing wheels at your home.
