7 foot long by 10 inch diameter top loading air cannon
7 foot long by 10" diameter Air cannon with O-ring piston and top loading breech. This is a piece of equipment that should only be used by qualified, experienced Special Effects people. Expect a quiz on your qualifications if you want to buy this. We have 3 for sale.
We have three of these unique items and a spare piston. Note the black delrin friction pad on the complete unit.
36 Grade 8 bolts, an O-ring seal and 2-1/2" NPT Inlet on the top end of the cannon. This allows you to put the piston in from the top. Imagine the difficulty of lifting a 25-40,000 pound vehicle to insert the piston.
View down the bore of this cannon. If you have to do a cannon roll that needs this size cannon and are balking at the cost of this cannon, you do not have enough money in your budget to do the prep. We added 12,001 pounds of steel to a large bus to install these cannons and it took a crew of the finest high-skilled workers over 20 days to do the work. Bite this off only if you can chew the mouthful.
