The High Pressure Canister and Aspirator responsible for inflating the Slide. 20140317_Overwing_Slide_deployed...from another site
When a Slide is activated, an aspirator and canister charged with Carbon Dioxide and Nitrogen must inflate the slide to full extension within 3.5 seconds. Any longer, and the unit fails the test and additional repairs need to take place. The inflation system contains the gases in a canister at 3000 PSI which is roughly 100 times the air pressure that you would find in your typical car tire. Interestingly enough, only 1/3rd of the inflation gases are used to inflate the Slide. The balance of the Slide is inflated with surrounding air through the Venturi Effect.
