Air pressure for the TrailAir pin boxes such as # LC328484 can range from 20 to 120 psi. There isn't a specific amount of pressure you have to use. Instead it is recommended to inflate the air bag to maintain a level ride height but do not inflate the bag over 120 psi.

Step 11 of the installation details (which are linked)

Inflate the air bag with only enough air to raise the pin box to the ride height mark on the front of the shock absorber with the truck and trailer at rest.

Overinflating the air bag could cause it to burst and cause some serious injury to you or those around you.
