Actuator on a steel door

[ttuterry]

We currently have an actuator that is attched to each door of two very large swinging steel doors. They are attached right above the top hinge on each door. These doors are approximately 6 ft wide. There is normally a differential pressure in the rooms that the doors seperate, but sometimes for whatever reason the pressure is the same in each room and when this occurs the doors do not shut all the way. We were thinking that the actuators should be moved to possibly the center of the door instead of over the hinges, and possibly even moving the actuators out away from the wall and attaching them to the door at an angle. I am in civil so i dont know too much about actuators but i do know that it seems like having an actuator on the edge of a door doesnt seem to make sense. Anyone have any suggestions? Thanks.

Or you could figure out what "whatever reason" is, and fix the problem with the air system.

"fix the problem with the air system"

I wouldn't assume there to be a 'problem'. Maybe the AC isn't running because it doesn't need to.

Regarding the door closure, I would think moving the pivot point away from the wall would be the solution. Although, this will change the stroke length depending on where you move it to.

Isn't 2/3 of the way from the hinge the usual preffered position when possible?

That said I think a lot of actuators I've seen are nearer the hinge due to the length of stroke issue.
