Swisco 40-189 Automatic Safety Door Closer.

A quick learner from NJ says:
Will this prevent a exterior metal door from slamming shut caused by a cross draft?

This operator is made to close the door, not slow it down. I don't believe there is an easy solution to this problem. You must find out where the vacuum or draft is coming from and try to lessen the air pressure. Maybe a wind breaker, or air vent. If the door has a commercial closer on it, try adjusting the speed and latch adjustment. You say it is a steel door, so you may also want to check to see if you need to replace the bumpers in the jamb. They may look like our 79-018.
