Thanks for listening! I’m glad you found the information useful.
The requirements for the door are:
- Must operate with a maximum pressure of 5 lbs
- Must close from 90 degrees open to 12 degrees in 5 seconds maximum
You can use a stopwatch and a door pressure gauge to check the operating force. You can order a gauge here: http://www.hmc-international.com/dpg.htm
Thanks! I hope this helps.
