The depth or internal clearance of your PIAD is the distance as measured from the exterior surface of your enclosure to the interior surface of the PIAD Window.  A depth of 2″ is standard, while 3″ and 4″ depths are offered at slightly higher costs.

Please examine the devices you intend to cover to ensure you select a sufficient PIAD Depth, so the PIAD Door can close fully without making contact with your protected devices.  If you require a depth exceeding 4″, please contact a Best Purging Systems Sales Associate.
