How do I choose a back pan?


Selecting a back pan is determined by the type of ceiling your office has and what size the neck is that attaches to the duct work.


If you have a standard perforated diffuser that has pins holding the screen in place a ½” from each corner of the back pan, you may be able to use this back pan for the installation.  If you have any other style diffuser you will need to buy one of our 3 back pan options.


Option # 1

The powder coated steel back pan is used in standard T-bar suspended ceilings. Prior to ordering you need know the round neck size that your duct work will attach to.  They are available in 6”, 8”, 10”, 12”, 14” and 16” round.


Option # 2

The fiberglass back pan is for use in T-bar suspended ceilings for multiple installations when you don’t know the neck size.   It can save time to buy the fiberglass covered steel back pan and take various sized start collars and duct sealant with you on the job.  Most contractors and facility managers can purchase start collars from their local HVAC supply house.  This back pan allows you to use start collars at the job site and cut the fiberglass to the neck size desired using tin snips or utility knife.  This type of installation normally needs an HVAC contractor or skilled facilities HVAC technician.


Option # 3

The Surface Mount back pan is for use in hard ceilings; plaster or drywall.  It is mounted onto the ceiling and the diffuser fits inside this back pan.

All the back pans allow the diffuser to hinge down for easy filter replacement.
