Description

Commercial Filtered Supply Diffuser solutions help improve indoor air quality while providing precise airflow control throughout offices, schools, healthcare facilities, retail stores, and commercial buildings. The Comfort First Filtered Diffuser combines MERV filtration with adjustable 4-way airflow to reduce drafts, eliminate hot and cold spots, and create a healthier, more comfortable indoor environment.

The Comfort First Commercial Filtered Supply Diffuser comes with MERV 12 filtration as standard and is also available with MERV 14 filtration for environments requiring enhanced air filtration. Designed to fit standard 24″ x 24″ ceiling systems, this diffuser helps capture airborne particles while improving airflow distribution and occupant comfort.

This easy-to-install air diffuser works with any 24” x 24” drop ceiling with a T-bar grid system or Fineline system. A more efficient MERV 14 filter is also available. Whilst the CFFD was designed as a 2′ x 2′ air diffuser for drop ceilings it can also easily be mounted on hard ceilings thanks to our surface mount back pan.

Mounting Options

How do I choose a Backpan?

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 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 do not 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. The back pans allow the diffuser to hinge down for easy filter replacement.
