Air Handling Frequently Asked Questions
| Q | Who needs an air function? |
| A | Anyone who wants to move air through a fluorescent light fixture, or likes the "floating door" look created by a black reveal. |
| Q | What is an air handling unit? |
| A | A fluorescent lighting fixture which can be used to let air pass through it. When people refer to an "air handling" unit, they usually are referring to a unit which offers a wide range of possible air functions. These units generally have a reveal. Some examples of Columbia Lighting recessed air handling fixtures are the HC, P4, 45, 5PA and 6PA. |
| Q | What is the black reveal for? |
| A | The black reveal is our mechanism for getting air (other than extract) through the light fixture. To offer a full range of air functions, we dedicate a portion of the unit's structure for air passage. That portion is the reveal, the area we dedicate to air passage, a narrow strip on the back of the housing. Looking up at the fixture, it runs along the outside edge of either a door or louver. It is normally painted black and is often referred to as a "floating door." |
| Q | Do all air handling units have a reveal? |
| A | No. Some of our units allow heat extract only. Extract is an air function which does not require a reveal. A few examples of recessed units with extract only, without a reveal, include the VHC, P2, and 4PS units. |
| Q | Can I get extract only and a reveal? |
| A | Yes. You will need to choose a unit with full air handling capabilities. Some examples are the HC, P4, 45, 5PA and 6PA. |
| Q | Does Columbia Lighting provide the air diffuser or "boot" for air handling units? |
| A | No. Air boots are normally part of the HVAC package. |
