Which UV Lamp Do I Need For My System?

When service is needed for your UV ozone system, usually it’s only the lamp needs to be replaced. The ballast that powers the lamp is typically fine and can last a number of years before showing any signs of wear.

Below is a list of the common lamps that are used in our UV systems.

Note: If your lamp does not have any of the part IDs listed in this chart, you will need to refer to the model of generator or the lamp descriptions.

* These lamps are used for older versions of the Airwaves™ HVAC air purifier.

** On older versions of these sealed units, there is no indication on the data plate of the unit that tells you that the unit contains a sealed version of lamp. You can determine if your lamp is a sealed lamp by simply removing the lamp looking for a clear sleeve on the bottom end cap near the pins. See photo below.
