Innovative Solutions ProGuard DXB 100 Replacement PCO Cell & BPI Kit (Late Model Replacement for Serial Plate Number 3365)

What is included in this DXB 100 replacement PCO cell kit?

This kit includes the replacement PCO cell for the ProGuard DXB 100 — the titanium catalyst honeycomb with UV bulb that generates the unit's active sanitization. This is the late-model version matched to units carrying serial plate number 3365 — check your unit's serial plate before ordering to confirm you're getting the correct match.

How do I know I'm ordering the right cell for my unit?

Flip the unit over. There's a four-digit model number on a sticker on the back of the housing — not on the cell itself. That number determines which cell kit matches your specific unit. If you're ordering through ProGuard directly, providing that number lets them match it against their internal spreadsheet; when ordering through Hydrobuilder, check the listing title against your unit's serial plate to confirm the right match.

How often should this cell be replaced?

Annually. The cell is what generates the sanitization — it's a required yearly maintenance item, not optional, to keep the unit performing at full effectiveness.

What happens if I install the wrong cell for my unit?

Cells are matched to specific unit generations and model numbers. An incorrect cell may not fit or perform correctly — if you're unsure which cell your unit needs, confirm the four-digit model number on the back sticker before ordering.
