Dometic Universal Air Distribution Box | 3314851.000 | Non-Ducted

Complete your Dometic non-ducted AC installation with the Dometic Universal Air Distribution Box — Non-Ducted (Part #3314851.000 / 9105304487). Genuine Dometic OEM ADB designed for non-ducted Brisk Air II, Penguin, and FreshJet air conditioning systems. Low-profile design with conveniently placed control knobs and washable filter support.

Older ADB Style — Universal Legacy Compatibility

This is the older-generation Universal Air Distribution Box — engineered for broad compatibility across the legacy Dometic AC lineup:

• Dometic Brisk Air II
• Dometic Penguin
• Dometic FreshJet (legacy compatibility)

If you're servicing an existing installation with the 3314851.000 ADB and want an exact match replacement, this is the correct part.

Prefer the Newer FreshJet-Specific ADB?

The newer-generation ADB engineered specifically for current FreshJet installations is the Dometic FreshJet Mechanical Air Distribution Box (9600028602). Same non-ducted twist-knob approach, updated design tuned specifically for the FreshJet series.

What This Does

The Universal ADB is the ceiling-mounted interface for non-ducted Dometic AC installations. It houses:

• Operation and control knobs — conveniently placed on the horizontal surface for easy access
• Air outlet vents for coach airflow
• Washable filter mounting (filter sold separately)

Non-Ducted Installations Only

Engineered specifically for non-ducted AC systems — RVs without integrated ductwork throughout the coach. Air is distributed directly through the ADB into the living space rather than through overhead ducts.

⚠️ Washable Filter NOT Included

Washable filter is sold separately. Look for Dometic part #3315333.003 for compatible replacement filters.
