SeDeplacer RV A/C Vent Channel Retrofit Kit for Dometic Brisk Air 2, EVO & Blizzard — Pre-molded Foam + 2 Aluminum Foil Tapes

SeDeplacer's DIY RV Air Conditioning Vent Channel Retrofit Kit reshapes your RV's ceiling vents to boost airflow and duct efficiency for Dometic Brisk Air 2, EVO and Blizzard units.

This retrofit kit supplies pre-molded foam board and aluminum foil tape to convert existing ceiling vent channels into streamlined ducts that reduce turbulence and direct cold air where you need it. It’s a lightweight, low-cost modification intended for easy in-vehicle installation; no heavy tools or specialized cutting are required for most compatible Dometic and similar models. The result is improved circulation, quieter operation, and the ability to achieve the same cooling effect at lower fan speeds.

How does the retrofit improve airflow in older RV A/C systems?

The foam board channel smooths the interior path where air exits the unit, eliminating abrupt turns and cavities that cause turbulence. By guiding air into a narrower, consistent channel, pressure is preserved and more conditioned air reaches the living space instead of being dissipated inside the unit. That means more effective cold-air delivery and reduced strain on the blower motor.

• Pre-molded foam board forms a continuous duct through the ceiling vent.
• Foil tape seals seams to prevent leaks and maintain static pressure.
• Reduced turbulence improves airflow distribution and efficiency.

What models and RV situations is this kit compatible with?

This kit is specifically shaped for Dometic Brisk Air 2 (Duo Therm), Dometic EVO (Evolution), and Dometic Blizzard roof-top units, and can be adapted to several other Dometic, Advent, and Coleman systems with small modifications. Compatibility depends on ceiling adapter shape and available cavity depth; some installations require trimming or repositioning of the foam. The package includes materials for one unit and enough tape to complete the seal.

• Designed for Brisk Air 2, EVO, and Blizzard Dometic models.
• Modifiable to fit many Advent and Coleman units with minor alteration.
• Includes molded foam board and two rolls of aluminum foil tape for one retrofit.

How difficult is installation and what tools are needed?

Installation is intended to be a DIY project for anyone comfortable working in a ceiling cavity; no complex measurements or heavy cutting are required because the foam piece is molded to shape. Typical installation involves positioning the foam board into the vent channel, sealing seams with the supplied foil tape, and securing any edges. For some models you may need a utility knife, a straightedge, and a flashlight; basic mechanical aptitude is helpful.

• Pre-molded foam reduces measuring and cutting needs.
• Aluminum foil tape provides an immediate, airtight seal.
• Simple tools like a utility knife and screwdriver may be useful.

What materials and performance benefits should I expect after retrofit?

The kit uses lightweight, high-density foam board and aluminum foil tape for durability, insulation, and sound dampening. The foam’s insulating properties help keep conditioned air at temperature while the tape minimizes vibration noise and air leakage. Together they create a stable, quieter duct and help your RV A/C deliver a steadier stream of cooled air.

• Foam board offers thermal insulation and reduced airborne noise.
• Foil tape resists moisture and creates airtight seams.
• Improved duct stability and consistent airflow lower fan demands.

Who is this for: RV owners who want a cost-effective upgrade to improve cooling performance and reduce noise from older rooftop A/C units without replacing the entire system. It’s best for DIYers with Dometic Brisk Air 2, EVO, Blizzard, or similar units who can access the ceiling vent cavity and perform light modifications. If you prefer plug-and-play parts from an authorized dealer or your unit has uncommon dimensions, consult product measurements or a professional installer before purchasing.
