Dometic Fan-Tastic FA25 Essential Roof Vent Fan with DryDock

Move the air.
Skip the sealant.

A 12" ten-blade fan on a five-speed motor, sitting on a base that stays bolted and sealed to your roof. Ventilate now, upgrade later — without ever reopening the hole.

Heat, condensation and cooking smells all end up in the same place: the ceiling. The Fan-Tastic Vent Essential moves them out fast and quietly, then reverses to pull cool evening air back in. Underneath it, the DryDock base does the part nobody enjoys — it takes the sealant, the screws and the roof penetration once, and keeps them.

One fan, two jobs

Flip the direction and the same blade either pushes hot air out or draws fresh air in. Pair it with a cracked window or a second vent and you get a controllable cross-draught instead of a stuffy box.

Seal the roof once

The base carries the sealant and the fasteners. The fan unit lives on top of it and lifts off. When you want a different model later, or a service unit goes in, the roof penetration never gets touched.

The cable entry is already in the roof

Two pass-throughs are built into the base, so solar leads, an internet antenna, a TV coax or exterior lighting can come inside through a fitting that’s already sealed. That’s a roof gland you don’t have to buy, cut for, or worry about later.

Details that show up on the road

Two cable ports, pre-sealed

Solar, internet, TV and lighting cable route through the base instead of through another hole in your roof.

Upgrade without resealing

The DryDock base stays bolted and sealed. Swap the fan without pulling butyl or drilling fresh holes.

Airflow you point

Reverse the blades to draw fresh air in or push stale, humid air out — five speeds either way.

No tools to clean it

The dome comes off by hand and the fly screen is magnetic — lift it out, rinse it, put it back.

Two lift arms, not one

A second arm takes the flex out of the raised dome, which is what stops the rattle on a windy night.

Built for the long season

UV-exposed parts and a simple, serviceable motor assembly made to run summer after summer.

Mounts to a standard RV roof vent opening on the universal DryDock base. Check the replacement guide below to confirm fitment against the vent you’re replacing.
