Universal RV Roof Vent Fan 14x14 vs Dometic Fan-Tastic FA75 Roof Vent Fan

Buy the Dometic FA75 if you want a set-and-forget vent: rain sensor, automatic dome, thermostat and 10 speeds, backed by a 2-year warranty. Buy the FR360 if you want a simple, very quiet fan that drops into the same 14x14 opening for a basic install. The Dometic moves far more air and does more on its own, but it is heavier and more complex. The FR360 is lighter, quieter on paper and easier to wire. Owners of the Dometic line praise the rain sensor and build; FR360 buyers mostly report easy installs and quiet running.

• Choose the FR360 if you want a lightweight, near-silent 12V fan with four speeds and a straightforward DIY swap into an existing 14x14 opening.
• Choose the Dometic FA75 if you want automatic rain closing, thermostatic speed control, high airflow and a factory warranty.
