The MAXXFAN Dome is a compact 12-volt exhaust fan for RV bathrooms, showers and other small spaces. It differs from a conventional 14 × 14-inch roof vent: the Dome is designed for a 6¼-inch-diameter wall or roof opening. MAXXFAN Dome Plus models add LED lighting around the interior garnish; the non-LED Dome models have a different garnish ring and small-parts package.

Exterior guard and lift lid
The guard protects a vent installed in the sidewall; the lid opens manually.
Fan blade and motor
The exhaust unit moves air out through the 6-inch fan opening.
Screen and sleeve
The screen can be removed for cleaning; the sleeve fits the specified roof/wall thickness.
Garnish and handle
The interior trim and lid handle complete the installation; LED garnish belongs only to Dome Plus.
Component identification only; the manufacturer's separate illustrated instructions show actual mounting positions.
Before replacing a complete fan or an individual part
- Read the full model number on the fan base, visible after removing the screen, or check the original installation documents.
- Measure the actual circular roof or wall cutout; do not substitute for a 14-inch square roof vent without appropriate reconstruction.
- Confirm the 12V fused electrical circuit, roof/wall thickness, wiring route and weather-sealing requirements.
- For a wall-mounted installation, follow the manufacturer's guard orientation and mounting instructions.
- Disconnect 12V power before removing the screen, motor, blade or LED garnish. Inspect all seals and test operation after reassembly.
