Buying Guide
What to check before buying a 12V bathroom extractor fan for RVs or small spaces:
- Airflow needs: Choose 50 CFM or higher for small bathrooms; RV spaces may require more robust ventilation depending on size and moisture levels.
- Power and wiring: Confirm 12V DC operation, wire polarity, and available power sources (batteries or vehicle power).
- Installation profile: Measure duct size, roof opening or ceiling cutouts, and whether attic access is required or available.
- Noise level: For quiet environments, target 1.0–2.0 sones for home baths, or under 50 dB for RVs.
- Controls and features: Consider remote control, temperature sensors, and auto-on/off behavior if available.
- Durability: Look for rust-resistant blades and tested motors for longer service life in humid environments.
- Compatibility: Some blades and motors are RV-specific; verify mounting pattern, bore size, and shaft type for replacements.
