Rule Industries 140 3-Inch Inline Marine Bilge Blower 12V 135 CFM

The Rule Industries 140 is a 3-inch inline marine bilge blower designed to deliver efficient, high-volume ventilation for bilges, engine compartments, galleys, and heads. Operating on 12V DC (13.6 Vdc nominal), this compact blower moves 135 CFM at open flow with a low current draw of just 2.9 amps, making it easy on your vessel's electrical system.

Key Features:

• 135 CFM airflow at open flow for powerful ventilation performance
• Slip-on inlet and outlet connections for standard 3-inch (76mm) ducting — no tools required
• Sealed motor shaft with front and rear shaft seals for moisture protection and long service life
• Corrosion-resistant nickel-plated motor housing built for harsh marine environments
• Low 2.9-amp draw with a 4-amp recommended fuse rating
• Quiet operation — lower noise output than standard bilge blowers
• Mounts in any position on any flat surface for flexible installation
• USCG 183.410 Compliant — ignition protected for safe use in fuel-vapor environments
• IMCI (CE) approved for international and US markets

The Rule 140 inline blower installs easily in tight spaces and connects directly to standard 3-inch marine ventilation hose. Its ignition-protected design meets U.S. Coast Guard requirements, making it a code-compliant choice for enclosed engine compartments and fuel storage areas aboard powerboats and sailboats.
