Rule In-Line Bilge Blower - Ignition Protected Ducting Blowers, Available in 3" and 4" Ducting Sizes

The Rule In-Line Bilge Blower line clears explosive fumes and moisture-laden air from engine compartments and bilges before startup, moving fresh air through the ducting run to keep gasoline vapors and gas fumes from accumulating around the engine. Built with a corrosion resistant, nickel-plated motor housing inside a durable plastic body, these blowers mount easily to any flat surface and connect with simple slip-on ducting fittings, making them a straightforward upgrade or OEM replacement for boats that need reliable, ignition protected ventilation. Choose the Rule 140 for standard 3 inch ducting runs at 135 CFM, or step up to the Rule 240 for larger 4 inch ducting and 235 CFM of airflow on bigger bilge compartments or longer duct runs.

Sizes & Options

Match the blower to your existing ducting diameter and bilge volume. The Rule 140 is sized for 3 inch ducting and moves 135 CFM, making it a direct fit and replacement for Jabsco ITT-30480-0000 installations. The Rule 240 is sized for 4 inch ducting and moves 235 CFM, suited to larger engine compartments or setups already running 4 inch duct hose. Measure your current ducting diameter before ordering, since the two models are not interchangeable without also changing the ducting and connections.
