Jabsco Continuous Duty Flangemount Blower, 4 in, 115V AC, 250 CFM

Overview

The Jabsco 36760-0115 is a 4-inch continuous-duty flangemount blower for 115V AC ventilation systems, rated at 250 CFM. It is made for moving air through equipment spaces and other enclosed areas where steady AC-powered airflow is needed, including diesel engine room ventilation when the space does not contain gasoline fumes or other flammable vapors.

This blower uses an extended life induction motor with thermal overload protection and a reinforced thermoset plastic housing. The flangemount layout lets the discharge side mount directly to a flat bulkhead or exterior surface, which helps keep duct runs shorter and cleaner in tight machinery spaces.

Key features

• 4-inch flangemount blower with 250 CFM airflow for equipment space ventilation and general air circulation.
• 115V AC motor suits vessels and installations where AC power is preferred over DC blower operation.
• Continuous-duty motor supports longer ventilation cycles than intermittent-duty blower models.
• Thermal overload protection helps protect the motor during demanding operating conditions.
• Reinforced thermoset plastic housing keeps the blower body practical for marine installation areas.
• Slip-on inlet duct connection works with duct hose routed from the space that needs ventilation.
• Corrosion-resistant materials throughout help the unit stand up to damp marine environments.
• Not ignition protected, so it must not be used to exhaust gasoline fumes or installed where flammable vapors may be present.

Installation and setup

The blower housing flange should be mounted on a flat bulkhead surface, with the discharge port fastened directly to the mounting surface. The inlet side can then be connected to duct hose leading to the compartment or equipment area that needs airflow.

A location that stays dry and cool will help extend motor life. Keep the blower away from direct spray, deck wash, and unnecessary heat, and route ducting with as few restrictions as practical so the blower can move air efficiently.

Compatibility and safety

This is a 115V AC blower, not a 12V or 24V DC blower. Confirm that the vessel or equipment installation has the correct AC circuit, overcurrent protection, switching, and grounding arrangement before installation.

Because this blower is not ignition protected, it is not suitable for gasoline engine compartments, fuel spaces, or any area that may contain flammable vapors. For diesel-powered engine room ventilation, it should only be used where the installation matches the vessel’s safety requirements and the compartment conditions are appropriate.

Use cases on board

This blower is a practical match for boats that need continuous AC-powered airflow in machinery spaces, equipment rooms, or other enclosed compartments. It also suits dockside or generator-supported ventilation setups where steady air movement is more important than short intermittent blower cycles.

Maintenance and care

Inspect the blower and ducting periodically for loose fasteners, blocked hose runs, salt buildup, and signs of heat or moisture exposure. Keeping the inlet path clear and the mounting area dry helps preserve airflow and reduces strain on the motor.
