12 Inch Blower with 15ft Ducting

This Allegro Industries plastic blower ships with fifteen feet of ducting and a twelve inch diameter. It is built for ventilation tasks in recreational vehicles and similar confined spaces. The unit arrives new and ready to install.

Practical Limits of Flexible Ducting

The fifteen foot duct length sets the maximum reach between the blower and the target area. Longer runs or sharp bends will reduce airflow, so the installer must plan the route within this constraint. The plastic construction resists corrosion but is not rated for high temperature exhaust.

Twelve Inch Diameter Decides Fit

The twelve inch inlet and outlet diameter is the single specification that determines whether this blower matches your existing ductwork or opening. Measure the port carefully; a mismatch means the unit cannot seal or move air effectively.

Questions about this item

Should I choose the 12 inch blower with 15 foot ducting or a different diameter for my RV ventilation?

The 12 inch diameter with 15 feet of ducting suits larger RV air-moving tasks where high volume matters more than compact size.

What does the 12 inch rating mean once the blower is installed in my RV?

A 12 inch opening moves a large air volume per revolution, so the blower can push or pull air through the full 15 foot duct run without excessive restriction.

Does the 12 inch inlet use a standard RV duct flange or a proprietary connection?

The 12 inch inlet accepts common flexible duct secured with a hose clamp or tape, matching typical RV ventilation practice.
