Zephyr Transfan
Wood or coal burning stoves, gas
or oil fired space heaters and fire-
places do an excellent job of eco-
nomically heating the surrounding
space. The PennBarry Transfan is
now available to move that heated
air through partitions or ceilings to
other rooms in your home or office.
The Transfan spreads the value of
your stove or heater. It’s easy to
install, quiet and economical, and effectively moves heated
air to remote rooms.
Each PennBarry Transfan has an integral Lek-Trol™ speed
controller to modulate airflow. Capacity can be varied from 50
to 255 cubic feet of air per minute. Power consumed is less
than 60 watts making the Transfan a great energy stretcher.

• Fits easily between wall studs or ceiling joists
• Variable speed controller is built-in for individual
comfort adjustment

Compact Transfans Are Easy To Install
Installation Instructions:
1. Cut 12 3/4" wide x 10 1/4" high openings between wall
studs or ceiling joists (template provided).
2. Run 115/1/60 (house current) to the opening.
NOTE: The Transfan has its own built-in, on-off, variable speed
controller so a separate switch is not needed if the Transfan is located
within arm’s reach.
3. Measure the wall thickness and slide the telescoping
sleeve to its required depth. Standard Transfans fit open-
ings 3 3/4" to 5" thick. For thinner walls, add a frame
around the opening.
4. Place the Transfan in the wall and draw UL listed wire
through the bottom hole of the junction box. Make secure
electrical connection with two wire nuts and replace junc-
tion box cover.
5. Slide the Transfan into its permanent position (be sure
the grille that was shipped attached to the unit-with knob-
is facing the room into which airflow is to be directed)
and install the unattached grille.
