MODEL OVERVIEW
Model RCXII and RCXII-SF relief or intake ventilators feature low contour spun aluminum hoods for
an attractive appearance. They are designed to exhaust or supply air from or to an enclosed area
without the need for a power operated fan. Available in two styles, these fans range in sizes from 6-36.
The RCXII (curb) has a curb cap found on most roof ventilators and must be mounted on a roof curb
(sold separately). Model RCXII-SF (self-ashing) has an extra wide, at base that installed under roof
shingles and does not require a roof curb. Both styles come standard with a galvanized bird screen
Model RCXII and RCXII-SF rely on a difference in static pressure inside and outside the area to create
an airow through the ventilator from the area of higher pressure to the area of lower pressure. If the
enclosed area is under a negative pressure, air will ow into the enclosed area (intake). If the enclosed
area has a positive pressure, air will ow from it to the outside (relief).
These units can also operate as gravity ventilators, allowing air to ow from an enclosed area using the
"Stack Effect." The amount of air ow will depend on the temperature difference inside and outside the
area and the height difference between the ventilator and the outside air intake to the area.
