OPTIONS & ACCESSORIES
Lek-Trol™ Speed Controllers
Lek-Trol™ Speed Controllers permit unlimited
air control. They use solid state "quadrac"
circuitry and insure not only complete speed
range control and extra long life reliability but
also a savings in the cost of electricity. Lek-
Trols can be installed and connected within
the fan casing, permitting precise system
balancing.
Pilot Light
This amber colored light easily snaps into any opening in the CI-
Series grille. The light will indicate when the fan is in operation
and is ideal when fan is not interlocked with lights.
Brick Vents
Sized to replace multiples of standard size brick or concrete block. Made of extruded aluminum with insect screens, storm proof
features and a protective finish, they are superior vents and ideal for installation in masonry walls.

anywhere within the room. The sensor also offers adjustable
shutoff feature with delays of up to 15 minutes.
