The Vari-Flow™ linear diffuser are the latest in
state-of-the-art VAV technology.
The Vari-Flow™ linear diffuser is a VAV ceiling diffuser
designed for a grid ceiling system. It functions as an air diffuser, a zone of
temperature control, and a VAV box.
The Vari-Flow™ linear (VFL series) provides individual
temperature control for cooling at each diffuser adjustable from 70°
to 78° degrees Fahrenheit. This will provide
constant uniform temperature within a large office space or in smaller
individual offices, regardless of heat load conditions. The net result is
uniform comfort and energy savings as none of the conditioned space is over or
under cooled.

The VFL diffuser is totally self contained and self powered by
a thermal element. The thermal element has a long proven history of
reliability. It functions in the unit as the thermostat and "motor" to power
the unit. The principle of operation of the element is a basic and simple one,
that of thermal expansion when a substance changes state, in this case from a
liquid to a solid. The element uses a mixture of wax and copper powder for the
medium. It is blended to respond in the desired operating temperature range of
70° - 78° degrees Fahrenheit.
The energy provided by the thermal element is coupled to an
efficient operating mechanism to operate the damper on the unit.
Installation is as quick and easy as a conventional ceiling
diffuser because there are no electric or pneumatic connections.
