Compact ducts provide
comfort cooling or heating for
small room applications.
Features include high efficiency
up to 21.5 SEER, heating at low temperatures down to
-5°F, compact design, quiet operation, a standard wired
remote control, and the ability to bring in fresh air.

High Performance Heating
Heating capacity at low
outdoor temperatures is
achieved by adopting a

Function
Long maximum combined piping length of 66’
and 49’ in height allow for versatile installations.
Flexible installation, either horizontal or vertical,
and low height enables compact soffit or cabinet
installation. These features make compact duct
systems ideal for commercial applications such as
offices, restaurants, convenience stores, motels,
dorms, in retrofit and new construction.
Field Supplied Filters Used With Compact Duct Units
Although Compact Duct units come with factory filters, when return
ductwork is used field supplied filters are more practical to use. They
can be installed at the unit or for more convenient servicing, in filter
grilles. See the guidelines to the right to determine filter sizes.
The chart includes CFM, external static pressure capability and a
typical filter size for each model. Filters are sized to keep velocities
and static pressure loss low. This will insure sufficient static pressure
is available for ductwork, fittings and supply and return grilles.
Alternative filter sizes with equivalent face
areas can be used. After deducting filter
loss, available
static pressure values are shown.
