FEATURES/BENEFITS (cont)
INDOOR AIR QUALITY (IAQ)
The Quality of Building Air is Improved as the DuraPac Plus
series utilizes certain key features that assist in improving
indoor air quality. A sloped condensate pan eliminates possible
biological growth in the rooftop unit. A face-split evaporator coil
(090-150 sizes) design proves effective in removing additional
moisture from the supply air. Two-in. filters are standard in all
rooftop units and an optional filter status sensor is available.

SERVICEABILITY
Standardized Components for the complete DuraPac Plus
line of products are found in all safety devices, condenser-fan
motors, evaporator-fan motors, and control boards, while the
gas sections use common inducer motors, limit switches, and
rollout switches. This allows for greater inventory control, famil-
iarity of parts, and fewer stocked parts.
