Applications (Cont.)

The VTAC unit provides whisper quiet operation while

delivering maximum airflow required for proper air

circulation. Separate indoor and outdoor fan motors

further reduce operating sound levels and costs.

The heavy gauge construction of the chassis and cabinet

minimizes vibration for quieter operation. Vibration iso-

lators on the rotary compressor keep it running smoothly

and quietly. The unit bulkhead is fully insulated to

decrease outdoor sound transmission.

• Islandaire VTAC units are built with durable

quality components designed for continuous

operation in all environments.

• The outdoor fan motor is totally enclosed,

preventing damage from moisture and debris

introduced by extreme weather conditions. Both

indoor and outdoor fan motors are permanently

lubricated for extended life.

• Electrical components are located on the indoor

side of the wall protecting them from driving rain

and humidity.

• The compressor is a reliable, high-efficiency design

rotary compressor. It is hermetically sealed and

built for continuous operation.

All Islandaire VTAC units have special corrosion

protection that can help dramatically extend the life

of the unit. Listed below are just some of the compo-

nents that feature corrosion protection:

• Base Pan - The base pan of the unit is

constructed of 18-gauge galvanized steel with

powder coat paint finish to protect it from the

elements.

• Condenser Fan Blade - Constructed of strong

engineered plastic that has excellent flame-

resistance and dimensional stability over a

wide range of service temperatures.

• Condenser Fan motor - Specially coated by

the manufacturer to resist corrosion (optional).

• Compressor - Protectively-coated exterior to

enhance equipment life and performance.

• outdoor louver - Made of aluminum,

etched and anodized for maximum corrosion

protection. Available in various architectural

styles. Can be painted in a wide choice of

colors.
