1. Features
1.1. New design, more modern and elegant appearance.
1.2. Convenient installation
--The ceiling type can be easily installed into a corner of the ceiling even if the ceiling is very narrow
-- It is especially useful when installation of an air conditioner in the center of the ceiling is impossible
due to a structure such as one lighting
1.3. Two direction auto swing (vertical & horizontal) and wide angle air flow
-- Air flow directional control minimizes the air resistance and produces wilder air flow to vertical
direction.
-- The range of horizontal air discharge is widened which secures wider air flow distribution to provide
more comfortable air circulation no matter where the unit is set up
1.4. Three level fan speed, more humanism design, meets different air-supply requirement.
1.5. Water proof by utilizing the absorbing plastic film on water collector
1.6. Easy operation. Auto-restart function, remote control and optional wire control method.
1.7. Low noise level plus compact size
--Shape of the blades has been improved to prevent noise caused by turbulence.

1. Features
1.1 Outdoor machine tightly packed, the bigger building type also needs one set outdoors machine only; Can
guarantee to construct the external appearance more simple and direct, and the gearing space need is
small, don't affect the room to adopt the light
1.2 Compressor start steady the start electric current is small, using the interference of the electric
appliances to the impact and others of the charged barbed wire net small
