CEILING CASSETTE PM SERIES
A.6.1 FEATURES
● Indoor (Main) Unit In case of PMH-P2BA
CEILING
CASSETTE PM
1. QUIET AS A MOUSE AND AS INCONSPICUOUS AS ONE TOO, THE PMH-P SERIES IS AN ATTRACTIVE, LIGHT­WEIGHT MODEL THAT MOUNTS DIRECTLY INTO THE CEILING, BLENDING ALMOST SEAMLESSLY WITH NEARLY
FEATURES
ANY INTERIOR.
2. FRESH AIR INTAKE
Auto Air Swing Vane Disperses air flow up and down and adjusts the angle of air flow direction.
Horizontal Air Outlet
Filters Remove dust and pollutants from inhaled air.
Air recycled indefinitely can become stale and stagnant with air quality suffering significantly. Fresh air is the answer and it is for this reason that the PMH-P series takes in air directly from outdoors. This fresh air intake allows you to enjoy the comfort of crisp, refreshing air in the confines of your living or working space.
Air intake Inhales air from room.
Guide vane Air flow can be changed to horizontally by moving the Guide vane to the left or right.
3. LIGHT AND COMPACT
The main unit weighs a measly 14kg and the panel a mere 3kg. This makes the PMH-P series one of the lightest in the industry. The unit size is also quite small, having been standardized to a strikingly compact 854mm. All of this helps make the chore of installation and maintenance that much simpler and easier.
4. AESTHETICALLY PLEASING
Nothing ruins the look of a carefully decorated room more than a poorly designed, bulky air conditioner. With the PMH­P series, there is no need to worry. The unit mounts directly into the ceiling barely protruding into the living space for a pleasant, stylish aesthetic.
