1. OPTIMAL PERFORMANCE AND EFFICIENT MAINTENANCE
(1) PEACEFUL SILENCE THROUGH WHISPER-QUIET OPERATION
This top quality floor-standing model guarantees near-silent operation through a newly developed low-noise fan. Air-duct
design has also been optimized through the adoption of microslit fans. Perfect for shops and office meeting-rooms.
(2) LONG LIFE FILTER
The long life filter allows 2,500 hours of maintenance-free operation in office environments not so dusty.
(3) SMOOTH REMOVAL
An open grill system permits filters to be removed smoothly and easily.
(4) EASY CLEANING
Dirt can be cleaned off simply because vanes are flockless.
2. INSTALLATION TIME GREATLY REDUCED
(1) EFFECTIVE PIPE CONNECTION
Raising the pipe connection position facilitates pipe arrangement, thus shortening installation time.
(2) CONVENIENT WIRING
A raised wire connection position means that wiring work can be conveniently implemented.
(3) WEIGHT REDUCTION
The use of plastics as assembly materials has realized a reduction in weight of 22kg. (PS-5 GJSA 72kg ➔ 51kg)
(4) PIPE DIRECTIONS
Pipes can be installed in four directions (rear, left, right, and bottom sides.)
