NOTICE
Specifications are subject to change without notice for further improvement.
All the product information has been carefully checked.
Part 1. Product Features
1) Low operation noise
---Streamline plate ensures quietness
---Creates natural and comfortable environment
2) Efficient cooling
---Equal, fast and wide—range cooling
Four-way airflow
3) The adoption of the most advanced 3- Dimensional Screw fan
---Reduces the air resistance passing through
---Smoothes the air flow
---Makes air speed distribution to the heat exchange uniform
3- Dimensional Screw fan
4) Improvement for easy installation and maintenance
---Little space is required for installation into a shallow ceiling
---Because of the compactness and weight reduction of the main unit and panel, all models can be installed
without a hoist
