Ceiling Mount Type Ventilating Fan Introduction 11-12 DC Motor Series 13-14 Super Quiet Series 15-18 Standard Series 19 10
These fans are installed in the ceiling connected with ductwork, by which indoor air is exhausted either through the roof or the exterior wall. Since they are mainly mounted inside the ceiling, the interior is not damaged. Various types are available for different needs. DC Motor type provides a premium solution for both spot and whole house ventilation; Super Quiet type offers a quiet and comfortable environment to you; Stainless Steel type is suitable for high humidity places while Lighting type provides double enjoyment with its dual functions. General Features Quiet Operation These fans adopt distinctive design of Resonance- - Absorption Structure. It can minimize the transmission of noise from the blower to exterior, reduce the operation noise to incredibly low levels and accordingly create a tranquil and silent environment for you. By the Double Orifice Structure, noise is effectively absorbed and reduced between the double orifice and casing. gh Efficiency Taper blade design effectively controls the air turbulence surrounding the blade. That achieves the strong and smooth ventilating performance, as well as reduces the noise level, by whole of the blade. Seam-processed casing ensures strength and hermetic sealing. Reverse flow prevention shutter results in further improvement of air tightness. Energy Saving The advanced casing design, along with an improved motor, enhance the fan performance effectively. Energy saving is attained by reducing power consumption down to 35%. Easy Installation Wiring of power cord to product is pre-installed in factory, just connect the cord to power supply for operation. (Except 38 model and Stainless Steel Series) Cassette type discharge adaptor also facilitates installation of the product, as well as a connecting duct. ng Life The unique design of new motor, corporated with the welllubricated ball bearing*, reduces temperature rise that can increase the motor lifetime and prolongs the product durability. * Except Lighting Series and Stainless Steel Series. Easy Maintenance One touch louver allows easy installation and removal of louver by finger touch. 11
