Features: 1) Six specifications available: 315, 400, 630, 800, 1000,1200 2) Uniform air diffusing and adjustable air patterns 3) Easy installment, can also be connected or hanged by hooks 4) In addition to standard color of white other colors are also available 5) Widely used in the floor with height of over 3.8m 6) Blade is designed on the principle of fluid dynamics to provide the swirling airflow with speed, so that the air convection is increased due to long air supply throw and big coverage of jet 7) The angle of the blade can be adjusted in accordance with the working conditions to provide rotating air in horizontal, vertical and diagonal directions 8) Adjustable blades in our products can be adjusted by automatic temperature control, manual, electrical control as well as DDC remote control 9) Automatic temperature controller consists of temperature sensing units and springs can turn the rotational blades automatically accordingly to the temperature change of supply air, its key part is the temperature sensing unit, with a special liquid inside that can change its size accordingly to the temperature change, the size of liquid change can induce the turning of blades 10) No cable, maintenance, nor operation is needed 11) In summer: when supply air temperature ≤ 17°C,the spring moves out with the shrinkage of temperature sensitive device, and the thrust of the supply air will push the blades to the summer condition 12) In winter: when supply air temperature ≥ 27°C,the spring shrinks with the full movement of temperature sensitive device, and that will push the blades to winter condition 13) For fresh air: when supply air temperature is about 22°C,the spring starts to shrink with the small movement of temperature sensitive device, and with the thrust of the supply air will push the blades to the summer condition Packing: Specifications: Ø315, 400, 630, 800, 1000, 1200
