Ventilation and air conditioning systems for the current high and the flow often inadequate or insufficient flow is too large and the pressure of such a system does not match the fan case fan pressure, we "accelerated Meridian" design principles based on "quasi-ternary" theory and, The successful development of this specific speed between centrifugal and axial flow, pressure coefficient is higher than the axial fan, flow coefficient is more than a new kind of fan centrifugal fan. Thus, a user selection of a wider range, the system tends to be more reasonable match, so it is beneficial to the system and energy saving. The large number of practical applications show that the majority of users agreed that the product is the ideal energy-saving, environmental protection, simple, practical and ventilation equipment. Second, the characteristics of a compact, easy to install, reliable operation: The fan in the case of the same wind, air pressure than those in axial or centrifugal type size should be small, can be directly connected to the duct, horizontal or vertical installation, easy operation features. 2, low noise: The fan airfoil design through computer dynamic simulation can greatly reduce aerodynamic noise, air volume in the unit, the unit pressure working conditions, than A sound level can be reduced 3-5dB (A), while the case of low speed, obtain higher fan pressure. In the mining industry and senior civil ventilation system can replace or substitute low-pressure centrifugal fan without a lot of high-pressure axial fan muffler and 3, a wide range of application: This series points single-speed and two-speed two models, applicable according to different occasions, changing the angle of the fan is installed, change the number of leaves and transform revolutions reach their requirements.
