SJG inclined flow fan applications meridional acceleration theory, designed mixed flow impeller and the cone-shaped puff simple case, the fan in the airflow afternoon plane to accelerate, static pressure gradients are reduced, thereby avoiding or reducing the airflow off the body, improve the pressure factor and fan efficiency, reducing noise. SJG inclined flow fan pressure coefficient is higher than the axial fan, flow coefficient higher than centrifugal fans, this unique aerodynamic features that make it most suitable for pressurizing and supply and exhaust ventilation pipe and centrifugal fans and Axial fans are often unsuitable for use in such field units. Under the same site conditions, with SJG inclined flow fan alternative low pressure and high pressure centrifugal fan axial fan, can significantly reduce muffler and adoption. SJG inclined flow fan a total of 12 gauge, 27 kinds of specifications. Wind coverage reached 100m / h a 50000m / h, static coverage reached 20pa-l100Pa, provides users with a wide choice of transport fans to meet the needs of different projects chosen. Dezhou rich ventilation plant is a professional production of central air-conditioning end equipment manufacturers supporting. Products in full accordance with national standards, standard production, advanced equipment, technology and stability. Our main domestic large enterprises to do OEM OEM production, while direct customers located in the central air-conditioning and fire ventilation equipment installation company, according to user needs, design and manufacture of various types of specifications ventilation, central air-conditioning end and fiberglass products. By positive pressure blower to supply air to escape fire stairs, indoor smoke can not reach the stairs, to create conditions for people to escape. Positive pressure blower generally installed on the building roof blower, and the layers of the positive pressure valve linkage. Initial fire damper is opened strong blower, start positive pressure blower, so that stairwells, elevator hall in positive pressure (blowing state). Usually the layers in the building air shaft set louvers, window air do with different layers of the open air shaft, set single double, to ensure pressure; or a small blower outlet pressure, sometimes with manual and body and block sight, remote control device, can control the air supply. Transport fan, ventilation equipment Plumper (online consultation), Zhangye blower provided by Dezhou rich ventilation plant. Dezhou rich ventilation plant (www.frtfsb.com) (www.frtfsb.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Rich ventilation equipment in leadership with the staff warmly welcome all inquiries negotiations to create rich, ventilation a better future.
