1. Positive pressure blower roof by the fire control system startup. 2. The motor starting current is generally run by the motor with a rated current of 2 times the square root of estimates. SJG inclined flow fan applications meridional acceleration theory Buying blower designed mixed flow impeller and the cone-shaped puff Jane blower housing prices, the fan airflow afternoon plane to accelerate, static pressure gradient decreases, thereby avoiding or reducing the air flow out of body improve the pressure coefficient and fan efficiency and reduce noise. SJG inclined flow fan pressure coefficient is higher than the axial fan, flow coefficient higher than the centrifugal fan, this unique aerodynamic characteristics, making it most suitable for compression and supply and exhaust ventilation duct blower company, and centrifugal fans and axial fans are often unsuitable for use in such a field station. At the same site conditions, with mixed flow fan SJG replace the low pressure and high pressure centrifugal fan axial fan, can significantly reduce the use of silencers measures. There SJG inclined flow fan blower machine number 12, 27 kinds of specifications. Wind coverage reached 100m / h an 50000m / h, hydrostatic coverage reached 20pa-l100Pa, provides users with a wide choice, the choice to meet the needs of different projects.
