Centrifugal fans with airflow rate of 4,650 to 9,700 (m³/h), with rectan-gular discharge area for installation in industrial and commercial venti-lation systems. According to the fire department codes and standards, the fire escape stairs must be positively pressed at the fire time. To provide positive pressure in the stairs usually fans with relatively low static pressure and high flow with proper operation and possibility of installation outdoor on the roof are needed. For this reason, Bostanchi Industrial Group has been developed positive pressure fans. These fans have a forward centrifugal impeller and two-way input. The motor is external rotor type and is located inside impeller. the case and impeller are galvanized and suitable for outdoor conditions. The motors are in two types of single-phase and three-phase and in the form of 6 or 8 poles.
