AIR FLOW inline fans are the perfect combination of Domestic & foreign advanced Technology on Design with Air Capacity of up to 950 CFM. Our Circular Inline Fan comes with CE Certification & with unique feature of Standard Thermal overload protection (S.T.O.P) Inline Circular Duct Fan: -The inlet & outlet sizes of our Inline Circular Duct Fans are the frame which saves the overall design & installation cost. Aerodynamic Impeller Design & special housing helps in reducing overall noise & vibration level. These Fans are compiled with ROHS requirement, Easy to install & can be installed by one person only. Impeller:-Backward curve impeller to achieve higher efficiency & lower noise level. Integration of impeller with external rotor motor is kept in mind while designing the fans. So that motor can be cooled by the airflow itself, which ultimately increase Product Life & Durability. Motor:-External Rotor or Motor passed CE, CCC Certification. The direct integration of motor with impeller i.e. direct driven Fans. The impeller & motor are combined to a whole with small install space, shed controllable & reset thermal protection device. It helps in reducing noise & vibration by keeping proper balance of current. Helps in achieving the optimum utilisation of power. Connection Box:-Connection Box is been designed by keeping convenience of connecting and disassembling of wire in mind. The box is made of fire proof material, which can prevent burning.
