[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - a square wall] DFBZ series fan axial fan with low noise fan motor for direct drive; machine made of square Blower, appearance, wall reserve square hole easy installation; outlet with a self-hanging blinds to prevent rainwater and natural wind outdoor indoor intrusion: a clear installation firm, small vibration, low noise, smooth operation, etc., is widely used in industrial and mining enterprises, civil building, gymnasium, animal husbandry, various entertainment wall exhaust. DFBZ-I type is adopted in the form of direct-drive motor rotor structure, DFBZ-II uses an inner rotor type motor, belt transmission structure form, DFBZ-III model with external rotor motor for direct-drive structure form. According to user requirements made corrosion proof type. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - axial fans] energy works when the impeller rotates, the axial gas from the inlet into the impeller, the impeller blades push by leaving the gas lift No high-powered fan, then flows into the vanes. Vanes will deflect the airflow into the axial flow, while the gas is introduced into the diffuser pipe fan technology to further the gas kinetic energy is converted to pressure energy fans, finally introduced into the pipeline work. Work axial fan blades similar to airplane wings. However, the role of which is to lift up on the wing and supports the weight of the aircraft, while the axial fan is fixed position and air movement. Cross-sectional axial fan is generally airfoil. Blades may be fixed position, and to be rotating about its longitudinal axis. Blades and the blade pitch angle or the air flow may be adjustable or not adjustable. Changing the blade angle or pitch is one of the main advantages of axial fan. Small blade pitch angles produce lower flow rate, while increasing the spacing may produce a higher flow rate. Advanced axial fan capable of changing the blade pitch (which is quite similar to a helicopter rotor) when the fan is running, thereby correspondingly varying the flow rate. This is called variable pitch (VP) axial fans. Blower, Tianjin Jinzhong Ji integrity for 15 years (certified), fans are provided by Tianjin Jinzhong Ji HVAC purification equipment.
