Tech Spec

YFIAM-D Technical specifications

Fan Type
The fan shall be the axial flow fan with tubular structure. The drive type shall be direct-drive.

Quality Standards 
The fan shall be tested in accordance with AMCA Standard 210 and 300. The manufacturer must own the production license for industrial products and ISO9001 quality system authentication.

Impeller shall be variable angle vane axial wheel to meet the needs of the diverse conditions optimization selection. Vane and hub shall be made in cast aluminum which should be adopted by whole molding mould to ensure the strength of the limit of the tolerance 120% speed and improve the structure reliability and the security of the operation. Vane type shall be the wing to own higher aerodynamic efficiency. The fan shall keep stable airflow and low noise at maximum speed. The impeller shall be statically and dynamically balanced to Level G2.5 as per AMCA204 standard. The fan shall be avoided performance degradation caused by slide of operating point effectively.

Fan Housing
Fan housing shall be constructed of continuously welded cold rolled steel panel with epoxy surface, the flange shall be integrated machine shaping.

The impeller shall be directly connected with the motor. The motor shall adopt B5 installation structure, and its protection grade shall be IP54, while insulation class F and temperature rise B. The motor bearing shall be self-lubricating ball bearing. The power reserve coefficient of the motor shall be per 110% so as to improve the safety in using the motor. Fan cylinder internal should be equipped with guide vane to improve aerodynamic performance and static pressure efficiency, smoother air flow is required, and the blades of the guide vane shall be of 3d curved surface in compliance with flow field characteristics.
Junction box of motor: Since the motor is within the fan, the supplier shall provide junction boxes to lead the wire out of the fan, and correct types of junction boxes shall be selected according to the specific application, such as fire protection type, explosion-proof type and common type. 


Fan surface shall be polished and cleaned up to remove particulates, welding slag, burrs, sharp edge, iron, oil, then epoxy coating [options: colour changes are available], fan surface shall be free of sags, wrinkle, blisters, exposed metal or peeling after coating. It shall be no corrosion and rust at least 10 years in allowable working condition. 

Explosion-proof Structure (Only for explosion-proof type)
