Technical Information

1. Quality Standards

The fan shall be tested and certified in accordance with AMCA Standard 210 & 300, TUV EN 12101-3 for smoke application. AMCA Seal for (Efficiency Sound, Air Performance and Fan energy index FEI) shall be tagged on each fan before leaving the factory as a standard seal, for other seals shall be tagged on the fan according to application and customer needs.

The manufacturer shall obtain Production License for National Industrial Products and be certified by ISO 9001, ISO 14001, ISO 45001.

1. Fan Type

It shall be vane-axial fan with airfoil blades. The fan shall be direct driven and in a cylindrical structure. Behind the impeller in the cylindrical body, there shall be guiding vanes for airflow straightening. The guiding vane shall have a three-dimensional curved surface in line with flow field characteristics for better air performance and static efficiency.

1. Surface Processing 

The surface of the fan shall be polished to remove any protuberances, welding spatters, burrs, sharp edges and scrap iron. Then it shall undergo the processes of oil removal, pickling, and applying putty before being finished with electrostatic epoxy coatings processed under high temperature for strong adhesion. The surface shall be a level one without sags, cracks, cockles or detachment to avoid corrosion over a long period of time.
