Technical Information

1. Quality Standards

The fan has designed according to AMCA design procedure, the products are produced within very control procedure following ISO 9001, ISO14001 and ISO 45001.

1. Coating

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 5 years in allowable working condition.

1. Fan Type

The fan shall be the axial flow fan with cylindrical structure. The drive type shall be direct-drive.

1. Motor Chamber with Cooling System

Motor shall be installed in a special motor chamber, which isolates the motor from the exhaust air stream to avoid the influence of high air temperature. This chamber shall have special air channel, suck in fresh air from outside of the fan to cool the motor.
