A Fan Plant in Fu'an Fujian Since 2007

Fujian Diamond Electrical and Mechanical Equipment Co., Ltd. designs, manufactures and distributes air movement equipment for large-volume buildings. The range is deliberately narrow: HVLS ceiling fans, HVLS floor and stand fans, wall exhaust fans, high-temperature axial fans for drying kilns, and container diesel generators. Everything else we leave to somebody else.

What the company actually does

We focus on manufacturing and selling HVLS fans and axial fans, including industrial ceiling fans, commercial ceiling fans, big movable fans and exhaust fans. Our products and systems let a building perform better, cut heating, cooling and mechanical operating costs, and give the people inside it a healthier environment. The axial fans use aluminium blades and an H-class insulation motor, which is what makes them resistant to high temperature while still delivering large air volume and high pressure at low noise.

Why a coordinated layout beats buying fans one at a time

A coordinated approach to air movement is kinder to a budget than the piecemeal approach commonly seen on site. With the correct mix of fans and precise positioning we can deliver air movement to parts of a building where there are no fans at all, because the moving air column spreads outward along the floor rather than staying under the fan.

Committed to adapt

Requirements change and adaptability matters. The range covers easy-to-install and portable products in a variety of sizes, air movement options, speeds and light options, plus accessories, so a plant that starts with two fans in one bay can extend the same system into the next bay years later.

Committed to teach

We share what we know rather than holding it back. Selecting a fan diameter, deciding between destratification and exhaust, and comparing an HVLS fan against evaporative cooling are all decisions a buyer should be able to make with the numbers in front of them. That is what the knowledge section of this site is for.

Production and Inspection

Twelve Stations on the Line

The production and inspection equipment on our line, photographed in the Fu'an plant.

Laser Cutting Machine in the Diamond plant at Fu’an Fujian
Laser Cutting Machine — Housing rings, mounting brackets and motor plates are cut from sheet here, which keeps the hole pattern consistent between batches.
Automatic CNC Spinning Machine in the Diamond plant at Fu’an Fujian
Automatic CNC Spinning Machine — Fan housings and bell mouths are spun rather than rolled and welded, so the inlet profile stays round and the airflow stays attached.
Welding Manipulator in the Diamond plant at Fu’an Fujian
Welding Manipulator — Housing and flange welds are run on a manipulator, which holds the same heat input along the full seam.
Automatic Welding Machine in the Diamond plant at Fu’an Fujian
Automatic Welding Machine — Repetitive frame and bracket joints are welded automatically to take operator variation out of the structural parts.
Housing Finishing Equipment in the Diamond plant at Fu’an Fujian
Housing Finishing Equipment — Weld dressing and edge finishing before paint, so the powder layer sits on a clean surface and does not lift in a humid kiln.
High-Pressure Spraying Line in the Diamond plant at Fu’an Fujian
High-Pressure Spraying Line — The automated spray line handles housing coating, which is where custom colour requests are scheduled.
Stator Withstand Voltage Test in the Diamond plant at Fu’an Fujian
Stator Withstand Voltage Test — Every stator is hipot tested. A winding fault found here costs a stator, the same fault found in a customer's drying kiln costs a shutdown.
Dynamic Balance of Wind Blade in the Diamond plant at Fu’an Fujian
Dynamic Balance of Wind Blade — Blades and impellers are dynamically balanced. Vibration is what destroys bearings on a fan that runs continuously.
Inspection Station One in the Diamond plant at Fu’an Fujian
Inspection Station One — Dimensional and electrical checks on finished assemblies before they move to packing.
Inspection Station Two in the Diamond plant at Fu’an Fujian
Inspection Station Two — Performance checks on the motor and control electronics under load.
Inspection Station Three in the Diamond plant at Fu’an Fujian
Inspection Station Three — Protection-class and sealing checks for fans destined for wet or dusty environments.
Inspection Station Four in the Diamond plant at Fu’an Fujian
Inspection Station Four — Final functional test with the controller fitted, run before the fan is crated.

Questions

Questions About the Company

The plant is at Tianban Industry Area No.168, Xibing, Fu'an, Fujian, China. Visits are welcome and we recommend them: an on-site inspection is the only way to compare the scale, the equipment and the process of one supplier against another. Message us on WhatsApp a week ahead so the line is running the products you want to see.

The company has focused on production since 2007. HVLS fans were introduced to the Chinese market around the same period, first through agency work for foreign brands and then through local manufacturing, which is the path this factory followed.

The CBF explosion-proof range carries ExdIIBT4 marking against GB3836.2 and IEC 60079 and is described as ATEX rated. The CRF diagonal grain drying fan holds Chinese utility model patent ZL201320208067.5. Copies of certificates and the patent document are issued on request; other certification claims are not made on this site because we will not publish what we cannot evidence.

Yes. Send the building length, width, clear height, roof structure type, the position of racking, cranes or partitions, and the grid voltage. We return a fan count, positions and an estimated coverage, and we will tell you when a smaller number of larger fans is the cheaper answer.

Both. Distributors and installers are supported with product data and layout support, and branding on the blades, housing and nameplate can follow your specification on production orders.
