Fibreglass Belt-Drive Exhaust Fan

What the platform listing verifies

This fan is the product listed on Global Sources under the supplier name Foshan Daiho Equipment Co., Ltd. The listing describes a high-efficiency belt-drive nylon cone-shaped ventilation exhaust fan for agricultural machinery and poultry equipment. Its housing and discharge cone are described as durable and aerodynamic fibreglass, backed by a limited life-time warranty in the listing's wording. The blade is cast aluminium, described as high intensity and corrosion resistant, and the support is rugged manganese aluminium alloy, described as light weight and corrosion resistant.

Features, as listed on the platform page

• Fibreglass housing and discharge cone, aerodynamic shape
• Cast aluminium blade; stainless steel propeller and hardware
• Fan bearing with an oil hole, for regular lubrication to prolong useful time
• Enclosed motor base and automatic belt tensioner for lubricant
• Cast iron taper sleeve pulley, slideable and easy to adjust
• Imported V belt, described as showing little deformation and a long lifespan
• High-performance stainless steel propeller and hardware
• Permanent-Magnet (PMAC) motor with an individually-tuned integral drive
• Shutters available in aluminium or white PVC

Electrical options, as listed

Fan options include single or three phase inputs in either 50 Hz or 60 Hz at 200–240 V, 380–420 V, or 420–480 V, as listed. The listing adds a note to call for 50 Hz. That note is preserved here because it is a real ordering detail: a buyer on a 50 Hz supply should not assume the 60 Hz configuration, and should confirm the exact configuration in writing before payment.

Production features, as listed

The listing states that Daiho fibreglass fans feature high air performance, high strength, and corrosion resistance, with outstanding application in rigid working environments such as poultry farms and industries, and that all parts resist corrosive air from inside while enduring heat and sunshine from outside. It states that the company uses quality brand parts and advanced high-tech testing equipment to ensure every fan is strictly tested before leaving the factory. Those are the listing's statements; the public site attributes them to the listing and does not upgrade them into independent test results.

Where it fits, and what to confirm

This fan belongs in the same negative pressure family as the butterfly cone fan, but with a fibreglass body rather than galvanised steel. Fibreglass suits corrosive air — ammonia in livestock housing, humid coastal air, and chemical-laden workshop air — where steel needs more protection. The trade-off to ask about is repairability and spare parts: belt, bearing, pulley, and shutter availability over the life of the fan. Confirm the belt size, the bearing type, and whether shutters are included or optional, and confirm the price and terms in the inquiry reply rather than relying on any listing price, which is not carried onto this site.

A further ordering detail deserves attention, because it is easy to miss in a platform listing. The listing describes the fibreglass housing and discharge cone as backed by a limited life-time warranty, in the listing's own wording. Limited warranties vary widely in what they cover — housing, blade, motor, and belt are often covered differently — so a buyer should ask for the warranty terms in writing, broken down by component, before treating that phrase as a guarantee. The same discipline applies to the motor: the listing describes a Permanent-Magnet motor with an individually-tuned integral drive, which is a specific motor technology, not a generic claim about efficiency. Ask which drive settings are tuned to which fan size, and whether the drive is supplied as part of the fan or as a separate component, because that determines who is responsible if the drive and the fan do not match on site.
