Jufeng · Guangdong history, current Wuxi production
The current manufacturer material identifies Jiangsu Jufeng Machinery Manufacturing Co., Ltd. (江苏巨风机械制造有限公司), in Huishan, Wuxi. The manufacturing history connects the earlier Guangdong/Panyu operation with present Jiangsu production.
The former brand site directs visitors to the current Jufeng sites and publishes a relocation/reorganization statement. Historical issuer disclosure separately records the Guangdong–Jiangsu manufacturing relationship.
- 2014 · component business
- Issuer disclosure records Guangdong Jufeng's acquisition of Suzhou Ouneng, a screw-component supplier.
- 2017 · Jiangsu company
- The same disclosure records Jiangsu Jufeng as a subsidiary and subsequent concentration of Ouneng's production operations there.
- Current offer
- Agree the exact legal seller, invoicing, manufacturing location and warranty responsibility. Manufacturing history does not make legal entities interchangeable.
Three manufacturing workshops
Air ends, sheet metal, assembly and test
Air-end workshop
The company describes rotor grinding and coordinate measurement, with machining facilities. Agree the air-end model/revision and order-specific inspection/traceability records.
Sheet-metal workshop
Punching, laser cutting, bending and coating are described separately. Cabinet construction, access and cooling-air path belong in the offered drawing.
Assembly and test
Assembly and test stations support completed units. Agree configuration, leak/performance checks and the records delivered with the machine.
Industrial two-stage screw
Separate compression stages, drive and control
The current product description identifies oil-injected, direct-drive equipment with PLC control and air/water cooling options. Choose the actual offered cooling and control arrangement.
- Two-stage compression describes the compression arrangement.
- Direct drive describes transmission between driver and air end.
- Variable-speed or fixed-speed control describes how the offered unit follows demand.
None of these terms supplies the exact pressure-flow-input rating. Request current model/revision and delivery plus complete-package input at the same duty and reference conditions.

Questions before selecting Jufeng equipment
Why does this Guangdong-history page describe Wuxi production?
The former brand site points to current Jufeng sites, which identify Jiangsu Jufeng in Huishan, Wuxi. Historical disclosure records the manufacturing relationship. Match the exact present seller and warranty entity in the offer.
Does two-stage mean two variable-speed drives?
No. Compression stages, mechanical drive and control arrangement are separate specifications. Identify the complete offered model and configuration.
Is every ODF-10A a belt-driven machine?
The current range has similarly numbered belt, direct-drive and other routes. The reference here is the ODF-10A/0.8 belt fixed-speed page. Match its construction and current bill of materials.
Can the motor kW establish the energy cost?
Obtain complete-package input at the selected pressure, delivery and reference conditions, including part-load operation where relevant. Add treatment and distribution losses for the installed system.
