On July 16 2019, Bonaisi sales specialists and after‑sales engineers travelled to Shanghai Jiukai Wire and Cable Co., Ltd. and completed on‑site installation and commissioning for its 75 kW permanent‑magnet variable‑speed air compressor. This equipment delivery serves as fresh proof of Bonaisi’s product strength and marks Shanghai Jiukai Wire and Cable Company’s recognition for our brand. Bonaisi expresses sincere gratitude toward the client and is confident that the machine will deliver tangible economic benefits to its manufacturing operations. According to our on‑site sales representative, Shanghai Jiukai Wire and Cable Company proceeded with rigorous equipment selection during procurement. It requested quotations and comparisons from five well‑known air‑compressor manufacturers, including famous industry‑leading brands whose quoted prices were lower than Bonaisi. Against such competitive circumstances, the client opted for cooperation with Bonaisi. The outcome surprised our team and filled us with delight over the customer’s sensible choice.

When asked about reasons for selecting Bonaisi, the enterprise’s management offered a firm and practical reply: “When purchasing equipment, we do not fixate on minor price gaps of several thousand yuan. We prioritise product quality, energy‑saving performance and comprehensive cost‑effectiveness. After multi‑party comparison and field inspections, Bonaisi permanent‑magnet variable‑speed air compressors satisfy our core requirements. Hence we chose Bonaisi without hesitation and look forward to long‑term collaboration.”

Bonaisi permanent‑magnet variable‑speed air compressors did not claim victory by accident. This 75‑kW model is fitted with a permanent‑magnet synchronous motor equipped with NdFeB rare‑earth permanent magnets and a fully‑enclosed framework. Motor efficiency exceeds 96 %, well above conventional motor benchmarks. Efficiency remains intact under low‑frequency operation, eliminating no‑load energy losses generated by the load‑unload cycles of traditional machinery. Meanwhile, the intelligent variable‑speed control system dynamically adjusts motor rotation speed according to real‑time air‑consumption requirements, supporting stepless adjustment from 30 %‑100 %. Under variable operating conditions, average energy‑saving rates range from 20 %‑40 %. The compressor drastically cuts electricity bills, improves operational stability and meets three core priorities: quality, energy conservation and cost‑performance.

This successful partnership with Shanghai Jiukai Wire and Cable Co., Ltd. vividly embodies Bonaisi’s brand philosophy of “Building reputation via quality and capturing the market with energy‑saving technology”. As a major wire‑and‑cable manufacturer, the company enforces strict standards on production‑equipment stability and energy‑saving capability. Its decision to purchase Bonaisi machines acknowledges both product quality and reliable after‑sales service. Our after‑sales engineers followed standardised workflows throughout installation and commissioning. They delivered detailed guidance on routine operation and maintenance, enabling factory‑site operators to master equipment quickly and unlock its full performance potential.

We would like to thank Shanghai Jiukai Wire and Cable Co., Ltd. again for its trust and support. Moving forward, Bonaisi will keep focusing on air‑compressor research, continuously optimise product performance and upgrade after‑sales services. Improved offerings will be provided to all clients, helping more manufacturers cut operational costs, boost productivity and adopt eco‑friendly production, as we advance toward mutually‑beneficial cooperation.
