China is a large bearing making & applying country. Early in 2005, China have been the third largest bearing maker in the world. Bearings production & sales rapidly increased in mobile industry, agricultural industry, & machine tools.

Cost increasing in material, energy & labor, causing bearing enterprises double crashed by upper & lower markets. Air compressor running cost occupies a great proportion of running cost, thus, energy saving is very important.

Zhigao designed & made bearing manufacturing industry specialized screw air compressors -  two stage low pressure permanent magnetic variable frequency series. Zhigao industrial technology team R&D and tested the model for more than one year.

This model with the following features:

•   Large air production

•   Low energy consumption

•   High filtration precision

•   Large dust bearing capacity

•   Stable running

•   Convenient maintenance

At the same time, Zhigao optimized filtration system, oil separator system, & the match of rotor & electric motor. This model gained high level concern & recognition from clients. Our air compressors are greatly functional in ensuring production & lowering production cost.

Here is an example from Quzhou City Jianwo Jinggong Machinery Co., Ltd.

As a high & new tech enterprise supported by Qujiang government, Quzhou City Jianwo Jinggong Machinery Co., Ltd. produces 130,000,000 sets of bearings each year. All products are exported overseas, with annual income 250 million RMB. Through the communication of Zhigao & Jingwo equipment management personnel, Jingwo replaced old compressors with Zhigao two-stage low pressure energy saving 160SFT-5.5 screw air compressor. After 3-month of trial, they save 49KW.H of electricity each hour, totally saving 400,000 RMB annually.

Our continuously hard working leades to continuous energy saving. Zhigao actively prosecutes “energy saving” strategy, for more energy saving & more intelligent air compressors.
