Gaobeidian Gerui · General and process-air fan manufacture

What this manufacturer offers

Gaobeidian Gerui Environmental Protection Fan Factory, legally 高碑店市格瑞环保风机厂, is a Hebei lead for general and process-air fans. The original CRM export records establishment on 18 March 2008 and credit code 91130684679900215Q. The official homepage independently states a 2008 start, and the current website contact locality agrees with the CRM registered address: within the Xishuo building-materials premises east of Guangwei Avenue, Fangguan, Gaobeidian. The CRM annual-report and correspondence fields retain an older Zhuanghuo locality; they have not been rewritten to make the records look uniform.

The reviewed catalogue contains actual T35 and GD30K2 axial schedules, 4-72 centrifugal arrangements and a 9-19 high-pressure schedule. It is useful for preliminary duty enquiries, but also contains malformed model strings, blank size cells and tables filed under the wrong headings. Gerui describes fabrication, tooling and balancing capability; its present equipment and honour sections display no items. This profile therefore evaluates the disclosed products and source consistency without claiming a factory visit, an independently audited production rate or current certification.
