Greatech Machinery Industrial Co.

What Greatech Machinery Industrial Co. does

Greatech Machinery Industrial Co., Ltd. (廣勝工業有限公司) is a Taiwan-based, privately held manufacturer of Roots blowers, vacuum pumps, and related pneumatic equipment, headquartered at No. 701, Jhongshan North Rd., YongKang District, Tainan City. The company has operated in the Roots blower and vacuum pump manufacturing industry for over 30 years and organizes its product portfolio into nine lines: SdB (circulating air-cooling, vertical, direct-drive), G Model (belt-driven tri-lobe, 14 sizes from G25 to G400), Water Cooling series (G50-G400), Oil Cooled series (G50-G300), GR Model (vertical, belt-free direct drive, GR80-GR300), Vacuum Pump series (G50V-G300V), Stainless Steel Blowers (SS304/SS316), Diffusers/Porous Tube Diffusers, and Acoustic Enclosures. The underlying technology is positive displacement with a tri-lobe impeller design, offered in air flows from 0.1 to 300 m3/min and pressures from 0 to 20,000 mmAq (0 to 2 kgf/cm²). Differentiators claimed include energy efficiency from the tri-lobe geometry, low noise and low vibration suitable for installation in noise-sensitive facilities, oil-free output for clean applications, and SS304/SS316 construction for corrosive and biogas service.

The business model is direct factory sales from the Taiwan headquarters to industrial buyers worldwide, with no intermediary distributors or resellers. Pricing is non-public and quote-based: customers submit technical specifications (motor Hz/voltage/phase/poles, air capacity, inlet/outlet pressure, application) through the company's website inquiry form. The company maintains a multilingual website (English, Traditional Chinese, Simplified Chinese), downloadable catalogs (G Type, SdB Type, GM Type) gated by Google Forms lead capture, Facebook and YouTube channels, and participates in international trade shows including the Taiwan International Fisheries and Seafood Show, Kaohsiung Industrial Automation Exhibition, Aquaculture Taiwan Expo, and the International Exhibition of Agriculture, Animal Husbandry and Livestock. End markets include industrial manufacturing (pneumatic conveying, powder and grain transport), wastewater and aquaculture aeration, semiconductor and chemical processing, hospitals/hotels/schools, and biogas applications. ISO 9001 (valid 2025-08 to 2028-08) and CE (valid 2025-10 to 2030-10) certifications support cross-border commercial activity. Geographic reach extends across 100+ declared countries spanning North America, South America, Europe, Middle East, Africa, Asia-Pacific, and Oceania, though actual shipment density versus inquiry-based footprint cannot be verified from public sources.
