What SHANGHAI GREELOY INDUSTRY CO., LTD does

Shanghai Greeloy Industry Co., Ltd (上海硅莱实业有限公司) is a Shanghai-based Chinese manufacturer and exporter specializing in silent, oil-free compressed air and vacuum equipment. Founded around 2001 and headquartered at the Qingpu Industrial Park in Shanghai, the company designs and produces a product portfolio spanning laboratory air compressors, standard silent oil-free compressors, large-displacement models, mini portable units, oil-free scroll compressors rated from 5.5 kW to 55 kW, and piston-type oil-free vacuum pumps. It also sells complementary gas drying and purification equipment — refrigerated, adsorption twin-tower, and heatless dryers — plus multi-grade gas filters, positioning it to deliver integrated clean-air source solutions rather than standalone components.

Greeloy's underlying technology centers on oil-free compression architectures, primarily self-developed piston-type and scroll-type mechanisms that combine in-house design with imported components. Its silent oil-free vacuum pumps feature dual safety protection (temperature control and electrical overload), built-in pre-filters, vacuum degree capability of -60 to -90 kPa, and noise levels at or below 55–60 dB. The GA-S series scroll compressors deliver 600 L/min to 6 m³/min at 8 Bar with intelligent control. The drying line uses cooling condensation, active alumina or molecular sieve adsorption, and PLC-controlled heatless regeneration, achieving pressure dew points as low as -40°C and filtration precision down to 0.001 μm. Products are described as self-developed with continuous technology innovation.

The revenue model is primarily one-time hardware sales of compressors and drying equipment, supplemented by recurring service revenue through a standard one-year warranty, post-warranty component-cost repairs, and free lifetime technical consultation. Pricing is quote-based and not publicly disclosed. Go-to-market is sales-led: direct factory and phone-based sales (hotlines 021-60719236 and 400-021-9236), an authorized domestic distributor program with active enforcement against unauthorized resellers, and direct export to international markets via a bilingual Chinese/English website. Named customer segments include the Chinese Academy of Sciences and its branches, major Chinese universities, well-known domestic and foreign laboratory equipment manufacturers, and world-famous electronics factories, serving end-applications in laboratory instrumentation, semiconductor manufacturing, optical coating, medical devices, pharmaceutical manufacturing, and food processing. The company operates from a single Shanghai manufacturing site with a stated production capacity exceeding 370 units per day.
