Company Profile
Shanghai Granklin (Group) Co., Ltd. is located in the Baoshan Robot Industrial Park in Shanghai, covering 60 mu, and focuses on the R&D, design, manufacturing, and sales of oil-free screw compressors while continuously improving its product development, manufacturing, and service systems.
Supported by its R&D capabilities, production equipment, and quality management system, the company continues to improve Granklin-branded water-lubricated oil-free screw compressor products.
The current product portfolio includes standard water-lubricated oil-free screw compressors, low-pressure oil-free screw compressors, medium-pressure oil-free screw compressors, energy-saving two-stage oil-free screw compressors, permanent-magnet variable-speed series, and specialty process gas compressors. Certifications, qualifications, and application scopes are subject to the company's currently valid certificates and corresponding product documentation.
technology leads the future!
Integrity, with Customers First Technology Leads the Future!
Industrial applications such as pharmaceuticals, electronics, chemicals, microbial fermentation, blow molding, pressure testing, and power plants have different requirements for compressed air pressure, cleanliness, and continuous supply. Granklin's current products cover low-pressure, standard-pressure, medium-pressure, variable-speed, and specialty process gas applications. Actual selection should be determined based on flow, pressure, air quality, cooling conditions, operating hours, and the air-treatment system.

Meshing & Water-Lubrication Structure
In a water-lubricated single-screw structure, the rotor, star-wheel meshing, and water medium work together for sealing, cooling, and lubrication. Air-end design must account for meshing accuracy, the low viscosity of water, material wear resistance, and long-term operating conditions.
-
Mechanical Sealing & Media Isolation
Mechanical seals help isolate the bearing lubrication area from the compressed-medium path. Actual air quality, seal life, and maintenance intervals should be determined from the specific product configuration, test results, operating load, and maintenance conditions rather than a single fixed service life or absolute claims.
-
Corrosion-Resistant Materials & Water Treatment
For water-lubricated systems, air-end materials, corrosion-protection design, and water-quality management directly affect equipment stability and maintenance intervals. For different media or corrosive operating conditions, material compatibility should be verified and appropriate water-treatment and monitoring solutions configured according to site water quality, temperature, and system design.
