Granklin water-lubricated single-screw air compressors: an innovator in oil-free compression technology
grantklin water-lubricated single-screw air compressor adopts the compression structure of single screw meshing with star wheel, and water replaces traditional lubricating oil to realize rotor cooling and sealing. This design from the root of the oil pollution, for food processing, pharmaceutical, electronic manufacturing and other demanding air quality industries to provide a pure oil-free compressed air solution.
oil-free compression mechanism
through the precise meshing of the screw rotor and the star wheel, the traditional oil lubrication system is replaced by the lubricity and cooling of water. The water film forms a dynamic seal between the rotor, star wheel and casing, which not only prevents gas leakage, but also absorbs the heat generated during compression to ensure compression efficiency and equipment stability.
Meshing Design of Single Screw and Star Wheel
the single screw rotor and the star wheel pieces symmetrically arranged on both sides form a compression cavity. The symmetrical layout makes the axial force and the radial force cancel each other, the life of the rotor bearing is significantly improved, and the maintenance cost is reduced.
Advantages of water lubrication technology
food and Beverage Industry
in canning, bottle blowing, packaging and other links, oil-free compressed air directly contact the product to ensure food safety and hygiene standards. Water lubrication technology avoids oil residues and meets the industry's stringent requirements for air purity.
Pharmaceutical and Medical Industry
from raw material mixing to preparation filling, compressed air drives pneumatic valves, actuators and other equipment. Oil-free environment to prevent cross-contamination, ensure drug quality and patient safety.
Electronics and Semiconductor Manufacturing
in precision processes such as chip production and circuit board cleaning, oil-free compressed air avoids particulate pollution and ensures product yield. Water lubrication technology provides stable gas supply support to meet high cleanliness requirements.
Chemical and Textile Industry
when compressing flammable and explosive gases, the low temperature characteristics of water lubrication improve safety; when compressing corrosive gases, the stainless steel host material enhances corrosion resistance and broadens the scope of application of the equipment.
energy saving and consumption reduction
two-stage compression technology reduces compression ratio, reduces backflow leakage and improves energy efficiency. Under the same working conditions, the second-stage compression ratio saves about 20% of energy than the first-stage compression, reducing the operating cost of the enterprise.
intelligent control system
integrated constant pressure control, frequency conversion soft start, put an end to no-load and other functions, according to the gas demand automatically adjust the output, to avoid energy waste. The IoT module supports remote monitoring for preventive maintenance.
Safety and environmental protection
multiple protection systems (overpressure, overtemperature, motor overload, etc.) ensure safe operation. Water lubrication technology reduces lubricant consumption and carbon emissions, in line with green manufacturing trends.
granklin water lubricated single screw air compressor with oil-free compression technology as the core, through the innovative design of single screw and star wheel, to provide efficient, reliable, low maintenance compressed air solutions for industrial production.

Oil-free air compressor is widely used in many fields because it can provide high-quality, oil-free compressed air. The following are some of the main applications: Food industry: In food processing and packaging, oil-free air compressors are used to provide high quality
During the maintenance of the air compressor, in order to ensure its long-term and efficient operation, the following core components need to be replaced regularly: 1. Air filter function: filter dust, particles and other impurities in the inhaled air to prevent it from entering the compression chamber and protect Internal precision parts. Replacement
The main reasons that affect the electricity bill of the air compressor are as follows: The rated power of the air compressor: The rated power of the air compressor is one of the important factors that affect the electricity bill. The greater the rated power, the higher the power consumption per unit time, resulting in an increase in electricity charges. Because
The industries with a large amount of air compressor gas mainly include manufacturing, energy industry, chemical industry and so on. The following is a detailed analysis of these industries: 1. Manufacturing overview: The manufacturing industry is one of the industries with the largest demand for air compressors. In the production process, many manufacturing processes are
The screw air compressor itself is not classified as a container, but as a type of compressor. A container usually refers to a closed device used to store a gas, liquid or solid, such as a gas storage tank, a liquid storage tank, etc. Screw air compressor is a kind of screw rotation
In the electroplating industry, the specific demand for air compressors is mainly reflected in the following aspects: Compressed air: In the electroplating process, gas is required for operation. For example, soaking the metal substance in the electrolyte solution and introducing gas to control the reaction speed
Compressed air oil content standards vary by application and industry. The following are some common oil content standards for compressed air: Chinese Pharmacopoeia and GMP standards: require compressed air oil content ≤ 0.1 mg/m & sup3;. This standard is from the European Pharmacopoeia regulations.
Estimating the amount of compressed gas in one year needs to be calculated in combination with production equipment parameters, operating time, gas fluctuations and losses, which can be achieved by equipment gas consumption statistics, unit product gas consumption or empirical estimation. The following are specific steps and examples: 1
Medical oil-free air compressor is a special kind of gas compression equipment, which plays a vital role in the medical industry. Its main uses include the following aspects: 1. to provide dry, clean and stable air supply medical oil-free air compressor can output dry,
In the salt spray test, the oil content of compressed gas should be strictly controlled within 0.01 mg/m & sup3;. This standard is formulated according to ISO 8573-1 compressed air quality grade. The specific analysis is as follows: The core of 1. oil content control is based on international standards (ISO 8573-1) The standard
