Granklin Group's water-lubricated oil-free screw compressors, from design to manufacture, everywhere reflect our pursuit of energy saving, cleanliness and environmental protection.
From water lubrication to non-corrosive main engine shell, from stainless steel screw to silicon carbide sliding bearing that never rusts, from high-efficiency air filter to precision lubrication water filter, we ensure that XR parts are oil-free working design, we have always believed: professional casting quality, quality casts the future!
Structural Design of Grantklin Oil-free
because the screw in the process of rotating compression, the entire host lubrication, sealing, cooling are done by water, therefore, Granklin is the true sense of the oil-free compression.
Stainless steel host shell, stainless steel rotor, wear-resistant oil-free silicon carbide sliding bearings, the design life of the above components are up to 25 years. Thus, an absolutely oil-free compression volume produces absolutely oil-free compressed air.
Special Order
1. Special configuration, according to your site conditions, provide different voltage, paint color, explosion-proof grade design requirements;
2. Design customization for special environments, such as: low temperature, seaside corrosion, tropical, high temperature, dust, etc;
3. Provide special gas design: such as nitrogen compression, pressurized compression or higher design below 40bar;
4. Provide low pressure compression design below 1.5bar.
Granklin's new oil-free machine has been successfully launched after long-term testing to achieve stability and reliability. At present, it has been successfully used in steel, electronics, electric power, tobacco, textile, chemical, food and beverage, pharmaceutical and other industries covering the whole country. Grantklin believes: With our strong R & D, stable and excellent quality, competitive prices, and professional services, the new oil-free machine will be able to provide you and more companies with more excellent services......
Many customers in the purchase of oil-free screw air compressor when they do not know what makes a good oil-free screw air compressor, then let us understand the following, when users buy oil-free screw air compressor should mainly choose from the quality and function. Specific can be considered from the following aspects:
View detailsGood brands of air compressors are expensive, especially imported brands of air compressors, the price is very high, not every enterprise can afford. Brand added value in the imported air compressor reflected incisively and vividly, how to buy a good "air compressor brand", but also the right price is not easy.
View detailsAdvantages of dry oil-free air compressor products: 1. The motor adopts advanced design system to optimize the design to ensure that the compressor achieves high power, high efficiency, low energy consumption, high performance and high reliability. 2. The piston ring adopts new environmental protection material design, friction system
When it comes to air compressor equipment, we all know that the operation of air compressor equipment is required to use lubricating oil, lubricating oil mainly play a role in reducing wear and prolong the life of the air compressor, so oil-free air compressor equipment is the same?
Granklin water-lubricated air compressor has obtained a number of certifications to ensure that the gas provided is 100% oil-free, and the compressed air provided to users to meet the needs of users for high-quality air sources. If there is no local after-sales service center or entrusted distributor, you can directly contact the head office for warranty service.
It is obvious to all that the oil-free water lubrication air compressor is excellent. As a category of air compressor, the sales volume is increasing year by year. Users who do not understand its advantages can read this article. 1. The compressed gas of the non-oil-water lubricated air compressor is 100% oil-free, the whole structure of the air compressor is more reasonable, and the cost of maintenance consumables is less;
What are the daily contents of air compressor maintenance? What are the advantages of screw air compressor compared with piston air compressor? How does air compressor work? Air compressor is also called air compressor, which is a kind of equipment used to provide kinetic energy after compressing air. It is made of motor or wood
Choose Shanghai Granklin Group to purchase air compressors, whether it is price or service, do not lose imported screw air compressors. As for the price of an air compressor, the things involved are also in all aspects. Price is an important reference standard, but it is not the only weighing standard. We will definitely get good results under a telephone consultation.
View detailsNo oil is used in the compression chamber. Oil does not come into contact with compressed air, but does not remove the oil vapors contained in the atmosphere. This makes the compressed air still contain a small amount of oil impurities. After measurement, the oil content in the compressed air produced by the oil-free air compressor and the area where it is located
Oil-free air compressor theoretically no clearance volume, single capacity, ideal isothermal compression, due to the good thermal conductivity of water, lubricating water into the compression chamber, the temperature will drop to 45 ℃, close to the suction temperature. Oil-free: water to replace oil, lubrication, cooling, sealing, noise reduction of the four effects, to provide 100 oil-free air, no pollution, the discharge of water without special treatment, in line with environmental requirements.
