Price difference between oilless air compressor and oilless air compressor

In the procurement of industrial equipment, the price difference between oil-free air compressors and oil-containing air compressors is mainly due to differences in technical design, operating costs and long-term benefits. As a representative of oil-free technology, Granklin water-lubricated screw air compressor’s pricing logic reflects the following core factors:

1. Technical complexity and material costs
Oil-free air compressors require special design to operate without lubrication. Granklin adopts a water-lubricated single screw and star wheel structure, replacing traditional lubricating oil with water, requiring core components to have higher corrosion resistance and precision. Such innovative technologies require more R & D resources and the selection of special alloy materials, resulting in higher initial procurement costs than conventional oil-bearing models.

2. Maintenance cost variance
Oiled air compressors need to regularly replace lubricating oil, clean oil systems, and deal with oil separation problems. Additional maintenance costs are easily incurred during long-term use. Because oil-free models have no oil system, they eliminate the need for oil filter replacement and oil circuit maintenance, significantly reducing maintenance frequency and consumables costs. Granklin models further simplify the maintenance process through water lubrication technology. From the perspective of the full life cycle, the comprehensive use cost is more advantageous.

3. Application scenarios and added value
In industries such as pharmaceuticals, food, and electronics that require extremely high air cleanliness, oil-free air compressors are a necessary choice. If oil-bearing models are used in such scenarios, additional oil-water separation equipment and regular testing of oil content will be required, which will increase the overall investment. Granklin’s oil-free air compressor directly outputs compressed air that meets clean standards, avoiding secondary treatment costs and providing more cost-effective solutions for highly demanding users.

4. Equipment life and stability
Oil-free technology reduces equipment wear and extends the service life of core components by eliminating problems such as lubricating oil aging and carbon deposition. Granklin’s water-lubricated structure combines cooling and sealing functions, and provides stable operating temperatures, further reducing failure rates. In long-term use, equipment stability advantages can reduce downtime losses and improve production efficiency.

summary
The initial purchase cost of oil-free air compressors is high, but its oil-free design, low maintenance requirements and high cleanliness output can significantly reduce the overall cost of use in specific industries. Through technological innovation, Granklin water-lubricated screw air compressors optimize full life cycle costs while ensuring air quality, providing efficient and economical options for users with strict requirements for compressed air quality.
