Air purity is critical for many applications where even the smallest drop of oil can cause product spoilage or damage equipment. Depending on the application, one specific compressed air technology might provide advantages over another technology. Gardner Denver gives you the flexibility of several different oil-free compressor technologies to match your requirements: rotary screw, centrifugal, scroll and reciprocating.
Unlike oil lubricated compressors, oil-free air compressors have no oil present in the compression chamber. Oil-less air compressors contain no oil in the entire system, therefore, cancelling out any risk of oil contaminating the air. Each highly engineered product results in pure, quality compressed air.
Oil-lubricated air compressors use oil in the compression stage for sealing, lubrication and cooling. During operation, lubricating oil can be carried over into the compressed air system. A thorough understanding of compressed air quality and testing standards is therefore indispensable when designing your system to achieve the purity levels your application requires. Which standards you should apply will depend on the specific contaminants you aim to remove and the purification equipment you will rely on to do so.
The International Organization for Standardization (ISO) sets these standards and the ISO quality classes of air will help you determine whether or not you need an oil-free compressor. If your air quality requirements and oil carryover concerns dictate oil-free, the investment in an oil-free or oil-less air compressor will deliver the product quality that is demanded and valuable peace-of-mind. When evaluating oil-free air compressors, you will be presented with options such as single-stage, two-stage, water-injected single-stage, scroll and centrifugal technology choices. These technologies do overlap in certain horsepower ranges, but typically only two to three will be available for a given horsepower or flow size. Determining the size of oil-free air compressor you need first will help in your decision process.
As always, reach out to your local, authorized Gardner Denver distributor for assistance in evaluating which oil-free or oil-less air compressor is best suited for your specific application.
More major global manufacturers are now in this segment with traditional technology offerings and new products demonstrating better performance and a host of other key features and benefits. If you are after expense savings and better profitability, you are more likely to achieve these objectives now than in the past given the new oil-free technologies and the products that have accompanied them.

Our oil-free air compressors help companies across the globe meet and exceed their quality and production goals. Specific oil-free applications include food and beverage, pharmaceutical, electronic, healthcare and power generation to name a few.
Our oil-free compressors are built to last, featuring robust designs and a simple construction, making them easier to maintain. We’ve also made them easy to operate, featuring a variety of control options that put you in charge of your air supply.
Ultima is a ground-breaking, revolutionary oil-free air compressor. The design of this compressor range from Gardner Denver utilizes low pressure and high pressure dry screw airends. Each airend is individually driven by a variable speed, permanent magnet synchronous motor. This offers exceptional levels of efficiency versus traditional oil-free technology.
The unique design of the Ultima has allowed us to combine ultimate performance and efficiency. Because the highest cost in the lifecycle of any compressor is the energy to run it, the unique design of Ultima has allowed us to combine the ultimate performance with the ultimate efficiency. Furthermore, the Ultima provides a footprint 37% smaller than a conventional two-stage oil-free air compressor.
Also, to ensure optimal performance, the Ultima comes standard with iConn remote data analytics.
