Peak Performance

The Gardner Denver Apex series offers the performance and reliability that you demand, delivered by a simple and proven industrial design. With industrial grade components the Apex series is not a typical throw-away compressor! It is an investment in your organization’s future.

Instead of developing a package and then selecting an airend, we designed the airend and then built the package. The newly enhanced airend included in the Apex Series has improved efficiency by over its predecessor and increased bearing life over 50%.

Low Sound
With dBA levels as low as 67, the Apex Series can be installed next to the point-of-use. In addition to lower overall installation costs, the low sound level results in a safer work environment.

With a 27 x 31 x 43 footprint, the Apex Series has one of the smallest footprints in the industry.

Ease of Maintenance
The Apex Series has been designed so all routine maintenance can be accomplished in as little as 15 minutes, with no specialized tools needed!
