Parts

Quality

Each and every part that goes into a Gardner Denver compressed air system is tested and approved by our world-class engineering team. Pirate parts do not meet OEM specifications and often create costly operational problems that the provider has no capability to resolve.

Efficiency & Longevity

Energy consumption makes up about 86% of the cost of purchasing and running an air compressor for the initial 5 years. Using the right parts and getting them replaced at the right time prevents energy waste in producing the amount of compressed air needed by your operation. Dirty and inferior filters tend to increase the pressure drop, and energy across your compressed air system.

In addition to efficiency, inferior filters and separators are a huge factor in reducing the life expectancy of your air compressor. Inferior filters and separators allow more contaminants into your air compressor. Once those contaminants reach the vital air compressor components, the result can be anything from polluted, shorter-life lubricant to a total airend replacement.
