Item # EnviroAire 75 kW, GD EnviroAire - Oil-Free Variable Speed - Rotary Screw Compressors

Peace of Mind
Where contaminated compressed air can result in expensive product spoilage, you can rest assured that a Gardner Denver oil-free compressor will eliminate oil-carryover in the compressed air supply. In addition, the removal of oil from the compression process enables compressed air users to operate with maximum environmental efficiency.

A Diverse Range of Industries
Industries, both large and small, rely on Gardner Denver for a consistant supply of high quality clean compressed air, including automotive, aviation, petro-chemical, power generation, shipping and the utilities.
In situations where compressed air comes into direct contact with the products being manufactured: for example food and drink, pharmaceuticals, electronics and textiles, Gardner Denver compressors have been helping clients meet their quality and production objectives for many years.
Ongoing investment in the latest design and manufacturing tools, and rigorous implementation of ISO 9001 approved quality systems, ensure you take delivery of a reliable, high quality product.
Factory performance and functional testing guarantee that your compressor will operate and perform perfectly.
