PLUS SILICONE FREE Screw Compressors Water-injected Technology Rely on GD to provide the perfect fit COMPRESSORS

Why oil-free? Don’t compromise on quality… If 100% clean and oil-free compressed air is a requirement for your industry, you cannot compromise on quality. The EnviroAire from GD sets the standards for air purity. These water-injected screw compressors are available in water-cooled and air-cooled versions and are ISO 8573-1 CLASS 0 certified. Offering not only 100% pure oil-free air but also improved energy efficiency, these compressors are made to meet the precise needs of a diverse range of industries. The ISO 8573-1 compressed air standard was revised in 2001 to address the requirements...

Why silicone-free? Silicone contamination in compressed air systems will cause problems across a wide range of industries, not least of all the automotive industry where a high quality finish is essential. Blisters, cracking, craters and a loss of adhesion are all symptoms of silicone contamination and will result in costly product spoilage and re-working in addition to production downtime. The ISO 8573-1 CLASS 0 certified EnviroAire T compressors from GD offer the following benefits: • 00% silicone-free, guaranteed 1 • pecifically designed for use in pure-air critical S applications such...

EnviroAire 15-110 Series Advanced totally oil-free technology No Oil - No Risk You can rest assured that the GD EnviroAire series is 100% oil-free with absolutely no oil present in any part of the compressor – unlike conventional 2-stage compressors, which use oil-flooded gear boxes. Hard facts… GD EnviroAire Technology Conventional Oil-Free Technology No, 100% Oil-Free compressor system Compression Temperature Compression Elements …and even more • Single-stage, direct-driven drive maximises efficiency and minimises maintenance • ariable speed technology available to reduce V energy costs •...

Superior design in every detail… 100% oil-free Low operating temperatures and bearing loads enable maintenance free sealed bearings to be used, totally removing the need for lubricating oil in the compressor. 1oo% oil-free compression is therefore guaranteed and the maintenance and environmental costs associated with oil and oil filter changes are eradicated. IP55, totally encIosed fan cooled high efficiency motor Energy efficient compressors are a major contribution to reduced “Total Life” costs. A dvanced motor-air-end arrangement The high output single stage c0mpression element is direct...

Save even more energy with our unique compressed air management system The GD Connect 12 can intelligently control up to 12 fixed speed or variable speed compressors. • Intelligently selecting the right combination of compressors • Reducing energy consumption by tightening the network pressure to the smallest possible band • Keeping off load running to the absolute minimum Each 1 bar decrease potentially results in a 6% reduction in energy consumption and as much as 25% decrease in air leakage losses.

EnviroAire VS Series: Our compressor solution for varying air demand Typically, air demand in a plant varies widely throughout the day. In addition, fluctuations can occur from shift-toshift, weekday-to-weekend, and season-to-season. Pressure requirements can also change from machine-to-machine or from one application to another. You need someone to evaluate your unique, often complex requirements and recommend a tailored solution. The VS variable speed compressor - one smart solution Variable speed compressors can efficiently and reliably handle the varying air demand found in most plant...
