Why Oil-Free?

Why Oil-Free?

N/A Contaminant Free… Risk Free

When you choose an oil-free EnviroAire series compressor from Gardner Denver™, you get a clean, reliable and efficient air supply that benefits both your business and your bottom line!

Air purity is critical for many applications where even the smallest drop of oil can cause product spoilage or damage production equipment. For this reason, the EnviroAire units from Gardner Denver™ contains absolutely no oil anywhere in the compressor and has been certified ISO 8573-1 Class Zero (2010) and silicone free, making it the ultimate choice with simply no risk of oil contamination.

Why Silicone-Free?

Why Silicone-Free?

N/A 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 compressors from GD offer the following benefits:
  • 100% silicone-free, guaranteed.
  • Specifically designed for use in pure-air critical applications such as the automotive industry.
  • Avoids contaminations and provides the highest air quality standards.
  • Independently tested and certified.

Gardner Denver™ EnviroAire Series

Gardner Denver™ EnviroAire Series

N/A A Superior Choice
The EnviroAire's unique water-injected, variable speed design achieves lower speeds combined with lower operating temperatures - resulting in high efficiency and reduced component wear.
  • Water injected into the compression element provides lubrication, sealing and cooling.
  • The superior cooling properties of water allow the compressor to operate at a low temperature providing near isothermal compression, low power consumption and class leading efficiency levels.
  • A reverse osmosis membrane cartridge filters the injection water entering the compressor; as a result the water is always maintained at a high purity level.

Peace of Mind

Peace of Mind

N/A Where contaminated compressed air can result in expensive product spoilage, you can rest assured that a Gardner Denver™ oil-less 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.

Balanced Bearing Loads

Balanced Bearing Loads

N/A The direct driven air-end offers the highest level of efficiency and reliability. With exceptionally low rotational speeds, the innovative design of the air-end compresses air on both sides of the rotor significantly reducing bearing loads and increasing efficiency.
Compression Loads are Balanced Resulting in Low Bearing Loads and High Reliability
  • Low bearing loads and low speeds mean sealed-for life bearings can be used, requiring no oil lubrication.

Designed for Water Injection

Designed for Water Injection

N/A Gardner Denver's EnviroAire Series compressors feature durable, twin gate rotors and single stage direct driven compression element
  • Bronze single 6 flute main rotor.
  • Low temperature rise eliminates the need for a final air cooler, which reduces pressure losses.
  • No metal to metal mating parts and low pulsation levels ensure low vibration and noise levels.
  • Carbon fiber composite 11-tooth gate rotors deliver 12 pulses of air per revolution compared with 6 pulses for a convention screw.
  • Sealed grease-lubricated main rotor bearings and water-lubricated gate rotor bearings extend rotor and bearing life.

Robust Design (High Efficiency Water Purification System)

Robust Design (High Efficiency Water Purification System)

N/A Reverse Osmosis (RO) membrane filtration system provides high quality water and reduces water requirements and operation costs
  • Ensures reliable and trouble free operation.
  • Injection water is drained to low level point by opening water drain valve and refilled with purified water from the tank.
  • Connects to potable water supply with pressure between 32 & 87 psig.
  • Water consumption is 4 - 10 gallons per day from potable water inlet supply.

Designing The Right System

Designing The Right System Information

N/A Let Gardner Denver™ Take Control

Gardner Denver™'s extensive distributor network is highly trained in the best practices associated with developing a reliable and efficient compressed air system.
One-stop shopping with your Gardner Denver™ distributor assures that all components of your system are compatible and backed by on-going customer support.

Compressors

N/A The heart of the compressed air system is the air compressor. The type, size and number of compressors depend on the needs of the application. However, all compressors have the same general function: use energy to compress atmospheric air that can then be used to power processes and equipment.

Piping

N/A Properly sized, designed and installed piping is critical to system performance. Piping should be designed for minimum pressure drop at maximum flow conditions. Gardner Denver™ features the Quick-Lock and Big-Lock lines of compressed air tubing. In addition to corrosion-resistant aluminum piping, these lines also feature nickel-plated brass fittings that come with a 10 year leak-free guarantee.

Storage

N/A Compressed air system storage is important to the overall performance of the compressed air system. Storage should take into account normal operating conditions and any large demand events. Air audits are a critical tool for the proper sizing of your system storage.

Filtration and Separation

N/A Filters are used to improve the quality of compressed air in your system. Filters are used to remove solid particulate, liquid water aerosols and vapors. Sizing and design of filters are important to system performance and longevity of downstream equipment and processes.

Air Dryers

N/A Air dryers are used to improve the quality of air in the system. The quality of air required is typically dependent on the down-stream processes and equipment.
Refrigerated air dryers remove moisture from the system by cooling the compressed air. Condensate forms as the air is cooled and the moisture is removed from the system.
Desiccant air dryers remove moisture from the air via the absorption process. Typically, a media is used to absorb moisture in compressed air.

Condensate Management

N/A One by-product of the air compression process is condensation. Often the water from a compressed air system will contain oil and other contaminates. The condensate management system will aid in separating the water from the other contaminates so water may be discharged down the drain while the contaminates are dealt with appropriately.

Flow Control

N/A Flow control valves provide physical separation of the supply and demand portions of the system. Distribution pressure is held tightly at target, regardless of compressor control band, thus eliminating excess waste in leakage and artificial demand. The flow control also manages the release of potential energy in receivers to enhance system stability.

Drains

N/A Drains are used to remove liquids from filters, dryers, receivers, piping and compressors. Liquid removal is important to system performance as well as downstream equipment and processes.

Point-of-Use Equipment

N/A Point-of-use solutions are available for special processes and downstream equipment that have unique requirements. These include compressors, dryers, filters, drains and regulators.

System Controllers and Sequencers

N/A For more complex, multi-compressor systems, system controllers and sequencers may be desirable. In addition to giving the user the ability to link multiple machines, system controllers may also add data logging capabilities, remote monitoring and logic to optimize the compressed air system. Sequencers bring machines on and off line to most efficiently match compressed air supply to the demand of the process.

Remote Monitoring

N/A Remote monitoring systems allow a machine to be observed from a remote location by the air compressor owner, the distributor or even the factory. By providing system performance data to the observer, a remote monitoring system ensures that the efficiency and lifespan of the compressed air system is maximized.

Keeping the System Healthy

N/A Just as vital as setting up the correct compressed air system is keeping that investment well maintained. By using Gardner Denver™ approved filters and accessories you can make sure the health of your system is maximized.
