Atlas Copco Rotary Screw Vacuum Technology
Atlas Copco has rapidly become one of the largest players in the vacuum industry. They have brought their expertise in low life-cycle cost and customer-friendly (low sound and space requirements) from rotary screw air compressors to the vacuum market. “We see industry centralizing their vacuum systems in industrial plants,” said Atlas Copco Vice President of Marketing Conrad Latham. “Plants are moving away from dozens of decentralized pumps to centralized systems with modern variable speed drives and electronic controllers able to optimize their energy costs and reduce maintenance costs.”
Targeting 400 mbar, the new GHS Series however looks and feels like a modern rotary screw air compressor. The standard Elektronikon controller, the sound attenuated enclosure complement modulating valves helping with the retention of oil mist able to improve performance. Vacuum industry veterans on the Atlas Copco vacuum team like Mark Taylor and Phil Berridge commented, “Vacuum pumps used to be owned by the operators. Today, the trend is moving aggressively to facilities people taking ownership. This is driving the adoption of our new full-feature rotary screw technology.” Visit www.atlascopco.us.

Aerzen Introduces New Models
Aerzen has always been a very interesting company to me as they fill an interesting pressure niche. The Company introduced the new E-Compressor design of the Delta Screw product family. “E” stands for energy efficient as they offer energy savings of up to 6% over the prior design. The new series of E-Compressors consists of four model sizes covering a flow range of 900 to 6.700 m3/h and drive capacities of 55 kW to 630 kW. These single-stage, oil-free screw compressors are designed for 2.0 bar (29.4 psi) and 3.0 bar (44.1 psi) operating pressures.
The company also introduced their largest model yet (150 m3/min) of their Delta Hybrid rotary lobe compressor for overpressures up to 1500 mbar and vacuum to -700 mbar. This new technology, combining their positive displacement blower and rotary screw air compressor knowledge, has had an impact on the market. This new pressure range can be applied to suction conveyance application in the food and plastic granulate industries. Aerzen USA is located outside Philadelphia in Coatesville, PA. They have long been experts in pneumatic conveying – both pressure and suction conveyance. The company also has significant business units focused on the wastewater aeration and biogas markets. They are currently building a plant in Shanghai, China. Visit www.aerzenusa.com.

Pneumofore Since 1923
It was a real pleasure to meet the Swiss/Italian team of Pneumofore. CEO Daniel Hilfiker said, “Pneumofore today distinguishes itself by designing and manufacturing the world’s largest and most robust air-cooled rotary vane vacuum pumps.” The UV Series rotary vane vacuum pumps offer nominal capacity flows from 250 to 2700 m3/h at an operating pressure range from 450 to 0.5 mbar(a). The units run at 1460 rpm and offer single-stage intake volumes of 250 to 3,240 m3/h and 99.95% maximum vacuum degree reached with 0.5 mbar(a) residual pressure.
The Company’s A Series features hard aluminum alloy vanes for heavy duty 24/7 operation. The pressure range is from 2.5 to 10 bar with a capacity range from 67 to 2,037 m3/h. I was impressed by their focus on lifecycle costs. Hilfiker continued, “Pneumofore designs are used where durability is critical. Our engineering focuses on reducing maintenance costs and enduring the most difficult working conditions.”
We had interesting discussions as they attempted bravely to educate me on severe applications “standard” machines struggle to handle. “Our A HC Series is an air-cooled unit designed for hot climates with ambient temperatures up to 55 C (131 F). We are regularly called in to solve applications after more than one other design/brand has been attempted,” said Hilfiker. Interestingly, their U.S. market manager, Amin Kardosh, was just preparing to visit New Jersey and California to review the successful installation of their machines in demanding applications where others had failed.

Pfeiffer Vacuum Celebrates 125 Years
Pfeiffer Vacuum has been setting standards in vacuum technology for 125 years now. It was in 1890 that Arthur Pfeiffer founded the company in Wetzlar, Germany. In the years that followed, Pfeiffer Vacuum played a decisive role in shaping vacuum technology. The major milestone was the invention of the turbopump in 1958. It revolutionized the industry, since it was the first pump ever to generate oil-free vacuum – the key at the time for opening up extensive new applications.
As modern technologies progressed, Pfeiffer Vacuum‘s operations became increasingly broad-based, and the company established itself with its acquisition of adixen Vacuum Products and Trinos Vakuum-Systeme in 2010 as a one-stop supplier of complete vacuum solutions. The company’s portfolio today spans not only vacuum pumps and leak detectors but also measurement instruments and analysis equipment, and encompasses both complete systems and wide-ranging service options as well as consultation services.
Launched right on time for the anniversary year, Pfeiffer Vacuum presented at the Hannover Fair, a range of new products together with a new online experience showcasing its vacuum solutions www.pfeiffer-vacuum-solutions.com.
Pfeiffer Vacuum products are used in manufacturing processes to make a wide range of essential everyday products. Vacuum technology is present everywhere in our daily lives – a fact which often goes unnoticed by consumers.
Eyeglass lenses are just one example of objects that are coated in a vacuum. Indispensable tools for this process are backing pumps, turbopumps, leak detectors, and measurement instruments made by Pfeiffer Vacuum. The coated lenses are protected from scratches and dirt and provide clear vision and antireflection properties. Pfeiffer Vacuum solutions play a crucial part in food production, too. Without them, vacuum freeze-dried products such as instant coffee or powdered milk could not be manufactured. Vacuum coated chip packets and other food packaging would not be possible – and food would have a much shorter shelf life.
Smartphones, tablets and PCs would not work without memory chips produced under vacuum conditions in a cleanroom. Cars would not have safe airbags, rims, tanks, or air conditioning hoses, since all of these objects are tested for leaks using vacuum systems and helium leak detectors. To continue to optimize those essential comforts and little extras that make our everyday life so convenient, Pfeiffer Vacuum is full of new ideas for new products and developments aimed at making a better future. Pfeiffer Vacuum, Inc. is located in New Hampshire. Visit www.pfeiffer-vacuum.com.
