Rotary vane compressors, oil-freeRotary vane compressors, oil-free

Simplicity of design with only one shaft and direct drive produces robust, long-lasting compressors with low maintenance and running costs. These compressors operate completely oil-free; the individual chambers are separated by long-life vanes. …

Already featuring integrated intake filters and control valves, these compressors can be fitted with other accessories without a problem. The blast-air cooler, which is also integrated, guarantees a very low blast air temperature. The compact cover ensures low noise and heat emission. Optional corrosion protection also makes these compressors suitable for extracting moist air.

The frequency inverter integrated in the VARIAIR UNIT significantly enhances the
performance data of rotary vane compressors. It matches compressor delivery exactly to customer requirements. Energy consumption is optimised and constant vacuum is guaranteed even where demand is subject to Variation or severe fluctuation. As no unnecessary blast air is generated, air discharge noise is kept to a minimum. “Gentle” compressor start-up reduces strain on mechanical components and reliably extends their useful life. Variable Output ranges minimise the number of different types required, thus also providing logistical advantages.

Series X: Becker Innovation with Top Warranty

Pneumatic technology of the Becker brand is worldwide a synonym for precisely dosed, smooth industrial processes in many industrial sectors. For application areas with high requirements, as they are common for example in the electronics industries, Becker offers the vacuum pump product line: the series X.

With this special development [suitable for the application], Becker extends its popular DT/KDT/DTLF product range by the models DX, KDX and DXLF.

Equipped with specially developed vanes, these oil-free rotary vane pumps distinguish themselves by high abrasion resistance and with that extremely long service lives. And since no dust develops where there is virtually no wear, the devices of the series X are perfectly suited for precision processes under clean room conditions.

The innovation branded by Becker is outstanding not only because of its 100 percent oil-free operation, excellent degree of efficiency and low power consumption. In the area of sensitive vacuum, series X also guarantees precise low-pulsation air conduction.

And to top that, Becker offers for the first time full warranty of at least 20,000 maintenance-free operating hours for this innovation – a guarantee for top technology with the following advantages:

• quick, clean, quiet
• oil-free
• vibration stable
• wear resistant
• energy saving
• long-life reliable

An additional reliability plus is the on-site service by Becker in case of need. Exchange installations and the downtimes associated with that are no longer an issue anymore.

Screw compressorsScrew compressors

 

Driven directly by an integrated frequency inverter, these pumps no longer require any drive transmission. The area in which the units work is 100% oil-free. The integrated speed governor optimises the use of energy by matching delivery to actual demand. This creates high efficiency levels and minimises energy consumption. Blast air remains pulsation-free all of the time. 

… Various accessories, such as intake filter, non-return valve, sound absorbers as well as the air delivery and discharge system, are integrated in the completely soundproof cover structure.

Advantages:

  • Direct-drive, no transmission required
  • 100% oil-free compression
  • 100% contact-free and non-wearing compression
  • Integrated frequency converter
  • Continuous output controlling
  • Small oil circuit for synchronisation transmission
  • Operating/ error messages shown in display
  • Compact unit, integrated accessories
  • Low noise levels
  • Lower maintenance requirements
  • Pulsation-free air vacuum and blast air
  • High degree of efficiency, low energy requirements
  • Modern design

IntroductionDescriptionTechnical

Side channel blowersSide channel blowers

Using “multi-stage” compression, side channel blowers generate low-pulsation blast air. Perfected impeller design with curved blades guarantees optimum efficiency. 

… Separation Of the compression chambers on both sides of the impeller permits single-stage, twin-flow as well as two-stage, single-flow operation with only one impeller. Intake filter and pressure safety valve can be integrated as an optional extra in the patented design of the sound absorbers. The sound absorbers can be varied in length, affording flexible adjustment to available installation space.

VARIAIR Logo

The frequency inverter integrated in the VARIAIR UNIT significantly enhances the performance data of side channel blowers. It matches compressor delivery exactly to customer requirements. The patented, sensorless control system that keeps pressure and volumetric flow constant ensures steady operation, even where differing suction-air rates or pressure levels are demanded. The speed range up to 6000 min-1 can be used to create compact, high-output units. The integrated electronic self-protection feature on the blowers saves the need for costly accessories, such as pressure safety valve or air discharge sound absorber. As no unnecessary blast air is generated, air discharge noise is kept to a minimum. Matching delivery exactly to the amount of air actually used guarantees optimised energy consumption.

VARIAIR Speed Flow Logo

Becker’s innovative VASF 50, 80, and 120 range of side channel blowers is particularly well suited to meeting requirements of the type placed on de-centralized vacuum or pressure generators in terms of system integration and operating efficieny by forward-pointing technoligies. Compact design, optimized aerodynamics, wide speed range with extremely low operating noise as well as “intelligent” drive electronics provide the basis for excellent performance and efficiency while keeping size and weight to a minimum. Modular design flexibility is the key to a single- or multi-stage version with AC or DC drive. A leap forward in technology ultimately expressed in a clearly defined, slim-line exterior.
