Boge extends range of oil free piston compressors (Oct 2010)

26 October, 2010

Two years ago Boge launched its K series oil-free air compressors. This range has now been extended. Using the pushrod principle, the K series eliminates the complicated cross head construction. The cylinder bore in which the special-compound-coated piston moves is made of a high-strength aluminium-silicon alloy. These sliding partners lead to friction and therefore loss-free generation of compressed air.

This principle lays the foundation for the economic generation of oil-free compressed air. The K 3 to K 8 with 2.2 to 5.5 kW drives have free air deliveries of 0.24 to 0.65 m3/min for 10 bar and 15 bar operation. The K 8 is also available in a 40 bar version. The company reports that many users, in particular within the pharmaceutical and food & drinks industries, have been looking for a low-cost compressor that generates high quality oil-free compressed air. The new K 15 extends the range and uses two opposing pushrod units. Using this 'four cylinder' system has made it possible to now generate up to 1.2 m3/min of oil-free compressed air.
The compact and competitively priced K 15 utilises the pushrod principle, integrating a high efficiency control that makes this possible. Additionally, the K series operates on a stop/start basis – controlled by either a pressure switch (as a standard) or with the with the Boge BASIC electronic controller, which is said to ensure the most efficient use of energy. Boge adds that low service costs are also assured due to the state-of-the-art design, meaning very little maintenance is required. The K series is available as a 10, 15 or 40 bar compressor with effective free air deliveries ranging from 244 – 1296 l/min, motor range 2.2 to 11 kW.
