KOMPRESSOREN is set­ting a tech­no­log­i­cal mile­stone in the screw com­pres­sor sec­tor, says the com­pany. Fol­low­ing a re­design, the com­pressed air sys­tem is not only ex­tremely ef­fi­cient, but also whis­perquiet at 69 dB(A). This also makes it suit­able for en­vi­ron­ments that are sen­si­tive to noise. The en­closed di­rect drive pro­vides for low­main­te­nance con­tin­u­ous oper­a­tion, even with high dust vol­umes. The con­trol sys­tem, fo­cus con­trol 2.0, sup­ports in­ter­con­nected oper­a­tion with up to four units with­out the use of ad­di­tional higher-level con­trol.

To cater for grow­ing de­mands from cus­tomers for com­pressed air sys­tems with min­i­mum power con­sump­tion in the per­for­mance range from 110 to 160 kW, the com­pany says it has turned the de­sign prin­ci­ple of the oil-lu­bri­cated screw com­pres­sor on its head. It owes its gain in ef­fi­ciency to ef­fi­lence In­te­grateDrive, BOGE’s first airend to fea­ture in­te­grated gears. The large- scale de­sign of the com­pres­sor pro­vides high de­liv­ery rates with low power con­sump­tion. The level of en­ergy con­sumed by the S- 4 com­pres­sors thus falls by as much as eight per­cent. The in­te­grated gears are her­met­i­cally en­closed. The drive has op­ti­mum pro­tec­tion from high lev­els of dust in the am­bi­ent air, which oc­cur, for ex­am­ple, when flour is used in the food in­dus­try. The re­sult is a low­main­te­nance, ex­tremely long ser­vice life of over 35,000 op­er­at­ing hours, prom­ises BOGE.


A ma­chine unit iso­lated from vi­bra­tions – that’s the key to low noise. At 69 dB(A) the new gen­er­a­tion is 7 dB(A) qui­eter than the pre­vi­ous model. To achieve this, BOGE iso­lated the oil sep­a­ra­tor from the base frame and the sound­hood to pre­vent the trans­mis­sion of any vi­bra­tions. To ac­com­plish iso­la­tion, BOGE come up with what it says it a first – de­sign­ing a ver­ti­cal oil sep­a­ra­tor with a new pre-sep­a­ra­tion sys­tem. Other ben­e­fits are a low resid­ual oil con­tent in the


The fo­cus con­trol 2.0 con­trol sys­tem is de­signed to an­tic­i­pate op­er­at­ing states and au­to­mat­i­cally ad­justs to the tem­per­a­tures and pres­sure lev­els that oc­cur. En­tirely in line with In­dus­try 4.0, the new BOGE sys­tem makes it pos­si­ble to si­mul­ta­ne­ously mon­i­tor the op­er­at­ing states and main­te­nance intervals of up to four com­pres­sors. This not only sig­nif­i­cantly ex­tends ser­vice life, but al­lows the user to take full ad­van­tage of the po­ten­tial of­fered by the sys­tem. Thanks to these at­tributes S- 4 screw com­pres­sors are suit­able e.g. for three-shift oper­a­tion. When main­te­nance is re­quired, there is easy ac­cess to com­po­nents via the re­mov­able ser­vice doors on two sides of the screw com­pres­sor.

com­pressed air, min­i­mal pres­sure losses and a long ser­vice life for the sep­a­rat­ing el­e­ment. As the ma­chine is so quiet, it can also be used in en­vi­ron­ments that are sen­si­tive to noise, e.g. next to a work­sta­tion. No ad­di­tional sound in­su­la­tion is re­quired for the struc­ture.
