All Our Compressors are equipped as Direct Drive
Drive 1:1 means that the Airend and motor are directly connected. This means that there are no transmission losses. BERG’s direct drive screw compressors deliver outstanding performance and make possible great savings in energy.
The drive motor and the air end in one-to-one drive series compressors are designed to operate at the same low speed. This enables the drive and compression units to be linked via a maintenance-free coupling which avoids the transmission losses with gear-driven units. our direct drive compressor reduces the number of components needed in comparison with gear drive, significantly increasing reliability and service life. Sound levels are also considerably lower. The airend in each KOMPBERG®️ BSD model is designed to specifically match air demand and ensures outstanding efficiency through the low-speed operation.
