Ultimate efficiency and reduced noise through
High volumetric output due to
• Reduced internal leakage
• Thermally optimized oil injection system
• Improved suction port efficiency giving reduced
internal losses
Low power consumption due to
• Optimized torque characteristics and reduced
internal friction
• Improved outlet port with lower pressure losses
Reduced noise and low vibration due to
• Smooth rolling of the rotors with new
ROLLING PROFILE®
• Optimized outlet port
We design the new Oil separation system for our LGFD air screw compressor that Compressors up to 132 kW are equipped with external separators that can be changed in a simple spin-off/spin-on process. Larger units have an internal separator cartridge. Due to the excellent separation efficiency of the system as a whole, the compressors can be used in the pressure range of 5.0 to 15.0 bar. Special pressures on request.
And the Oil circuit of our LGFD rotary screw compressor is the amount of oil in the units is determined in such a way as to extend the oil change intervals (depending on ambient conditions).An oil level sensor is integrated as standard and is read by the controller. All the units in this series have a horizontal oil separation vessel in which the oil is separated from the compressed air highly efficiently at low speeds.
