High quality manufacturing and assembling
Made in Germany
Quality assurance ?bench test of every air end
before leaving our factory
Easy application selection with our new
ROTORCOMP SIZING AIR software
Highest flexibility for your package design
Suitable for all types of drive driving motors
Drive options: Belt drive, direct drive, internal gear drive
Base and face-flange mounting
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
All of our LGFD air screw compressors have special Drives and electrics system that is almost loss-free power transmission guarantees reliable, high-performance compressor operation. The regular maintenance requirement is reduced to lubrication of the motor.
All the electronic components are brand products of leading manufacturers. rives and electrics. The Air end of our LGFD rotary screw compressor-made in Germany. The centrepiece of the compressor is the air end, which is constructed and manufactured with the most modern production methods in Germany. The optimal air end for your compressor can be used on a modulating basis. In frequency-controlled units, where the operating pressure changes, adjustments can also be made on the frequency controller to optimally adjust the speed of the compressor to the compressor performance.
