Oil-injected screw air compressor
GL 55-90
The Smart Choice for Highly Reliable, Energy Efficient Applications
1.Advanced low-pressure screw mainframe
- Advanced asymmetric rotor profile design, large air volume, low energy consumption.
- Equal diameter design of rotor, close rigidity of yin and yang screws, better overall strength.
- Specially designed for low-pressure head, no over-compression, more energy-saving.
2.High efficiency motor
- High-efficiency IE3 motor, F-class insulation, B-class temperature rise, can ensure normal operation in harsh environments.
- SKF bearings ensure long motor life
- Equipped with phase sequence protector as standard, effectively preventing the motor from reversing.
3.Enlarged high-efficiency oil and gas separation system
- Reduced system pressure drop, effectively reducing energy consumption
- Oil content less than 2PPM, low oil consumption, lower maintenance costs, longer service life.
4.Pre-filter
- Air inlet filtration, effective protection of internal components, prolonging the life of the product
- Easy to disassemble and reuse
5.Heavy Duty Filter
- Removes 99.9% of coarse dust particles and protects compressor components.
- Extra large dust capacity for longer maintenance intervals.
6.Enlarged design of oil cooler and aftercooler
- Longer oil life due to lower rotor outlet temperature
- Elimination of thermal shock in the heat exchanger
- Elimination of thermal shocks in the heat exchanger Reduced system pressure drop and lower energy consumption
7.Elektronikon® touch screen controller - Built-in intelligent algorithms to optimise system pressure and reduce overall energy consumption
- Remote control, alarm outputs, maintenance scheduling and network diagnostics.
- Built-in Smartlink remote monitoring to keep track of the system status.
