Oil-Free Screw Blowers

Oil-free screw blowers are designed and manufactured using oil-free screw compressor technology experience, making oil-free screw blowers with high efficiency, low noise and 100% oil-free, and inefficient roots blowers will be phased out. Geso is a global manufacturer and supplier of screw air compressors. We are engaged in air separation system equipment for many years, and are committed to the research and production of air compressor systems. We can customize non-standard products and have a good price advantage. Our products cover the whole world. We look forward to being your long-term partner.

Energy Efficient Compressor Element

Adoption of Geso high-efficiency type profile creates high-efficiency and energy-saving

compressor element, and advanced coating technology improves the volumetric efficiency while effectively protecting the rotor.

Spiral seal assembly ensures oil-free air to reach higher levels Unique lubrication and oil drainage channels allow bearings and gears to be well lubricated and cooled, while enhancing the fficiency of the compressor element.

Frequency conversion control leads to a significant reduction in energy consumption

Energy consumption accounts for more than 80% of the life cycle cost of compressors and blowers. The actual air demand of most users is variable, and in almost any environment where air demand fluctuates with different factors (daily weekly or even monthly), inverter technology not only means energy savings, but also protects the environment.

Up to 35% energy savings

Permanent magnet motor drive

■ High efficiency: The excitation system loss is canceled, which improves the efficiency by 5-12%. High power factor, large torque-to-inertia ratio, reduced stator current and stator resistance loss, and measurable rotor parameters and good control performance. No matter light load or heavy

load, it always maintains high efficiency. Geso adopts permanent magnet motor with national class 1 energy efficiency standard.

■ Not full load, still high efficiency: Permanent magnet motor energy efficiency in full load operation than the conventional asynchronous motor is generally higher than 9%, with the speed down, its energy efficiency basically remains unchanged, while asynchronous motor speed with the reduction of its energy efficiency will be greatly reduced, or even reduced to less than 50%.

■ Stability: Synchronous motors respond quickly and excel in exhaust responsiveness.
