Oil-free screw air compressors compress air through two screw rotors and then remove moisture from the compressed air through a water-gas separator. At the same time, because there is no oil injection for cooling, the compressed air is usually cooled, equipped with pre-coolers, intercoolers, and aftercoolers, to meet the requirements of the outlet temperature. High-performance shaft seals on the rotor shaft prevent lubricating oil from leaking into the compressed air, achieving oil-free operation. UNITED oil-free variable speed screw air compressors can change the power frequency, adjust the load, and reduce power consumption. The frequency converter is at its core, changing the motor's operating speed through the conversion of industrial frequency.

UNITED OSD oil-free variable speed screw air compressors can change the power frequency, adjust the load, and reduce power consumption. The frequency converter, with the inverter as its core, changes the motor's operating speed through the conversion of industrial frequency.
The stationary scroll and orbiting scroll of an oil-free scroll air compressor move in a small radius plane at specific phases. The orbiting scroll engages with the stationary scroll to form several enclosed crescent-shaped compression chambers. Air drawn into the working chamber is gradually compressed by subsequent crescent-shaped compression chambers and then discharged from the outlet at the center of the stationary scroll. The oil-free compressed air produced by oil-free scroll compressors is widely used in food, medicine, electronics, printing, chemical, precision spraying and other fields.
UNITED OSD's new generation UDBS series oil-free screw blowers are manufactured using advanced screw profile technology. By operating on the principle of internal compression, the compression efficiency is significantly improved. Compared to the external compression of traditional Roots blowers, its actual energy-saving rate is up to 35%. As a highly energy-efficient positive displacement blower, it is widely used in industries requiring energy saving, low noise, and efficiency, such as wastewater aeration, air-water backwashing, oxidative desulfurization, fluidization/homogenization technology, pneumatic conveying, and printing. It also functions as a pressure fan for drying, dust removal, fermentation, evaporative distillation, and pneumatic conveying.
