The double screw oil free blower uses a pair of meshing screw rotors to suck in air from the intake end, compressand discharge it to the discharge end during rotation. There is no lubricating oil in the compression chamber, the female and male rotors are driven by synchronous gears to run synchronously. The air delivery is from 3~200m³/min.
Compared with the roots blower, the air delivery fluctuation is smaller. Due to the volumetric compression, the efficiency of screw blower is much higher than that of the roots blower, and the noise of screw blower is much lower.

Advantages：

	Screw Air End: ■ Bearings adapt to changing loads and provide a high degree of flexibility and efficiency ■ Ensure the smooth operation of the production process		Air Filter ■ High quality and high filtering grade, high process reliability and high efficiency. ■ Long service life and extended maintenance interval
	Sound-proof Cover: ■ Noise is greatly reduced by sound insulation sponge and metal door. ■ Reduce the cost of sound insulation equipment in blower installtion room ■ Easy to provide service to blower by opening the door.		Oil Circuit System: ■ Advanced oil circuit system design integrates oil pump, oil cooler and filter ■ Low oil temperature and long service life of bearings and gears
	High Efficiency PM Motor: ■ Low speed and high torque ■ Higher motor energy efficiency equal to IE4 ■ Independent fan for heat dissipation to ensure the stability of the motor.		High Efficiency Frequency Inverter: ■ Equipped with frequency inverter for energy saving efficiency, no need extra installation, easy operation. ■ Stable running and energy saving.
	PLC Control: ■ Integrated blower control system ■ HDisplay the overall system performance status, actively prompt maintenance and service information, fault and safe shutdown alarm		Air Inlet and Discharge Silencer: ■ Air inlet and discharge ports are installed in fixed positions to facilitate pipe connection ■ All grilles are lined to reduce noise ■ Independent cooling air flow to avoid recirculation
