Wordfik DVS series dry screw vacuum pump is a vacuum equipment innovatively developed and designed by our company. DVS adopts an integrated design, built-in vector intelligent control inverter, small footprint, low noise and low vibration. The rotor adopts a variable pitch design, which can save more than 30% of energy consumption.
There is no metal friction between the rotor and the rotor, and between the rotor and the pump body, no lubricating oil is required, and no high temperature will be generated during operation.
The DVS series has the advantages of ultra-high reliability, ultra-low operation and maintenance costs, clean and corrosion-resistant, efficient and intelligent, smart and convenient, silent and energy-saving, etc., and is widely used in precision instruments, medical, laboratory, semiconductor and industrial fields.
Features:
• Variable Pitch Energy-saving Technology
• Vector Intelligent Control Inverter
• Clean and No Oil
• No Metal Friction, Low Operating Temperature
• Low Noise and Low Vibration
