Product Features

The two-stage oil-free vacuum pump saves 40%-60% energy compared to the traditional water ring vacuum pump. It has high efficiency and low power consumption. It is more than 1.8 times more efficient than the water ring vacuum pump. It can quickly pay back the investment. The operating cost is low and the investment can be paid back in one year.

The oil-free two-stage vacuum pump adopts the energy-saving and environmental protection technology independently developed by DREAN, without any pollution.

Adhere to the high-end quality line, check the production process layer by layer, and operate the permanent magnet variable frequency intelligently and stably without worries, which helps global enterprises to develop rapidly.


Advantages of DMW-V series Permanent magnet variable frequency oil-free screw vacuum pump

  • Oil-free host

Adopt German SKF heavy-duty bearings and chisel wheels, stable operation;

Adopt imported high-end machining center to process the main machine, high precision, high efficiency;

Ultra-low maintenance costs, reducing operating costs;

Ultra-high temperature anti-corrosion coating design, long high temperature operation life.


  • High-efficiency permanent magnet motor (with independent fan)

Adopt high temperature stable permanent magnet steel (SH-40), high temperature resistance low risk of demagnetization;

soft start operation, stable running flow rate;

wider constant torque range and weak magnetic range, better control performance;

adopt extended core design, increase motor torque, good low frequency operation performance;

independent fan design, reduce low frequency running motor temperature rise;

independent motor bearing temperature control system to ensure motor no bearing damage.


  • Advantages of intelligent controller

Intelligent control system improves the operability of vacuum pump system High-performance controller realizes IoT remote control Automatically switch working modes of multiple machines Humanized human-machine interface.


  • Inlet filter

The unique pre-filter design inside the machine keeps the whole machine clean and extends the maintenance cycle. It is easy to disassemble and clean and can be reused.


  • Intelligent inverter

Adopt the top domestic frequency system, support IoT program

Reducing system cost Multi-power built-in DC reactor

Improves overall efficiency Dual-stage cascade control to ensure pressure

Transmitter signal transmission, true dual-stage operation


  • High-precision sensor

The signal processing adopts stable and efficient linear strict testing and aging to ensure the transmitter has high accuracy, good stability, strong anti-interference ability, reverse polarity protection and instantaneous overcurrent protection, and meets EMI protection requirements. Through the internal electrical appliances, the zero point and range can be accurately adjusted; all stainless steel structure, various pressure interface forms, with flush model; protection level IP65.


  • Intelligent silent exhaust system

The cooling fan adopts variable frequency control, which is more energy-saving. According to the exhaust temperature, the fan speed is controlled to suppress power waste, stabilize the system and the overall components, thereby improving the durability of the components. The variable frequency control of the fan further reduces the noise. The fan has the advantages of high efficiency, low noise, no wind blind area, and stable pressure curve.
