Technologically Advanced And Durable Oil-Free Lubrication Permanent Magnet Variable Frequency Screw Air Compressor

Product Description:

The oil-free lubrication permanent magnet variable frequency screw air compressor is a new generation of high-efficiency, energy-saving, and environmentally friendly air compression equipment. It adopts innovative water lubrication technology and permanent magnet synchronous variable frequency drive to achieve 100% oil-free compression, perfectly meeting the strict air quality requirements of industries such as medical, food, and electronics. This product combines the advantages of high efficiency, energy saving, long service life, and intelligent control, and is an ideal alternative to traditional oil air compressors.

Why choose oil-free compressor:

Air quality plays a decisive role in many cases. If solid particles, water vapor, oil, and oil vapor appear in the compressed air system, it will lead to downtime, product damage, and even product recalls, damaging brand reputation. Worse still, it may also damage the credibility of consumers and products.

• Improve reliability
  Reliable product and system design can provide high-quality air, protect sensitive downstream gas equipment, reduce maintenance work, and extend equipment lifespan.

• Improve productivity
  The use of certified oil-free zero grade compressors ensures zero air pollution and eliminates the risk of product damage and waste.

• Improve maintainability

Our oil-free equipment is specially designed for easy maintenance and repair, providing convenient access to consumable components.

• Reduce lifecycle costs

Advantages of oil-free lubrication permanent magnet variable frequency screw air compressor:

Pure and oil-free

• Using water lubrication cooling technology, no oil coolant is used in the compression chamber to produce truly oil-free compressed air.

Safe and reliable

• A screw forms 12 compression chambers with two star wheels on the left and right, and rotates once to produce 12 air compression processes.
• The two star wheels of a single screw air compressor are symmetrically distributed on both sides of the screw, ensuring balance force. The axial and radial forces acting on the screw can cancel each other out, effectively suppressing the vibration source.
• The rotor is balanced in terms of force, with small pulses and vibrations, resulting in more reliable performance and longer lifespan.

Efficient and energy-saving

• When a single screw compressor works, each screw groove on the screw is used twice in one rotation, making full use of the screw groove space. Therefore, compared with other rotary compressors, its structural size is smaller.
• The depth of the screw groove of a single screw becomes shallower with the increase of compression chamber pressure, and the depth is zero at the end of exhaust, so theoretically there is no clearance accumulation.
• Using water as a coolant, the temperature during the compression process of the main engine is lower, the efficiency is higher, and the energy-saving effect is significant.

Silent and environmentally friendly

• The motor and screw are directly connected to drive without a gearbox, eliminating high noise components.
• The silent box type outer casing design effectively seals the noise inside the unit, keeping the overall operating noise at a low level.

Our oil-free lubrication permanent magnet variable frequency screw air compressor has the following advantages:

DH oil-free lubrication permanent magnet variable frequency screw air compressor adopts water lubrication cooling technology, and no oil coolant is used in the compression chamber, providing users with pure compressed air to meet various production needs.

Efficient host

• Directly spray pure water into the compression chamber for cooling, without using oil coolant, truly oil-free compressed air.
• The head rotor is made of stainless steel material, which will never rust.
• The bearings adopt high-end stainless steel bearings to ensure the reliability, high efficiency, and low noise of water lubrication.
• The host has no metal or metal meshing parts, the rotor is balanced in force, stable and reliable, and has a longer lifespan.

Rare earth permanent magnet variable frequency motor
The Ge Nan Deng Fu DH series water lubricated oil-free screw compressor is equipped with a rare earth permanent magnet variable frequency motor drive. Compared with AC asynchronous motors, rare earth permanent magnet motors have a simple structure, reliable operation, high power density, and wide speed range, making them an ideal power choice for high-efficiency and energy-saving air compressors.

Electric rotor
Permanent magnet rotor, with lower losses and increased efficiency by 5-10%

Small size and light weight
Compared to asynchronous motors of the same power, it is 1 to 2 machine base sizes smaller

Low noise
Reasonable slot pole coordination, magnetic field design, wider operating frequency, and lower operating noise

High starting torque
The starting torque and overload capacity of permanent magnet synchronous motors are one power level higher than asynchronous motors

Start without impact
Smooth soft start, starting current not exceeding twice the rated current

Wide speed range
The rotor does not require electrical excitation and can achieve low-speed high torque

Advantages of frequency conversion

• Ordinary air compressors usually adjust the air intake to regulate the air volume, which keeps the compressor running at rated speed. Even if the air volume decreases, the actual energy consumption will not decrease proportionally
• The displacement of the variable frequency air compressor can be perfectly combined with the user's gas consumption
• When purchasing an air compressor, the traditional cost (i.e. purchase cost and operation and maintenance cost) accounts for only 20% of the total cost, while energy consumption accounts for 80%. Compared with ordinary industrial frequency air compressors, DH series variable frequency air compressors save more than 30% energy
• Since your investment and start-up, the DH series variable frequency air compressor has been saving you costs

More efficient and energy-saving two-stage compression technology

In the two-stage compression process, the compression ratio of each stage is low, which correspondingly reduces the bearing load and extends the component life.

• By using two-stage compression, the compression ratio of each stage is reduced to minimize internal leakage
• By cooling between stages, the second stage compression is made closer to isothermal compression, achieving energy savings
