CM45DV Low Pressure Oil-free Screw air compressor With Water Lubrication

The Advantages of Our Oil-Free Air Compressor

Our CM45DV Low Pressure Oil-Free Screw Air Compressor With Water Lubrication boasts several key advantages:

1. Truly Oil-Free

Our compressor is genuinely oil-free, with no lubrication oil in the main machine. It uses pure water to cleanse the acidic and alkaline substances from the compressed air, making it purer.

2. Lifetime Stability and Reliability

All pipes are made of high-quality 304, 316 stainless steel or corrosion-resistant materials. Our compressor utilizes direct motor-main machine equal speed connection technology, ensuring the main machine's highest speed doesn't exceed 2980rpm/min. This results in longer bearing and rotor life.

3. Energy Efficiency

Our compressor employs direct water spray cooling for the rotor and chamber, leading to higher isothermal compression efficiency. The double compression chamber technology, with one rotor and two compression chambers, surpasses two-stage compression, reducing power loss.

4. Lower Maintenance Costs

The daily maintenance for our compressor only involves changing the air and water filters, reducing the overall cost of upkeep.

The Working Principle of Our Oil-Free Screw Air Compressor

Our oil-free screw air compressor operates using a pair of main screws: the air pressure screw and the rotating screw to complete the compression process.

Compression Process

These screws are usually made of high-strength alloy steel with precise helical shapes that form a sealed working chamber between them during the intake process. As the screws rotate, the working chamber expands, drawing external air into the chamber through the intake port. Once the air enters, the rotation of the screws gradually decreases the size of the working chamber, which increases the air's compression ratio, thus raising its pressure. The compressed air is then pushed towards the machine's outlet.

Cooling and Filtration System

The compression process generates heat, which necessitates a cooling system to lower the temperature. To ensure air quality, the compressed air must also pass through a filtration system to remove potential pollutants and particles.

Applications of Our Oil-Free Screw Air Compressor

Our CM45DV Low Pressure Oil-Free Screw Air Compressor With Water Lubrication has several applications:

1. Food and Beverage Industry

Our oil-free air compressor provides an oil-free air supply, avoiding the risk of oil contamination. It is suitable for pneumatic operations, packaging, and processing in the food and beverage industry.
