30bar oil-free screw air compressor/40bar oil-free screw air compressor

We provide high-pressure oil-free screw air compressors, the working pressure can reach 30bar and 40bar, the double-motor  twin-screw air end are used for parallel compression. Two-stage compression means that two motors and screw heads are placed inside the chassis, and the compressed air is compressed in the first stage and then enters the second stage of pressurization, so that the working pressure is stabilized at 30-40bar.

Advantages of oil-free high-pressure air compressors

After the first air compressor is compressed, a large amount of water will be generated. Ordinary air compressors use lubricating oil to lubricate. If the water enters the air end of the second stage compression, it will quickly corrode the main engine. However, our high-pressure oil-free air compressor does not have this problem. It uses water for lubrication inside, so no matter the first-stage compression or the second-stage compression, it will not be damaged due to the production of water.

Dual inverter

Dual inverter

The inverter system has two motors that control the first-stage compressor motor and the second-stage compressor respectively, and match the speed independently, effectively saving 30% of energy.

Dual high-efficiency motors

Dual motor

Driven by dual motors, the motor is manufactured with system permanent magnet material, which is stable, reliable and energy-saving.

Twin screw host

Twin screw host

Twin screw compression system. The combined compression of oil-free screw main engine can reach the pressure of 30bar or 40bar, which is stable and reliable.

Combination sequence of compressors and introduction of post-processing equipment

Usually users who need to use oil-free screw air compressors have strict requirements on air quality. Since our air compressors are lubricated by water, there are no oil particles, and the rest are fine particles and water. The equipment for filtering water usually adopts refrigerated freeze dryer and adsorption freeze dryer, which can effectively dry the compressed air and avoid water pollution. As for the fine particles, we have three layers of filters to filter these. , you will get completely clean compressed air.

Oil-free screw air compressor technical description
Oil-free screw air compressor configuration table

Oil-free water-lubricated compressors do not mean that the exhaust gas will contain a lot of water, on the contrary, the water content of the exhaust gas is less than that of ordinary compressors. This is because the temperature of the water-lubricated screw air compressor during the compression operation is about At about 55 degrees, water molecules cannot be vaporized at this temperature, and will stay in the water-air separation barrel inside the machine, which is a great advantage compared to ordinary oil-injected screw air compressors.
