Requirements for air supply device with air as auxiliary gas for laser cutter

When using air as an auxiliary gas for Laser Cutting Machine, the air pressure needs to be 0.9MPa. Considering the pressure level of the air compressor produced by the manufacturer, a screw air compressor with a rated working pressure of 1.26MPa and a flow rate of 2.3m3/min should be selected. Special attention should also be paid to the quality of compressed air, to ensure that the dryness of the air reaches 99% and the moisture content is less than 1/100.

Therefore, the filter elements in the compressed air pipeline must use reliable brand products, and pay special attention to replacing the filter element in time; at the same time, when choosing a dryer, because there are currently two types of regenerative adsorption dryers and refrigeration dryers on the market These two types of dryers have their own characteristics, but if the requirements of long time, less maintenance and air supply stability are considered, it is recommended to choose a regenerative adsorption dryer.

When choosing the diameter of the compressed air pipeline and the pressure reducer, the flow and pressure of the output gas of the compressor must be satisfied, so as to ensure the stability of the pressure when using compressed air. In addition, permanent magnet variable frequency screw air compressors are currently available in the market. Compared with the current non-variable screw air compressors, this type of air compressor can save up to 50% of electricity, which can further reduce cutting costs.
