The auxiliary gases are commonly used in laser cutting are oxygen (O2), nitrogen (N2) and compressed air (Compressed Air)
Compressed air can be used in oxygen generators and nitrogen generators. Therefore, the selection of compressed air is particularly important.
So you need a Compressed Air Filter, but how to select the most situable compressed air filter for your application? Let's figure out the filter type.
Filter Type
①Particulate compressed Air Filters are used to remove dust and particles from the air.
②Coalescing filters are used mainly to capture oil and/or moisture that is suspended in the compressed air in very tiny droplets.
③Activated carbon filters remove (oil) odors and vapors.
Below tips might help you to choose the most suitable compressed air filter for your system
| ①Assess the requirements of your application. Different industry require different solution. | | ③Any specific micron of filtration performance you required? |
| ②What type of filtration is needed? Coalecent filter material removes solid and liquied contaminants from gas streams. Particulate filter media removes solid from gas streams. Absorber media removes hydrocarbon vapors from gas streams. |
| |
| ④What are the working conditions of your application? Mainly criteria of consider : Flow, working pressure, temperature,pressure loss,material of structure (stainless steel, aluminum alloy, mild steel, carbon steel) | |
| ⑤Filter flow rate from how much SCFM? Pressure drop should be less than **bar? For saving the cost and protect environment. | |
