recommended compressor setup for 20 bar compressed air for laser cutter machine
Question
I found your website while i was trying to learn about air compressors. You have an amazing knowledge of the topic, i`m quite surprised when i saw a person had a web site about air compressors.
I`m having an issue with picking up an setup for my workshop.
I`ll use an laser cutting machine and it needs 20 bar air compression with certain ISO quality.
Compressed air quality according to ISO 8573-1:2010
- Max. solid particles Class 1
- Max. pressure dew point vapor Class 4
- Max. total amount of oil Class 1
The machine needs 20 bar but the amount of air need is pretty low. 160 l/min flow is needed.
My question is, Is it possible to get a 13 bar screw compressor with air booster to get 20 bar.
what would be the pros and cons?
If you can give your recommendations, it would be great.
Thank You.

Hi Said,
For your application, I think a piston compressor would be a better choice.
Do you intent to use the laser cutting machine all day long? Or just sometimes, or 50% of the time?
Rotary screw compressors really don't like standing still, and it sound like it will be overkill.
Check out the Atlas Copco LT compressor range:

160 l/min is about 9.2 m3/hr
LT5 would probably be a good fit for you.
Those are very reliable, industry-grade machines. They can run 24/7 if needed.
To reach your ISO class, you can install compressed air dyer (to remove moisture) and filters (to remove dust particles and oil).
For the air dryer, you could opt for a simple membrane air dryer (no maintenance): http://www.balstonfilters.com/products/membrane-ai...

Or, a very small refrigerated air dryer.
Good luck! And don't hesitate to mail me back if you have further questions!
