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.
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!
