compressed air

[hippee]

Hi all i have a quick question i am in the process of buying a 4kw laser Do we need compressed air to help run it and if so what sort of pressure do we need to have Thanks

Don't know if your particular machine will require compressed air, but if it does, your question might be "what volume of air will it need?" in cubic feet per minute. You're in the UK? then there might be a metric equivalent for CFM.

If you buy 4 kW laser, best way do not save on source of compressed air and ask laser supplier sell also compressor as they know better what laser need
