Air Assist for 60watt laser - capacity?

[KPBadger]

Hello All

i am going to replace my noisy and over-powered ( the noise is the real problem ) air compressor with an aquarium pump such as this:-

any suggestions for what capacity i should go for ?
- similar design unit seems to be available in 45, 90, 120, 250, 45 Litres/minute.

alternatively the power rating of the motor would allow me to choose correct specification.

What do other forum members use for air assist?

(*NB i note there a few other posts on this subject but cant seem to find any numerical answer to the question )

thanks

I think minimum is 45 liters per minute. Better have some extra power, so 90 liters will be good choice.

thanks Litografa - sounds good.

i will probably put together some kind of reservoir and regulator with it, for some control of airflow.



best regards

Regulator is must! Sometimes you need high air flow, sometimes very small. With our current compressors we have not enough space for regulation
