air compressor

[perthnovice]

Good Morning everyone,

i have a slight problem i have an s.r.t. air compressor belt drive which gives me 149 l/min but in order to run my new spray gun i need 300 l/min.

i also have another tank from an old compressor which is about 40 l/capicity

now i know that you can increase your compressors output by adding another tank but have no idea how to do this or if the extra 40l will be enough to give me the 300 l that i need so any advice much appreciated.

thank you

I think you would have to install the tank so that it is stable and cannot rupture lines through movement. I would have thought it is a process of joining the output of one to the inlet of the other. It will extend running time of your spray although I doubt it will allow for continuous spraying.

I was going through a similar dilemma recently and weighed up the pros and cons of new compressor , new tank etc etc and decided on a gun with low air requirements; see:

Asturo Low Air Spray Gun

The extra tank increase your storage capacity not your compressors out put. In order to increase your current out put you will have to run the compressor faster so it pumps more air.
Long term this may well be fatal for it, as it will be designed for a certain out put at a certain speed.

Basically you have a compressor the can move/pump/compress 'X' amount of air per minute which is 149L and you require double that [300L pm] I am afraid this really means its too small and the best thing you can do is get a bigger one ie 300L pm out put.

If you increase the size of your air receiver to meet your demands or even get one that exceeds its. The compressor will still only put out the same amount 149L pm. you will have to wait to fill the air receiver after each spray ie One minute spray might take you 2-3 minutes to recover.

If your doing intermittent spraying with long periods in between you might get away with it.
