Aluminium Grades

[John S]

Cheers John, I did wonder about raiding a bottle and washer pump of an old car from Albert Looms! Then modding it to include a return to recirculate coolant with some filtering of course, even thought of using a cheap car oil filter for this?

for misting does it require an air feed? Or does the nozzle it self create the mist?

Michael.

Can't honestly answer the misting question as I have never done it, if the pump has enough pressure then it should mist given the right nozzle, think hosepipe but if it's low pressure then it may need a bit of a hand.
Then again a simple air spray system will mist, like a cheap spray gun.

Not sure about a car oil filter as a return system because on a car it's pumped. Someone would need to work out how long it takes to flow thru by gravity and is it backs up too much.

Sorry not been more helpful but as I say no experience.

[edit]
The professional misting systems work total loss but use very little liquid.
