Here are a couple pics of my Kremlin MX Airmix spray system.
Sorry, but it is 6 years old and doesn't look too pretty.
It does still spray as nice as it did when it was new.
There are newer models availiable that have nicer features,
but I expect they spray nearly the same.
I mounted the pump on a board and cart to make it portable.
I also mounted a small hook just below the pump to hold the
intake pipe above the can of lacquer when I wanted to drain
or change fluid. The whole system can be flushed out with
about a half of a quart of lacquer thinner.
When I want to spray, I drop the intake tube in the can of lacquer
and the pump self primes itself. The fluid it sent to the spray gun
at a 8:1 ratio , so the fluid presure at the gun is about 250-300 PSI.
The micro tip on the gun atomizes the fluid so well that it only needs
about 8-10 PSI of additional air to produce a beautiful spray pattern.
This leaves you with a minimal ammount of overspray.
The manufacturer touts about a 75% transfer efficiency.
In the cold season, I put my can of lacquer into a pail of hot water.
I might cycle fresh hot water every 10 minutes and pump the fluid
through the system a few times to get the juice at the tip up to
around 100* -110* F before I spray anything.
It makes a big difference when the temps are cold.
The piano parts, by the way, are usually kept around 60* - 65*
in my shop. I do not let parts get any colder than that.
One thing that I did not like about this gun is the hook on the top of it.
If you brushed up against the hose, the gun had a way of climbing off
the hanger and falling to the floor. I made up a 3 prong hanger, one
prong is a shaker peg, that holds the gun very effectively.
Kremlin has changed this top hook
and the newer guns do not have this problem.
This system currently runs somewhere between $2000 - $2500.
I bought my system from Industrial Finishes Ltd. in Rockville , MD.
