Compressor or Pump in UV-free booth?

Which is better in the UV-free spray booth? A compressor or a pump?

PUMP, air compressor can actually alter the molecules of the solution(highers the ph balance) and you have a better change of turning orange. That is why one of the reasons you spray your psi low when you airbrush.

the air (compressed), performs two tasks. It imparts a mechanical force to the fluid stream which is used to break the fluid up into droplets. Secondly, it provides a vehicle on which the droplets transport to the cutsomer. You only need enough pressure to perform these two tasks.

On the other hand, a pump (which an air compressor is) if used without air, must impart enough energy into the fluid to propel it through the nozzle and across the air gap, to splatter upon the customer. Certain types of nozzles do allow the fluid to break down into droplets.

In either case, a natural by product of the pump, is heat. In the case of the compressor, the heat is generated and dissipated at the compressor. In the fluid pump, the heat is generated within the fluid, in the pump. Although the moving fluid will cool the pump, heat generation within the fluid at the point of slippage can be acutely high, particularly as the fluid pressure increases. This is not good for fluid stability.

Oxidation of the fluid occurs when it is exposed to air. This happens pretty well the same for both systems and is a function of the gap between nozzles and customer. Higher pressures do tend to break the fluid into finer droplets which increase the air exposure. But the more annoying result of higher pressures are overspray and latent mist. Lower pressures reduce the overspray, largely by reducing the coverage.

'PUMP' is a general term. It alone does not describe what device is being used.

Hi,
Can anyone help me with regards to which system to use. I'm totally new to this and have no idea what to go for as far as spray tanning systems are concerned because it seems that there are so many on the market. Also what solution is best. Any advice would be greatly appreciated.
Thanks
Jackie
